Abstract:

Tyre is the only connecting part between the vehicle and the road, which provides all the vehicle driving, steering, and braking force. Accuracy tyre dynamics models are increasingly needed. Because of the structure nonlinear and complexity of contact state, how to establish effective tyre model is always the difficulty of vehicle dynamics modeling. Based on the idea of modal parameters modeling, establish the quantitative static tyre model in the vertical direction and research the effects of modal root and tread model on this method. With the tyre vertical load on the road, research the pressure and deformation features in the tyre contact patch and the interrelation between the horizontal load distribution, contact length, and sinking amount. Use the iterative method to establish tyres static vertical model on the horizontal road. The theoretical calculation and experiment results indicate the relation curves of vertical force distribution and sinking amount, vertical load, and length of contact patch and show good agreement on the qualitative and quantitative aspects.
