摘要

研究车间阻尼器及其参数对高速列车动力学特性的影响,对于列车车间悬架设计和优化具有重要意义。本文首先对具有车际减振器的高速高铁列车进行了多体系统动力学建模,提出并验证了用于描述减振器阻尼特性的简化参数化模型。基于MBS模型的仿真结果表明,在不增加轮对侧移力和脱轨系数的情况下,高速列车车厢间阻尼器能明显减小相邻车厢连接通道处的横向振动,从而提高高铁列车的整体乘坐舒适性。此外,车际减振器可以抵抗剧烈的横向冲击,保证两列高速列车相互碰撞时的安全。所建立的高铁动车组MBS模型是一个准确、实用的平台,研究结果对高铁动车组后续振动分析和车际悬架优化具有一定的参考价值。

Effect of an inter-vehicle damper on the dynamics of a high-speed train
It is meaningful to understand the effect of inter-vehicle damper and its parameters on high-speed train dynamics in the context of train inter-vehicle suspension design or optimization. In this study, Multi-body System (MBS) dynamics modelling of a high-speed CRH train with inter-vehicle damper is firstly carried out, in which a simplified-parametric model was proposed and validated to depict damping characteristics of the damper. Simulation results using the MBS model show that inter-vehicle damper devised in high-speed train can obviously reduce lateral vibrations at the connecting passage of adjacent compartments without increasing the wheelset lateral shift force and derailment coefficient, thus it can improve overal ride comfort of the CRH train. In addition, inter-vehicle damper can resist severe lateral shocks and guarantee safety when two high-speed trains pass each other. The developed MBS model of the CRH train is an accurate and useful platform, the obtained results in this study are also valuable in following vibration analysis and inter-vehicle suspension optimization of the CRH train.
