Simulation Study of Heavy Vehicle Road-Friendliness under Bilateral Tracks’ Excitation

Abstract:

In order to study the road friendliness of heavy vehicle under bilateral tracks’ excitation, the spatial domain random pavement under bilateral tracks’ excitation was simulated through the second-order rational function power spectral density (PSD) and the harmonic superposition method. A rigid-flexible coupling virtual prototype of the heavy vehicle was established by using SIMPACK software. Then a driving dynamic model of heavy vehicle was established under bilateral tracks’ excitation. The tires loads of the vehicle’s each axle were calculated. The dynamic load coefficient (DLC) and 95 percentage fourth power aggregate force were used as the road-friendliness criterions for studying the road-friendliness of heavy vehicles under bilateral tracks’ road excitation. The research results could provide the basis for the prediction of road friendliness of heavy vehicle.
