Solidworks 2007 Full Suspension

H4 Bicycle - I designed and built this 4 wheel bicycle with Solidworks 2007, and rendered it using 3D Studio Max Vray.

Yeah, I mostly did my modeling as an academic exercise (lacing wheels is interesting): I'll tell you, I think it's overkill for sure and BikeCAD has it's place and merits. That should be looked at for sure. Go back and do a search for any threads with 'WWTP' in them and you'll see my process from start to where I am now.

I still believe that I learned a lot about frame design by building a model though. It forces you into geometry hell in a very intimate fashion. Trail, Offset, Axle-to-Crown, head tube angle, seat tube angle, effective top tube, all become interesting things to look at and understand. For instance, take ETT. It's a BS number as it turns out.

ETT is a function of heat tube angle, top tube angle, head tube length and then the rider fit numbers. Once modeled, it was easy to play with and see that by just changing the head tube length, the ETT may change by 5-10mm and that's the difference between a bike fitting and not fitting. Anyway, I digress. It's worth doing just for the academic experience I'd say. It isn't going to make you a better print than say a 2D system like AutoCAD, BikeCAD, or even a drafting board/pencil/ANSI E sheet of paper. What it will do is keep you very intimately involved with the bike as it evolves.

For instance, in one of my updates, I show the BB shell and the dropouts in a jig for mitering my chainstays. That jig came straight out of my model. It took me an hour or so to make the jig, create PDFs to send to the garage computer, and then another hour to make the thing right off the PDFs in the garage and it was dead on without anything else. Those are the benefits of having a solid model in this case. Secondly, now that I have it, it's fairly easy to tweak and change the geometry and create different bikes. So that's cool.

Lots of work on the front end, very little to create something different and full sized prints are instant. All that said, you need to learn SolidWorks first. Create lots of stuff. Learning about datum is going to be the biggest thing to help you succeed in frame modeling. I've got years and years of modeling experience and will say that a frame is anything but a trivial problem if done in round tubes. One thing that I could suggest is doing it as a '2d' model.

In other words, make your tubes out of rectangles so that they are extruded rectangles and stitch the front triangle together that way. To clarify, from the side view, rectangles look like tubes and are much easier to manipulate in SolidWorks than round tubes. The front triangle is the 'interesting' part of a frame anyway. I still assert that the rear is boring. The only real dimension there is the chainstay length. Granted, getting the tire, chainrings, etc. Fit in there is an interesting problem, but it's not interesting from a frame size/geometry perspective at all.

When you've built a frame or two, then modeling that stuff would be interesting as you can start to do very custom things like PVD's just done on the Dopplebarney. That's very slick stuff. Yea so what i would like to do is design and build a full suspension frame in solid works after doing some FEA on the frame. The trouble that i am running into is that i do not know how to assemble tubing at different angles.Have you taken any SolidWorks classes? Because I can tell you how to do it but if you don't understand the terms or how to then it's pointless and a waste of my time. Their are plenty of SolidWorks resources on the net.a good one is EngTips. Are you familiar with Top Down and Bottom Up approaches to modeling?

What version of SolidWorks do you have? I am using 2009.

I have a file that I might be willing to share with you that can get you started. I've been using SolidWorks since its beginning and also have thousands of hours on Pro/E.so I would be willing to coach you but not in this thread. Send me a PM if you want any frame files from solidworks.

I design quite alot in SW, and bikes are just one of the things. I have a very detailed fully I designed for a class in school, almost drew every component to accurate dimensions, so I have quite a few blocks if anyone needs them. Other than that - I've always heard it said, and I'll back it up myself - Take a class at a local community college. You will learn the program much better! Then watch the youtube tutorials lol. Just learning from youtube is hard if you don't have a good foundation in the program. Send me a PM if you want any frame files from solidworks.

I have just started playing with solidworks trying to design. Do you have any files I could mess around with. Good call on using Solidworks! I use it all the time at work, and I have it at home for bike designing. I know of few people on here that would admit it, but if they had access to that software and its mountain of theoretical testing tools, they'd be all over it in a second and not calling it overkill. It is extremely expensive I know, but being able to see my dh bike's weight, stress distribution, and if the rear linkage will have the proper leverage ratios before I start welding is worth its weight in gold to me.

BikeCAD really is great, but why not have limitless features and toys, just in case? Better to come to the water fight with a fire hose than a squirt gun, I say. Anyway, you ought to look at the Solidworks tutorials that deal with sweeps and lofts.

Those tools will be invaluable if you're designing something with butted tubing. There are many ways to design a frame, and you can decide which is best for your purposes. Here is a very broad overview of what I do: 1) sketch some construction lines on the right plane that goes through the origin. Draw up the basic angles and distances your frame will need. This will serve as a guide, as well as possible sweep guide curves for your tubes. 2) Sketch and mid-plane extrude your bottom bracket shell tube. Be sure it's a mid-plane extrude, not Blind or anything else, or it'll be a pain if you need to mirror any features from the left or right side of the bike to the other 3) Create a plane off of the center axis of your bottom bracket shell that is perpendicular to the down tube's direction. Decorative Arabic Fonts Style.

On that plane, draw your downtube cross section. Now extrude-boss, loft, or sweep along a path to the area of the head tube. 4) Do the other tubes and features that come off of the bottom bracket (seat tube, stays, etc) on their own planes 5) Continue this process of Create plane >draw profile(s) >extrude/loft/sweep until everything is how you want it. Hope that made sense, and please feel free to ask if you need specific help. Hi all, I am a newbie in SW, but im determined to make my own titanium FS frame. I am looking for as much as i can find materials for building a FS frame.

I can see that you have done a awsome work and I hope to be as good as you. I have no intention to sell frames, just for my own satisfaction to DIY.

I have been looking for some tutorials, but it takes me for some time. If you have some materials which can help me, I would much appreciate and would be thankfull. My mail is Well, you're not going to learn SolidWorks here since this is a mtn bike forum.best for you to log onto then join the SWx forum. Then get some training via your reseller or a local community college. Another good resource is the SolidWorks Bible. My six year old son has been using Solid Works for the last year at my supervision. [QUOTE=Mark Landsaat;7498505]Hi Ryan, I have been using SolidWorks in the bicycle industry for almost a decade and have put together a few videos that I posted on youtube.

They explain some of the basic setup techniques I use for building a suspension frame using SolidWorks. Check them out, I think they will be helpful with your project. Also, if you have any questions on setting up your model, let me know and I will be happy to give you some guidelines to get you started. Hi, I recently aquired the 2009 version of solid works to design some bike frames and i have been watching your videos on youtube to try and get started but i'm still a bit stuck. I was wondering if you could put a video up showing the step by step process of how to draw a basic frame or if you could send me some instructions. My main problem is creating a geometry feature and putting the tubes on it. I can draw simple objects such as bolts but can,t figure out frames.

Any help or advice would be greatly appreciated. Sorry I cant send you my email address because i haven't had 10 post's yet but if you are willing to help then i'll just put 10 random posts so i can give my email to you.

You see that hot looking Camaro up above? That’s a thousand features of SolidWorks surfacing coolness you’re about to create. There’s an even cooler aspect to this as well. Matthew Perez, a Certified SolidWorks Expert (CSWE) and designer of injection molded parts, created this tutorial for you to learn all he has learned about modeling a car with SolidWorks. Oh, and he’s providing it to you absolutely free. Here’s the story and the download.

Get your surface slappers ready. Modeling a Car in SolidWorks Matthew first brought up his on the SolidWorks Forums. It’s a great read with a lot of interaction with people on various aspects of the model. I followed up with Matthew to find out more about his background, why he chose to model the Camaro and make it free to everyone. I am/was an engineering student but haven’t finished school yet for various reasons.

For the past 10 years (during school and the past 5 years full time) I’ve worked as a designer/fabricator for Virginia tech transportation institute. I really enjoy the design side of things over the engineering side so ive really pushed myself in that direction. I’ve been using SolidWorks for about 2 years or so now.

Before that (and still), I used UGS and Inventor, as well as a few other programs. I was introduced to parametric modeling software when we received Inventor in 2007.

Before that I had played with Autocad off and on for school but really never did much with it. SolidWorks is great and it really gave me the platform to pursue surface modeling. Shortly after using SolidWorks I began preparing for the certifications. I’m completely self taught and do not have any formal CAD training. I received my Certified SolidWorks Professional (CSWP) certification for Surfacing, Mold tools and Sheet Metal, then went on to get the Certified SolidWorks Expert (CSWE) certification shortly after. Modeling a car had always been something I wanted to do but didn’t know where to start (as I’m sure most users). I tried a few cars before I gave the Camaro a shot.

The choice for the car really came about because someone posted their attempt on another forum with a few questions. I really just wanted to give it a try and went from there. Since there were really no free tutorials out there for cars in SolidWorks I wanted to document my attempt at the car which is what I’ve provided. It’s less of a “do this, do that” document and more about explaining my thought process through the model.

It’s also unedited, rough and written during my first attempt at the car. I really enjoy CAD work and helping others learn.

I feel this transfer of knowledge should be free to those who want to learn so as of now everything I do is available to anyone who wants it (not the files, but the knowledge;-). Here are some renderings of the model Matthew worked up real quick in PhotoView 360. Just imagine it, you could do the same. The SolidWorks Camaro Tutorial The step-by-step.pdf is a whopping 296 pages of Matthew’s insight about modeling a Camaro in SolidWorks.

Don’t worry, there are a lot of images which show you what he does. The only thing you’ll start with, besides the step-by-step, are the blueprints (via ) which help you layout the profiles and guides for the surfaces. This car wasn’t the easiest to model because of some of the lines, but I had fun doing it and wanted to pass it along to maybe show others how I approached it. – Matthew Perez Taking on the challenge? Tell us your thoughts, ask questions, throw out some tips and by all means, let Matthew know how much you appreciate the work he’s put into this.

A big thanks to for tipping us off about this! Filed: Tagged: About Josh Mings. I love this tutorial and the whole concept, let me start by saying Thank You So Much Matthew! Sם I’ve started self-learning SolidWorks around 18 months ago and just recently became a CSWP. I’ve bought Solid Professor’s Premium package and I even bought (waiting for arrival) for the latest Gallardo tutorial. I really appreciate you “giving away” this tutorial for ABSOLUTELY FREE and I’d like to help in any way I can, I’ve promoted your tutorial on Facebook and among my SW community and I think it’s a very good practice towards the CSWP-Surfacing exam I want to tackle next month.

Once again thank you so much for this tutorial. Will also take the next Complex Speakers tutorial afterwards, thanks for that too. Just a little request for the future, I’d love to try to build an internal combustion engine assembly, wouldn’t mind even paying for a decent tutorial for that. In case I can help in anyway just hit me on Facebook – Shai Phyzix.

Pvc bushings will work. I've run the PVC without grease fittings(greased every few times a year), if you buy a bolt thats long enough to not have threads on the pvc(chop the ends for apearance if you choose) it should last 2-3 years, mine did on another project. If the pvc sits on the pivot bolt threads, a season of riding perhaps, but it might be sooner depending on how much you ride. When the PVC wears out, it will get sloppy quick and if left unfixed will damage the metal parts. This is the reason most people have bad experiences with them, IMO You can get urethane bushings online from advance auto parts that will fit into pipe/tubing (using the black water pipe I had to sand the lip on the bushing a little). Do a search for universal bushing on their website I'd go to and choose which one you like (go with the 9.8113 style, they are halves, MUCH EASIER for you looking at your setup) goto advance (partsamerica link) and order them, around $6 a 'pair' (2 full bushings, or 4 halves) you might be able to get them ordered at a local store as well you could also get 9.8107 and cut them in half, that would be less diameter if you need it.

But some material mates up really nicely, and you wouldn't need a bushing.This is what I'm hoping for, although, finding 13 long bolts might be hard. I don't know what to do with the short bushings ryf suggested.

Since the whole thing is 12' long, AFAIK I'd need 12' long bushings How did you solve the rear end drivetrain issue, again? The only problem I'm having is not knowing what to use for a rear hub. I was thinking of a.25' steel plate with a bearings in the middle for the axle shaft. You could buy any of the ones with a flanged outside edge and cut them in half, then turn down the inside to get the desired diameter (slightly larger than your tube/pipe.

The lips on the outside edge will keep them in place. I used 9.8112 and if you leave the lip as is, it will not fit inside 1' black pipe, cutting it as stated, and turning down the middle section into a slight wedge shape will allow it to be hammered or tap into place (leave a flat spot for binding and to make sure it goes straight. Tap them witha hammer and a buffer board. Or you could use the two I mentioned that are already large wedges and it will self align (put them on the end of the pipe) I turned them using a bench grinder and a bolt, wear gloves and let it spin against the wheel, it will go quick so watch and check often.

Yeah, I'm uploading them to photobucket and them linking them. I'm gonna have a cv axle or something similar going to the wheels, and the sprocket and caliper are going to be in the middle of the black box. Something like this Now only to know where to get those bearings http://www.gokartforums.com/images/my_gokart/gokart94.jpg. That might be a 3 horse because of that recoil set up. At least all the briggs 5 horses i own have the recoil mech in the housing you took off. I used a screw driver and put it on those nubs and used a hammer to get it off. The to take flywheel off you take off all seperate items then i use heavy duty screwdriver and pry the flywheel off against the block be sure not to pry agaisnt anything that would be ruined, then i lightly tap the shaft with a hammer (if it were a 5 horse with a nut i could make nut flush with whe shft to be sure and not wreck the threads).

Usually it will pop right off after a few hits.
