列车制动系统缓解性能的动态模拟

用气体动力学原理建立模型，预测了列车不同编组长度，不同减压量后的缓解性能。预测结果表明：列车的缓解性能与列车的编组长度及坟量有关，列车越长缓解波速越慢；减压量越大缓解波速越快；缓解波按非等速由前向后传播。

The Simulation of Reiease Performances of the Train

The train's release performance has been predicted by the present mathematical model of train's air brake system,which has been estalished basing on gas dynamics .The prediction shows that the release performance is related to the train's length and brake reduction as follows:Themore the brake reduction is,the faster the release wave propagates;the longer the train is,the slower the wave propagates; and the release wave propagates to the end of the train with varying speed.
