| Abstract (English): | Aiming at the phenomenon of excessive torque during the motion of electric cylinder on 3-RPS platform’ a new type of three degree of freedom parallel plat form with anti-twist structure was designed’ which is applied to the virtual reality technology. Its kinematics and anti twist performance were studied. The model of Anti-Twist structure parallel platform in Solid Works was built’ and its inverse kinematics and positive solution was analyzed’ combining with ADAMS and MATLAB software to verify the correctness of inverse solution algorithm. Based on inverse solution algorithm’ by using inverse solution iteration method to approaching position positive solution’ the anti-twist performance of electric cylinder with anti-torsion structure and 3-RPS platform was simulated by using ADAMS. The two kinds of electric cylinder of three degrees freedom of platform in the motion process of the torque were compared and analyzed. The research results show that the torque of electric cylinder with anti-twist structure is significantly reduced. Provides a practical basis for the platform structural design.

| Abstract (Chinese): | 针对3-RPS平台电动缸运动过程中受扭矩过大现象,设计了一种应用于虚拟现实技术中的具有防扭结构的新型三自由度并联平台,对其运动学和防扭性能进行了研究.在SolidWorks中建立了防扭结构并联平台模型,并对其进行了运动学逆解和正解分析,联合ADAMS和Matlab软件对逆解算法进行了验证,在逆解算法的基础上,采用反解迭代的杆长逼近法近似求解了位置正解.应用ADAMS对具有防扭结构平台和3-RPS平台电动缸的防扭性能进行了动力学仿真,对比分析了两种结构下电动缸在运动过程中所受扭矩.研究结果表明:具有防扭结构的运动平台的电动缸受扭矩明显减小,为平台结构设计提供了实用依据.
