| 摘 要： | 针对车-路系统以及车-路耦合作用的特点，运用ADAMS动力学仿真软件，建立了某重型车的多自由度仿真模型，并利用ADAMS对模型进行了仿真计算，分析了车辆以不同载重量、不同速度行驶于不同等级路面时，车辆对路面的动载荷作用。结果表明：车-路耦合产生的动载作用受路面工况的影响较大，随着路面等级的降低，车辆对路面的动载荷有着显著的增大；在车辆正常行驶速度范围内，车辆对路面的动载荷也随着车速的增加而增大；而在相同条件下。满载车辆较空载车辆对路面的动载荷要大很多，即满载对路面的破坏作用更为显著。 |

| Abstract: | According to the characteristic of coupling vibration between vehicle and pavement,the multi-degree of freedom simulation model of a heavy-duty vehicle was built by using software ADAMS. The effect of dynamic loads of the vehicle on the pavement under the condition of the vehicle bearing different loads running at different speeds on different grades of road were simulated based on the vehicle model and software ADAMS.The result shows that(1) the effect of road roughness on the dynamic load is obvious and t... |
