摘　　要：无公用轴独立旋转车轮转向架的车辆不仅左右车轮的旋转自由度独立,而且两轮的横移和摇头也解耦。文章通过建立无公用轴独立旋转车轮转向架车辆在直线上的横向动力学客车模型,模拟实际线路,利用新型数值快速积分法进行动态仿真,得出无公用轴独立旋转车轮转向架车辆的动态响应值,并与具有相同悬挂参数的传统客车进行比较。To railway vehicles with bogie of non-common axle,not only rotating freedom of left and right wheel are independent,but also lateral and yaw motion are uncoupling. By establishing lateral dynamics model of passenger car with non-common axle on the tangent track and simulating actual rail,the paper achieves dynamic response of vehicles with non-common axle by applying new fast explicit numerical integration,and compares main dynamic response with traditional wheels vehicle′s.
