摘要：
Using dynamics simulation software SIMPACK to build vehicle system dynamics model of different wheel treads of high-speed vehicle and 60 kg/m rail, the effect of the change of tread conicity and suspension parameters on the dynamic performance of high-speed trains was studied and a group of new optimization parameters were obtained according to the results of the calculation. The results showed that the stability of the vehicle system was decided by the axle-box positioning stiffness and anti-yaw damper, while comfort was mainly determined by vertical damper of the second suspension, lateral damper and vertical stiffness of the vehicle system. For the wheel-rail wear, the optimized tread of the wheels of high-speed vehicle showed good wear resistance. The larger tread conicity of the optimized tread delivered better alignment performance and lower lateral vibration. On the whole, the optimized tread conicity and suspension parameters in ride quality, stability and wear were better than or close to the standard parameters vehicle, which were proved to be viable, providing theoretical basis for the unified design of vehicle structural parameters. © 2018, Department of Journal of the China Railway Society.
