Motion Analysis and Simulation of 3-DOF Motion Platform with Anti-Twist Structure

Taking the three-degree freedom parallel robot as research subject,a parallel motion platform with anti-twist structure is designed,and its application in car driving simulator is explored. A parallel motion platform of virtual prototyping is established by inventor software and ADAMS software is used to do motion analysis and simulation. The positive and inverse kinematics and dynamics analysis of the platform under the complex motion conditions are completed to obtain the motion characteristics of the platform and achiev a contrastive analysis result about the impact of anti-twisting arm structure on the platform's dynamic performance. A reference for structural design and motion control of the platform is provided and its application in terms of car driving simulator is explored. Physical prototype experiments show that the parallel platform can accurately simulate car driving process and motion state. And because of low cost,rapid response and highly precise movement,the parallel platform has large application value.
