一种快速得到挖掘机挖掘包络图的新方法

A new method to get excavator digging envelope diagram rapidly

挖掘机工作装置作业由三个油缸复合动作及铲斗和土石方的相互作用实现。利用虚拟样机技术,对工作装置作业过程进行运动仿真与动态显示,使得设计人员在设计阶段就可以看到其设计方案的合理性、机构参数设计是否最优。基于这种实际情况,应用Matlab软件中的SimMechanics,介绍一种快速得到挖掘机挖掘包络图的方法。准确快速的分析工作装置的基本挖掘尺寸,如最大挖掘高度、最大挖掘深度、最大挖掘半径、最大水平挖掘半径。通过实例可以看出,该方法工作量小,简单快捷。

The work of the mechanism is completed by compound action of three fuel tanks and the interaction of earth moving. Through the movement simulation and the dynamic display of working a new plan of design, make the designer see the dynamic pictures of the equipment working during the course of designing, and verify the rationality of this scheme, the optimization degree of the equipment＇s parameter. According to the reality, introduced a method which can rapidly get the digging envelope diagram of a excavator by employing the SimMechanics of Matlab. Accurate and rapid analysis of the basic mining size can be got, such as the maximum digging height, maximum digging depth, maximum digging radius and maximum radius of the level of digging. The simplify and superiority of this method is verified by practice.
