The Motion Simulation Platform Study Of Three Degrees Freedom Servo-Driven

Parallel kinematic platform has strong application value in the field of simulation,simulation platform necessary part of the semi-physical simulation test, this simulator canalso be used for the development and application of entertainment facilities, theplayerexperience immersive and thrilling feeling, to bring people’s leisure life more fun,the example4D competitive racing and entertainment Jockey. By three degrees of freedomof the mechanical structure of the parallel mechanism, combined with the4D interactivethree-dimensional gaming platform design specifications, determined on the basis of theanalysis of the mechanical characteristics of the platform motion mechanism and kinematiccharacteristics of the executive part of the simulation platform selection and a controlmethod of the system.Three Degrees Freedom parallel mechanism simulated motion platform bodyconstituted by the the three scalable support rod (electric cylinder), motion simulationplatform rotates a translation of a particular position and orientation is achieved bychanging the length of the telescopic support bar. To obtain the sports degree posturemathematical model based on the mechanical structure of the motion simulation platform,through the transformation of the space coordinates, and deduced the inverse kinematicsand kinematics of the three degrees of freedom simulation platform positive solutions.According to its inverse kinematics solution of mathematical formulas, using MATLABsimulation analysis of its trajectory, to verify the feasibility of this simulation platform for4D stereoscopic game.This article uses PMAC motion control card to build a control system simulationplatform PMAC motion control card combining parallel mechanism composed of the bodyof the motion control system, built-in PLC module of the application PMAC form ofparallel kinematic synchronization and coordinationprogramming, motion simulationplatform with simple motor function. PMAC-based motion control system can more fullyutilize the computing and processing power of the computer, the more realistic simulationof the effect of the motion simulation platform. In addition, with the continuous development and application of three degrees offreedom parallel robot, I believe that this platform can also be obtained in other fieldsinverted widely used, such as: medical devices, parallel machine tool, robot.
