路基沉降对低地板有轨电车动力学性能的影响
Influence of Subgrade Settlement on Dynamic Performance of Low Floor Tram
摘要
Abstract
Track deflection induced by uneven subgrade settlement results in rail deflection will ultimately affect the dynamic performance of the vehicle.Based on the theory of vehicle-track coupled dynamics,an vertical coupled dynamics model of tram track with settlement of subgrade is established in this paper,as well as influence of subgrade settlement on the dynamic performance of low floor tram is studied.Results show that,the subgrade settlement obviously increases the vibration of the tram system.Amplitude and wavelength of uneven subgrade have both effect on vehicle vibration,rail displacement and wheel-rail force.Vehicle dynamics is enhanced when decreasing the amplitude or increasing wavelength of uneven subgrade.关键词
