I highly doubt a team will simply hand you over their entire design. Do you not have this information from one of your previous vehicles?

Thanks for your reply.
No I don t have any required vehicle information with me. After understanding the importance of virtual testing in vehicle development,I decided to spend more time on analysis but not on data acquisition.So I am making a request here.If the teams dont like to share the current vehicle information,they can (if they are interested) share the information of any of their previous vehicles. The only intention of the current work is to establish a virtual testing methodology. .........................................................................................................................................................

I understand you're doing the good thing.
And it's not a question of not wanting to give It's about the collection of the entire data and give JLT. You should instead go to a specific city team and see their vehicle.

As an engineer, you have to make some assumptions. This would be one of those times. If you're a post graduate, I would expect you've heard that a few times by now. I understand what you're trying to do, but asking other teams for sensitive data probably is not the best way to go.
As far as the 3D CAD model - you are NEVER going to get that from any team. End of story. Your team should be producing its own 3D model prior to building. The things you're asking for can and will vary from team to team, year to year. That sort of information is generally kept VERY close to the chest as it gives away a ton of information about the design that went into the systems(mass, COG, parts, etc). If you can't figure it out from video or pictures of another team's car, you definitely will not be getting such specific information from the team. Even previous vehicles are generally kept locked up. Again, make some assumptions, that will get you farther than asking other teams for sensitive data.

I agree. If it is just an academic exercise to get this system up and running than the number almost do not matter. I will give you a head start.
wheelbase: 60-62 inch tracks: 52-56 inch RCs: 0-15 inch off ground castor: 5-15 degrees steering angle: up to 40 deg % ackerman: 10-50% ground clearance 8-12 inches travel: 8-12 inches weight: 375-425 lbs % F/R anywhere from 30/70 to 50/50 % antidive: who cares I think I just described the characteristics of a typical car to finish in the top half at competition. Pick what is reasonable and just go with it. The results you get won't be any worse than if I were to scrounge up some broke-a$$ CAD model from 4 years ago for a car that nobody remembers and didn't win (which I won't). If you have specific questions about selecting a parameter or 2, I am sure lots of people will chime in (with often conflicting answers) |
