基于车-椅耦合的转向架垂向悬挂系统阻尼比协同优化
Collaborative optimization of bogie vertical suspension damping ratio based on body-seat coupling
摘要
Abstract
For the problem of the optimal damping matching of high-speed train bogie vertical sus-pension system,according to the 1/4 body-seat vertical vibration model of high-speed train,using Matlab/Simulink,a collaborative optimal design simulation model for damping ratio of bogie ver-tical suspension is established.Taking optimal ride comfort as target,a collaborative optimal de-sign mathematical model for damping ratio of bogie vertical suspension is built.The track vertical irregularity as input,the primary and secondary suspension vertical stroke and the ratio of dy-namic and static force for primary suspension as constraint conditions,a collaborative optimiza-tion design method for damping ratio of bogie vertical suspension damping ratio based on bogie-body-seat coupling is presented.With a practical example of high-speed train,the damping ratio is designed and validated by simulation.The results show that the ride comfort of high-speed train has been significantly improved under the damping ratio optimized and the seat vertical fre-quency-weighed RMS (Root Mean Square)acceleration value is reduced by 21.7%.Thus,the collaborative optimization method is correct.关键词
