5'0 in cm. Hello, We only have experience with Autocad 2D design (work) and a bit Fluent and Gambit (college classes). The software learning curve does not worry us too much (we don't have a deadline or other commitments) but we would like to choose a package and stick with it.

We want to take an engineering approach to this. Our main worry is making something that will brake/crack under braking load or something that will flex so bad it will cause a crash.

After we make it safe, we will try to make it fast.:) We plan on using a 600cc engine that will make about 120 hp. So I would say that simulation is more important to us than making the 3D model. RE: Motorcycle design software (Mechanical) 18 Feb 11 12:07. 100K may sound a lot but you could burn through a bunch of that buying software and getting some basic training etc. You may be better with a mid range product like Solid Edge or Works, they have add ons for FEA & CFD that may be more or less integrated.

However, I don't know for sure how good the analysis packs are. Also, with FEA & CFD while I believe they've got a bit better you really need to know what you're doing to use them or you can get a lot of 'GIGO'. This has often been lamented on this site, people running FEA without really understanding what it's doing or validating their models.

I believe I've seen motorbikes, or maybe was it a scooter, done in Solid Edge so it's probably possible. We discussed this and even though this is a labor of love we kind of hope that it will turn into something else.

We are not too keen on buying some mid range software, spend time learning it and then finding out that we need something better and do it all over again. Not to mention that switching from one platform to another would be very difficult in terms of saved files.

Also, we are not looking to reinvent the wheel of motorcycle design and development. We know from the college classes that knowing what you're doing is a key element in CFD. I'm sure FEA is the same. So far from what I've read the most appropriate packages for us would revolve around Catia and NX. Catia has Abaqus. Don't know how it rates against Ansys. Fluent might be a little overkill for the aerodynamics since a motorcycle's aerodynamics are not that important but we have worked with it a bit and we liked it.

Also, I think it will be very good for the air intake and exhaust design. RE: Motorcycle design software (Civil/Environmental). One of the advantages of using NX is that while you can interface to most all of the industry standard 3rd party analysis tools, you can also perform most all of those tasks INSIDE of NX using the integrated suite of CAE tools based on some of the most powerful and well implemented applications available today in any form, integrated or otherwise. For a review of the breadth & depth of what NX and Siemens has to offer in this area, go to: John R. Product 'Evangelist' Product Design Solutions Siemens PLM Software Inc.

Or calculix for the FEA. OpenFoam is a fully functional professional CFD that went open source a few years back. It is used by at least one automotive OEM. Real automotive engineers tend not to use the bundled analysis packages, they export the solid models and mesh them up in other packages. I wouldn't get too hung up on the FEA, the reality is that you don't know what the loads really are. Cheers Greg Locock New here?

Welcome to 'Build your Bike' web-site! You can have fun draggin bike parts around the stage, changing the parts you want. You have a bunch of parts and more will be ready in the future. We addedd the background options to give your bike a cool stage, too.

Dont forget to send us, by your usual client, an email with attached a caption image of your browser with your unique bikes: we will show them in our upcoming 'Users Gallery' Best Practices: Even if you can endless change parts position, don't forget to start from part you want to leave behind the others like the frame and the whells. To be continued.
