摘要
Abstract
Based on the vehicle-track coupled dynamics, this paper establishes the metro vehicle-monolithic track coupled dynamic model. The dynamic responses of metro vehicle-track system are analyzed respectively with dynamic vibration absorber ( DVA) installed on rail and without. Then, the car-body acceleration, wheel-rail interaction forces, rail acceleration and track acceleration are compared with and without DVA, which provides guiding references for the application of DVA on rail. The comparison is conducted in time domain and frequency domain respectively. The results show that DVA has only a little influence on the car-body acceleration and the wheel-rail force decreases with DVA from the point of vibration in time domain. The rail and track accelerations decrease remarkably around the pinned-pinned frequency. The calculation indicates that the installed DVA is beneficial to the reduction of vibration and noise of rail and to the wheel-rail interaction forces.关键词
