南昌地铁车辆动力学性能研究
Research on dynamic performance of nanchang metro vehicle
摘要
Abstract
The dynamic calculation model of Nanchang metro vehicle was established and verified by using SIMPACK multi-body dynamics analysis software. The dynamic performance of the vehicle system, which includes ride comfort, curve passing and nonlinear motion stability, was analyzed in detail and the influence of the longitudinal and lateral stiffness of the primary suspension on the nonlinear critical velocity were further discussed. The results show that the ride comfort and curve passing can satisfy the dynamic requirements. The nonlinear critical speed is 153km/h, which is far greater than the design speed of the vehicle. With the increase of the longitudinal stiffness of the primary suspension, the nonlinear critical velocity increases, and after the longitudinal stiffness reaching 6 MN/m, the influence of its change on the critical velocity is small. The nonlinear critical velocity first increases then decreases with the increase of the lateral stiffness of the primary suspension, and when it reaches the maximum, the lateral stiffness is 5 MN/m.关键词
