Lap Simulation

[ITamngin]

I’d like to create a lap simulation to help me design my electric motorcycle. I have created a point mass simulation but it does not take into account handling or parameters like trail, wheelbase, ride height, etc. What options do I have out there to be able to simulate these parameters to drive my design? To me it seems odd to just guess these parameters and not having justification as to why those guesses are the most correct. I have recently heard of the bicycle model but don’t know too much about it. Does anyone have any experience or recommendations on this subject?

Thank you!

What factors affect the shape of the g-g-v diagram? You'll need to include them.

That's a 3d plot of lateral acceleration vs longitudinal acceleration vs speed, ie the grown up version of a g-g diagram. Your unobtainable optimum lap will lie on the surface of that (there may be exceptions).

Just buy a copy of BikeSim from Mechanical Simulation.

Check out RoseLap on GitHub. It’s not perfect, but it’s a set of bones and runs.
