Abstract:

The traditional design methods to draw the envelope diagram have many shortcomings , such as the heavy workload, imprecision and less intuition .Pro/E software was used to model and assemble for backhoe working equipment of the hydraulic excavator .Above all, the excavator movement process and work conditions were analyzed.Then mechanism kinematics simulation was carried on by Mechanism module in the Pro/ E software.The limit positions of movable arm , bucket arm and bucket were found through setting joint shafts of the excavator .At last , the envelope diagram of the top end of excavator bucket was obtained.The results of motion simulation can be not only shown in form of cartoon, but also output in form of parameters .So the working parameters of the excavator are obtained .It can be know n whether the components interfere and whether excavator design satisfies the performance requirement .Dynamic simulation provides design references for improving over all performances .

摘要： 　采用传统的运动分析方法绘制挖掘机铲斗包络图存在工作量大、不精确和不直观等缺点。利用Pro/E 对液压挖掘机反铲工作装置进行了建模和装配, 首先分析了挖掘机的运动过程和各工况位置, 然后用Pro/ E 中的Mechanism 模块进行了机构运动学仿真, 通过对挖掘机各连接轴的设置, 找到挖掘机动臂、斗杆和铲斗的各极限位置, 得到了挖掘机铲斗斗尖运动包络图。运动仿真的结果不仅可以以动画的形式表现, 也可以以参数的形式输出,得到挖掘机的工作参数。这样可知零件之间是否干涉, 还可获知挖掘机的设计是否满足性能要求, 为改善整机性能提供设计依据。
