Analysis on Motorcycle Turning with Multibody Dynamic Simulations

Multibody dynamic simulations have become a powerful tool to analyze motorcycles. One of the purposes of motorcycle simulations is to complement experimental data and obtain immeasurable physical values. The other purpose is for parameter studies. With computer simulations, one can easily change motorcycle parameters without changing other parameters. In this paper, turning simulations at the circuit corner are conducted to demonstrate the effectiveness of simulations for these two purposes. By estimating the tire forces at the turning, the remaining friction margin is revealed. The parameter study shows the effects of influential parameters on maneuverability and stability.
