Non-stationary random vibration of a coupled vehicle–slab track system using a parallel algorithm based on the pseudo excitation method

A parallel algorithm based on the pseudo excitation method (PEM) is applied to investigate the non-stationary random response of a vertically coupled vehicle–slab track system subjected to random excitation induced by track irregularity. The vehicle is simplified as a multibody system with 10 degrees of freedom and the slab track...
