| 摘 要： | 采用ADAMS建立了某重型机械传动系统整车结构的动力学模型。针对满载和空载工况下装载机结构系统进行了动态载荷计算,采用多岛遗传算法优化了桥壳载荷分配率。分析了不同车速和工作装置的不同提升高度对车辆动态性能的影响。结果发现,在在不平坦的路面上快速行驶时,对车辆造成的振动较大。通过试验分析了不同作业过程下桥壳所受载荷的动态变化规律和大小,试验数据为装载机的多体动力学分析提供了数据参考。

| Abstract: | The dynamic model of the vehicle structure of a heavy mechanical transmission system was established by ADAMS. The dynamic load calculation is carried out for the loader structural system under full load and no load conditions. The multi-island genetic algorithm is used to optimize the load distribution ratio of the axle housing. The effects of different vehicle speeds and different lifting heights of the working device on the dynamic performance of the vehicle are analyzed. As a result, it was found that the vibration caused to the vehicle was large when traveling fast on an uneven road surface.The dynamic change rule and size of the load on the bridge shell under different operating processes are analyzed by experiments. The test data provide data reference for multi-body dynamic analysis of loader. |
