3D Virtual Simulation of Beam Pumping Unit Motion Based on Inverse Kinematic

Article Preview

Abstract:

The movement of beam pumping unit is a kind of involute moment. The exiting virtual reality engines provide translation, rotation and zooming, which belong to the category of the forward kinematics. It is difficult to simulate the beam pumping unit movement based on forward kinematics. The paper first analyzes the motion rule of beam pumping unit, and then introduces the forward kinematics method (FK) and the inverse kinematics method (IK).According IK, the paper establishes the motion model of beam pumping unit, in the motion model the donkey head is seen as the end effector.The paper finally realizes 3D virtual simulation of beam pumping unit motion based on IK. The method of using IK to simulate the motion of beam pumping unit is is proved to be correct by contrasting the simulation results between using FK and IK.
