Research on the Dynamics Performance of the Passenger Car with Controlled Radial Bogies in Negotiation of Curves

建立了可控径向转向架客车的数学模型。通过对可控径向转向架客车动态曲线通过性能的研究可知 ,可控径向转向架可以大大提高车辆的曲线通过性能 ,降低轮对冲角、轮重减载率以及脱轨系数 ,较大幅度地降低整车的磨耗功指数。

The mathematic model for the passenger car with controlled radial bogies is set up. The research on the dynamics performance of the passenger car with controlled radial bogies in negotiation of curves shows that the controlled radial bogies can greatly improve the curve negotiation performance of the cars, reduce the wheelset incident angle, the wheel unloading rate and the derailment factor, and reduce the wear work index of the whole car greatly.
