Numerical Simulation of Railway Track Irregularities Based on Stochastic Expansion Method of Standard Orthogonal Bases

Abstract:

A new simulation method of stochastic process was accepted in the field of simulation for the track irregularities. This method adopted the Hartley orthogonal bases as the standard orthogonal bases. On the basis of the expansion method of stochastic process, and under the condition of ensuring accuracy, it could capture main probabilistic characters of a stochastic process with only a few independent random variables. Through the numerical simulation of the example, it testified the validity and effectiveness of the new method.
