可倾车体式客车方案初探及动力学性能分析

要探讨发展可倾车辆对缓解我国铁路客运紧张局面的可行性,针对我国铁路实际提出了研制可倾车体式客车的一种具体方案。对带主动控制的可倾车体式车辆建立了21个自由度的数学模型,通过动态曲线通过的动力学仿真计算,得出了可倾车辆在保证必要的旅客舒适度及行车安全的前提下,可提高30%～50%的车辆曲线限速的结论。

In this paper,the feasibility of developing tiltable cars to ease the crowded railway passenger traffic in our country is inquired into,a concrete scheme to develop tiltable-carbodyed passenger ears incorporating railway practices in our country is put forward.For cars with actively controlled tiltable carbodies,a mathe- matic model with 21 degrees of freedom is eastablished.Via dynamic simulation computation of dynamic curve negotiation,it is obtained that on condition to ensure necessary passenger comfort and running safety,the tiltable cars can raise the limit- ing speed on curve by 30%～50%.
