Dynamic Response Analysis of Rigid-flex Coupling of Vehicle System Considering Flexible Wheelset
摘要
Abstract
In order to research the influence of flexible wheelset on the dynamic performance of high-speed train,the rigid-flexible coupling dynamic model of vehicle track under the condition of flexible wheelset structure was established based on CRH380 high-speed train model by using rigid-flexible coupling dynam-ic simulation method.The safety,wheel rail dynamic interaction,and trafficability indicators of vehicle models under the conditions of flexible wheelsets and fully rigid body structures were researched.The sim-ulation results show that there is a significant difference in dynamic indicators between the two models at a speed of 300 km/h,mainly manifested in the fact that the amplitude of the vertical force on the wheel rail and the amplitude of the wheel load reduction rate on the flexible wheelset vehicle model are lower than those on the fully rigid vehicle model,while the results of the vehicle vibration acceleration,derailment co-efficient,and lateral force waveform on the wheel axle have a small difference.关键词
