| 摘 要： | 应用ADAMS动力学仿真软件,建立了某三轴重型车辆的多自由度整车仿真模型,分析了车辆在不同路面工况下行驶和车辆以不同载重、不同速度行驶时,对路面的动荷载作用。研究结果表明:在车辆的行驶速度范围内,车辆对路面的动荷载随着车速的增加而增加;随着路面振幅的增加而增加;且在相同条件下,满载车辆较空载车辆对路面的动荷载要大很多。

| Abstract: | Model of heavy truck was built with the ADAMS dynamics simulation software.Dynamic loads between the wheels and the pavement with different loads and different speeds and different road surfaces were analyzed comparatively.Result indicated that in vehicles moving speed range,dynamic loads between the wheels and the pavement increase with the speed increasing;dynamic loads between the wheels and the pavement increase with the pavement amplitude increasing;Under the same conditions,the dynamic loads of fully crewed vehicles was larger than no-load vehicles. |
