Kinematics Analysis of Mine Mounted Mechanical Arm Based on D-H Parameter Method

随着煤矿智能化进程的不断推进,煤矿机器人的研发引起了科研人员的关注。由于井下作业空间受限、视线较差,使煤矿机器人的研发受到了制约。针对一种矿用车载机械臂展开分析,利用三维软件构建重载机械臂的三维模型,利用D-H参数法建立机械臂运动学模型,完成了机械臂执行端的运动学推导,然后用Monte Carlo法对车载机械臂模型的运动空间进行求解,为密闭空间内矿用车载机械臂的动力学及运动学分析提供了一定研究依据。

With the continuous advancement of the intelligent process of coal mines,the research and development of coal mine robots has attracted the attention of scientific researchers.Due to the limited working space and poor vision,the research and development of coal mine robots has been restricted.Analyzed a kind of mining vehicle mounted mechanical arm,used 3D software to build a three-dimensional model of heavy-duty mechanical arm,and used D-H parameter method to build a kinematic model of the mechanical arm.The kinematics derivation of the actuating end of the mechanical arm was completed,and then the motion space of the vehicle mounted mechanical arm model was solved by using Monte Carlo method,which provides a certain research basis for the dynamics and kinematics analysis of the mining vehicle mounted mechanical arm in the confined space.
