Motion Simulation And Control Research On3-DOF Motion Platform

With the development of virtual reality technology, multi-degree of freedom motion platforms is widely used in motion simulation systems. The common-used motion platforms with multi-degree of freedom are parallel mechanism and series mechanism. The parallel mechanism is the favor of many researchers because of its high stiffness, high load carrying capacity and running accuracy, but there is less research on the series mechanisms.This thesis analyzes the typical3-RPS parallel mechanism using the forward and reversed kinematics analysis to the typical3-DOF parallel mechanism. Moreover, a3D motion simulation visualization program is written with the help of VC++and OpenGL library. Users can dynamically modify the relevant parameters for the corresponding simulation in the program to view the forms of motion. The simulation theory offers a method to control the movement of the mechanism, and the simulation result can provide many real reference data.The motion control of the series mechanism is also analyzed in this paper. The prospective motion control method and track-style motion control method are put forward based on the MPC2810motion control card and the virtual entertainment system, and the actual motion control is completed with track-style motion control method and achieved a good result. The simulation of the MPC2810motion control function provides a possibility to write motion control program in a virtual environment and avoids the real machine debugging damage and accidents that may occur, leading to a high efficiency.
