摘　　要：为解决高空作业平台的液压自动调平系统产生的设计性角度误差问题,设计之初对调平系统进行了整体优化。自动调平系统产生的误差过大,会影响操作人员的工作舒适度与安全。因此,建立可调整的数学模型来模拟实际产品可能产生的角度偏差,对优化整体的结构设计具有重大意义。采用几何位置的分布、工作斗的重量以及额定载荷作为输入变量,建立主动油缸数学模型移动轨迹与从动油缸几何移动轨迹的相关线性轨迹。通过构造的模型进行迭代优化,在设计期望范围内获得可最佳的轨迹与几何分布。In order to solve the design angle error caused by the hydraulic automatic leveling system of the high altitude platform,the whole leveling system was optimized at the beginning of the design.The error caused by automatic leveling system is too large,which will affect the comfort and safety of operators.Therefore,it is of great significance to establish an adjustable mathematical model to simulate the angle deviation which may occur in the actual product for optimizing the whole structure design.Taking the distribution of geometric position,the weight of the working bucket and the rated load as the input variables,the linear trajectories of the moving track and the geometric moving track of the driven cylinder are established.Through the iterative optimization of the constructed model,the optimal trajectory and geometric distribution can be obtained in the desired range of design.
