Abstract
To study the dynamic response of pavements under vehicle-road coupling force, based on the improved sinusoid superposition method, the three-dimensional stochastic road in spatial domain was put forward from two-dimensional road. The three-dimensional stochastic road model was generated by M at⁃lab, and a virtual prototype model of heavy dump truck was established by using ADAMS software. The normal tire force, longitudinal tire force and lateral tire force of each axle were computed when the truck model driving on three-dimensional stochastic road under the velocity of 60 km·h-1. The results indicate that under the excitation of three-dimensional stochastic road, the normal tire force of each axle fluctuates around static load curve, the longitudinal tire force and lateral tire force of each axle alternate from posi⁃tive to negative. The results provide a reference for the future analysis of the pavement response under the action of the heavy dump truck.关键词
