摘要

根据中国标准地铁列车时速80 km B型车的设计要求和相关标准建立车辆动力学模型，基于车辆系统模态特性与运行速度、悬挂参数的相关性，利用傅里叶幅值扩展法对不同变量因子的灵敏度进行分析。依据动力学指标建立优化设计模型，对一系悬挂参数和二系悬挂参数进行优化组合，利用优化后的悬挂参数对车辆在不同工况下的动力学性能进行评估，并结合“车辆-轨道”耦合动力学模型，简要分析了车体和转向架模态对车辆平稳性和振动的影响。计算结果表明，基于优化后的悬挂参数，中国标准地铁列车时速80 km B型车的各项动力学性能满足标准和设计要求，车体和转向架的耦合性较弱，车辆系统有一定的安全裕量。

Abstract

According to the design requirements and related standards of standard metro train 80B

a vehicle dynamics model was established. Based on the correlation of vehicle system modal characteristics with running speed and suspension parameters

the sensitivity of different variable factors was analyzed by Fourier amplitude expansion method. The optimal design model was established according to the dynamic index

and the suspension parameters of the primary and secondary series were optimally combined. The optimized suspension parameters were used to evaluate the dynamic performance of the vehicle under different working conditions

and combined with the vehicle track coupling dynamic model

the influence of the vehicle body and bogie modes on vehicle stability and vibration was briefly analyzed. The calculation results show that

based on the optimized suspension parameters

the dynamic performance of the standard metro train 80B meets the standards and design requirements

the coupling between the car body and the bogie is weak

and the vehicle system has a certain safety margin.
