摘　　要：利用模态参数柔性轮胎模型模拟车辆在起步过程中的动态响应特性,并以相应轴头加速度响应特性的试验结果间接给予了验证。从而解释了车辆在起步时需要较大驱动力矩的原因。其结果亦解释了文献中所描述的起步过程现象。Using modal parameter model for flexible tire, a simulation on dynamic load response characteristics of both driving and driven wheels in starting process is conducted, which is indirectly verified by the test resuits of acceleration response characteristics of wheel axles. This gives explanation on some phenomena in vehicle starting process both found in real world and described in literature.
