Numerical Simulation Method of Track Irregularities Based on Secondary Filtering

Abstract:

Track irregularities are the only external excitation in vehicle-bridge coupling vibration analysis and therefore the numerical simulation method of track irregularities is very important. The U.S. frequency spectrum is usually employed to simulate the track irregularities in China. In this paper, the secondary filtering method is introduced to the simulation of track irregularities and MATLAB programing is employed to simulate an example. Based on the comparison of the simulation results and the objective function, it is indicated that the simulation result is reliable and the method is feasible.
