以配装30 t轴重转向架的货车为分析对象,利用动力学分析软件NUCARS对该货车进行蛇行运动稳定性分析,得出原型方案空、重车的临界速度和一系橡胶垫纵、横向定位刚度、转向架回转阻力矩、转向架抗菱形变形刚度、抗剪切变形刚度和踏面等效斜度对车辆临界速度的影响规律。
Taking the truck equipped with 30 t axle truck as the analysis object, the dynamic analysis software NUCARS was used to analyze the stability of the wagon hunting. The critical speed of prototype scheme and heavy truck and the longitudinal and transverse The stiffness of the bogie, the moment of bogie turning resistance, the deformation resistance of the bogie, the stiffness of the bogie and the equivalent slope of the bogie on the critical speed of the vehicle.
