摘　　要：通过ADAMS软件建立某自行走直臂式高空作业车连杆机构的参数化模型,在主臂上升过程中,以连杆机构的六个铰点位置作为自变量,以工作平台最大加速度作为优化目标函数进行优化与仿真。仿真结果表明铰点位置优化后使工作平台最大加速度减少87.13%。基于优化结果进行试验验证,试验结果与仿真结果相对误差较小,证明了铰点优化后,将大大减少工作平台最大加速度,从而提高了操作人员的舒适性。Using ADAMS software to establish a parametric model of the linkage mechanism of an Self-propelled Telescopic Boom Lift aerial work platform.When lifting the main boom,the six of the linkage mechanism are used as the independent variables,and the maximum acceleration of the working platform as the objective function for optimal design.The simulation results indicates that the maximum acceleration of the work platform is reduced by 87.13%after the hinge position optimization.Testing physical experiment based on optimization results,the test results are basically consistent with the simulation results.Both results reveals that the optimization of the hinge point impoves the operator’s comfort on the work platform.
