Abstract

The new theoretical tire model for force and moment has been developed by considering a two-dimensional contact patch of a tire with rib pattern. The force and moment are compared with the calculation by finite element method (FEM). The side force predicted by the theoretical tire model is somewhat undervalued as compared with the FEM calculation, while the self-aligning torque predicted by the theoretical tire model agrees well with the FEM calculation. The shear force distribution in a two-dimensional contact patch under slip angle predicted by the proposed model qualitatively agrees with the FEM calculation. Furthermore, the distribution of the adhesion region and sliding region in a two-dimensional contact patch predicted by the theoretical tire model qualitatively agrees with the FEM calculation.

考虑力和力矩二维接触片的轮胎理论模型

通过考虑具有肋条花纹的轮胎的二维接触片，建立了新的轮胎力和力矩理论模型。并与有限元法计算结果进行了比较。与FEM计算相比，由理论轮胎模型预测的侧向力在一定程度上被低估，而由理论轮胎模式预测的自对准扭矩与FEM的计算非常一致。该模型预测的二维接触片在滑移角作用下的剪切力分布与有限元计算结果基本一致。此外，由理论轮胎模型预测的二维接触片中粘附区和滑动区的分布与有限元计算定性一致。
