Abstract

In this study, the slip angle which is a significant parameter in the operation of vehicle safety and control systems was investigated mathematically. With the model developed based on the Fiala tire model, the variation of the lateral force and self-aligning torque depending on the slip angle was obtained for the axle load values between 1000 N and 6000 N. By using these parameters, pneumatic trail, tyre contact area pressure distribution, tyre contact area maximum pressure value, lateral tyre deflection, and cornering stiffness were calculated. Similarly, for certain values of camber angle, camber thrust, and camber stiffness were examined. The changes of all these parameters which are of great importance for tyre mechanics depending on the axle load was investigated. A single-wheel sample with a standard 205/55R16 pneumatic tyre was investigated in terms of flexible wheel-rigid ground road interaction under dry asphalt road conditions..
