    During testing, our chain fell off of the sprocket and we believe it to have been from the mounts deforming and allowing it to skip off. Make em hefty!

    Pretty much all we change year-to-year is the balance of stiffness/weight.

    If you want a new way, maybe try magnets?

    Not even search, just a quick scroll would have done enough.

    But seriously VIPIN, we are not going to design your car for you. How could we possibly tell you forces in your mounts without knowing...

    OT, enjoy:

    Yaw inertia doesn't matter when you don't need to rotate! Perfect! http://fsae.com/groupee_common/emoticons/icon_wink.gif

    Yeah I see what you're saying. But it's better stated that having independant wheel control can increase the yaw moment acting on the car, while added mass at the wheels will generally increase yaw...

    I would still say it matters. Even if they managed a super amazing control system so that the perfect amount of power was always applied to all the correct wheels, the car still needs to rotate and...

    I notice that you said you are/were "improvising" to make your car better in the aspects you have stated. Instead of improvising, shouldn't you be planning and engineering a solution to your problems...

    In the past, our team has used two spring pins at each connection. You can size them based on bearing/shear stresses given whatever torque you are designing to. There has never been a lot of play in...

    It's also worth noting that doing as you suggest, increasing unsprung mass by moving items (motors) to the wheel assembly will increase yaw inertia. Not so good for cornering.

    Abhilash,

    As Pat said, pictures would help us better understand your question. Although in general, having the "damper axis" change direction is not a problem. Need pictures to help out more...

    You, sir, should also read the rules and/or stop giving blatantly wrong advice. It is necessary to have a suspension. See T6.1.1

    Choosing appropriate ackermann is about getting the most lateral G out of your tires in a turn. Become familiar with your tire data and the solution will present itself.

    As I don't have much expericnce with the FEA, can't help you much there, sorry pal.

    As for the spring coefficient of the tire, as acedeuce said you can get it from tire data, or testing, but tire...
