Assessing Tire Performance from Vehicle Dynamic Transfer Functions
The aim of this study is to develop techniques which can be used to assess tire performance for a motorcycle. This approach focusses on using vehicle level performance parameters and transfer functions to assess tire performance. Several vehicle level dynamic parameters and transfer functions like cornering speeds, lateral acceleration, roll angles and roll rates, roll transfer function, lateral acceleration factor respectively are used to understand the effect of tires on motorcycle dynamic behavior. Tire behavior is then studied by assessing maneuverability of the motorcycle in maneuvers like slalom and lane change. A subjective assessment is then performed to understand rider’s feedback and relate the same with objective findings. Interesting results on the relationship between subjective perception of the riders, tire force characteristics and objective measurements are presented.
