利用拉格朗日第方程对液压挖掘机的工作装置建立了挖掘作业过程中的动力学模型,对其动能、势能和挖掘力进行计算,为分析挖掘作业工作装置所受到的力和运动之间关系、控制作业规划和仿真提供了理论基础。
The Lagrange equation is used to establish the dynamic model of the excavator during its operation. The kinetic energy, potential energy and digging force are calculated. In order to analyze the relationship between the force and the movement of the digging working device, Relationship, control job planning and simulation provides a theoretical basis.
