Keywords:motorcycle, suspension, optimization, multibody, racing
In races, it is essential to adjust the motorcycle setup to different tracks, weather conditions and rider requirements. Vehicle adjustments are usually based on empirical know-how since decisions should be taken quickly and under pressure. Classical multibody tools cannot be adopted for this purpose because they are very complex to manage and simulations are time consuming.
This paper presents a non-conventional multibody software specifically designed for this purpose that allows to easily manage and optimize motorcycle parameters such as suspension characteristics, adjustable plates, etc. Some examples of geometry and suspension optimization are presented. A simulation of a braking manoeuvre shows also the genesis of the chatter vibration; phenomena that can compromise the motorcycle performance.
