摘　　要：为了分析自行式高空作业平台作业过程中的动态稳定性,以数学模型为基础,采用ADAMS软件建立整车的动力学仿真模型,对6种最危险的作业工况进行仿真计算,得到不同工况下各轮胎承载的载荷特性曲线及整车动态稳定性的安全系数。最后,进行场地试验测试。研究结果表明:测试数据与仿真计算数值间的极值相对误差最大为13.4%,试验测得动态稳定性的最小安全系数为0.123,验证了整车在作业过程中具有良好的动态稳定性,也验证了对自行式高空作业平台使用动力学仿真和试验测试相结合的分析方法的正确性和准确性。In order to calculate the dynamic stability of the self-propelled aerial work platform(SAWP)at work,the analysis method based on mathematical model and dynamic simulation model of the SAWP was put forward.Then the dynamic simulation model of the SAWP was made with software ADAMS.Six kinds of the most dangerous working conditions were analyzed,and then the dynamic load curves of tires and dynamic stability safety coefficient were obtained.At last,the dynamic stability of the SAWP was verified by the field experiment.The results show that the maximum error between test data and numerical simulation calculation is13.4%,and the dynamic safety coefficient is0.123.So the dynamic stability of the SAWP at work is satisfied.At the same time,combining dynamic simulation and test analysis method of the SAWP is proved in terms of correctness and accuracy.
