摘要：近些年来我国高速列车的不断发展，列车的速度不断提高，特别是高速动车组的运营标志着列车的速度上了一个新的台阶。但是随着列车速度的不断提高，列车自身的振动幅度也在不断的增加，成为危害列车安全运营的主要问题之一。因此，研究这个课题并且找到列车振动的主要原因与解决方法是十分关键的。要了解并逐步解决这个问题，需要对列车进行动力学仿真，本论文根据国内高速动车组利用SIMPACK建立了列车的仿真模型，模拟并研究了列车在同一速度的情况下不同部位的振动幅度、列车在不同速度情况下同一部位的振动幅度与列车在同一速度的情况下车体不同部位的不同的振动幅度，通过从这三个不同的层次与情况来剖析国内高速动车组的振动特性，并且得出高速动车组振动特性一般性结论。58298

Research on Train Vibration Characteristics

Abstract：In recent years, the continuous development of China's high-speed trains, the speed of the train is constantly improving, especially high-speed EMU Operation marks a new step on the speed of the train. However, with the continuous improvement of the train speed, the amplitude of the train itself is constantly increasing, and become one of the main problems that endanger the safety operation of the train. Therefore, it is very important to study the problem and find out the main cause and solution of train vibration. To understand and gradually solve the problem, the need to train on the dynamic simulation, this paper according to the high speed EMU using SIMPACK simulation model was established based on the train. Simulation and Study on the train at the same speed in different parts of the vibration amplitude and train in the same speed in the same site vibration amplitude and train at the same speed in different parts of the body different vibration amplitude by from the three different levels and to analyze the vibration characteristics of the high speed EMU, The general conclusion of vibration characteristic of high speed train is obtained.
