摘　　要：充分考虑车辆在转弯制动工况下,因纵向、侧向加速度的存在而引起的轮胎所受垂直载荷的转移,建立了汽车弯道行驶的八自由度整车动力学仿真模型。对转弯制动工况下车速、轮速,滑移率以及车轮垂直载荷转移进行了仿真计算,仿真结果表明该模型可以全面预测车辆在弯道制动时的受力和运动情况,对于快速开发ABS系统有很好的参考意义。Considering the influence of wheel vertical load, the paper establishes a dynamic model of 8 degrees freedom for an entire vehicle when driving in the crooked roads. Based on this model, the changes of vehicle speed, wheel speed, slip ratio and wheel load were simulated. The simulation result shows that the model can predict the forces and movements of vehicle under braking in turn condition. The model can be used in further improvement and research on ABS.
