摘　　要：为分析自行式高空作业平台臂架的动态特性和结构性能,使用ADAMS软件建立了曲臂结构的动力学模型,对曲臂中各部件进行了全行程的运动仿真分析,得到了关键铰点及各油缸的承载特性曲线。接下来,以伸缩臂为例,使用ANSYS软件进行了结构性能的计算,臂体套接部位的最大应力为363MPa。最后,对首台样车进行了场地试验测试,包括过载测试、压力测试和应力测试。结果表明:臂架各部件动态运动平稳,实测伸缩臂套接部位的最大应力为317MPa,在过载工况下的安全系数达到了2.16。In order to analysize the dynamic charaeteristic and structural property of the articulated booms in the self- propelled aerial work platform （SAWP）, dynamic models of the articulated booms were made by software ADAMS On the basis of dynamic models, the kinematics simulation analysis of the articulated booms were done. Next, the telescopic booms were calculated by software ANSYS, and the results showed the maximum stress of the telescopic booms was 363 MPa Last, the prototype field tests including over-load test, pressure test and stress test were done and the results showed the dynamic motion of the articulated booms was stable, the actual maximum stress of the telescopic booms was 317 MPa, and the safe coefficient in over-load condition was 2.16.
