Transfer Path Contribution to Floor Vibration of Metro Vehicles Based on Operational Transfer Path Analysis Method
文献摘要：
Operational transfer path analysis(OTPA)is an advanced vibration and noise transfer path identification and contribu-tion evaluation method.However,the application of OTPA to rail transit vehicles considers only the excitation ampli-tude and ignores the influence of the excitation phase.This study considers the influence of the excitation amplitude and phase,and analyzes the contribution of the secondary suspension path to the floor vibration when the metro vehicle runs at 60 km/h,using an analysis based on the OTPA method.The results show that the vertical direction of the anti-rolling torsion bar area provides the maximum contribution to the floor vibration,with a contribution of 22.1％,followed by the longitudinal vibration of the air spring area,with a contribution of 17.1％.Based on the contri-bution analysis,a transfer path optimization scheme is proposed,which may provide a reference for the optimization of the transfer path of metro vehicles in the future.
