城市轨道车辆车体横向振动的仿真
Simulation of Lateral Vibration of Urban Rail Vehicle Body
摘要
Abstract
The influence of track irregularity on vehicle body' s lateral vibration is studied, and the performance of vehicle body' s vibration is evaluated. At first, a simplified urban vehicle's model is established. Then the track irregularity is described and the track power spectrum in space domain is transferred into the spectrum in time-frequency domain. The 3D model of the vehicle's body is established with PROE software, and then the wheel-rail model and the train's simulation model are established with the use of the dynamic simulation software SIMPACK. Finally, with the height irregularity as excitation function, the lateral vibration response of the vehicle's body is computed. Referring to the domestic standard of lateral stability, the lateral performance of vehicle's body is evaluated.关键词
