摘要
通过建立17个自由度的车辆横向振动动力学模型,研究了二系横向阻尼系数对车辆横向振动的影响。结果表明,二系横向减振器失效或其阻尼系数过大都会造成车辆横向运行平稳性变差。计算结果对高速列车的日常检修、维护保养具有一定意义。
By setting up the dynamics model with 17degrees of freedom for the lateral vibration of vehicles,the effect of the secondary lateral damping coefficient on the lateral vibration of vehicles is researched.The result shows that failure of the secondary lateral damper or the damping coefficient being too big can cause the lateral running stability of vehicles to become worse.The calculation result has certain significance to the routine inspection,repair and maintenance of high speed trains.
