基于ADAMS/CAR的重载车辆不平路面动载荷仿真分析

Simulation Analysis of the Dynamic Loads on Uneven Road of Heavy-duty Vehicle Model based on ADAMS/CAR

用ADAMS/CAR仿真软件建立了近似实测数据的某车辆模型和路面模型,对车辆在不同路面波形幅值、路面波长、载重和车速下的行车动载荷进行了仿真分析,为分析车辆-道路耦合系统的相互作用打下了基础。

The heavy-duty vehicle model and pavement model based on the measured data were set up by ADAMS/ CAR. The simulation analysis of the dynamic loads of driving was conducted with different amplitudes, different wave- lengths, different loads, and different speeds. The simulation results established basis for analyzing the interaction between vehicle and pavement coupled system.
