摘要
Stewart平台由于其容易实现六个自由度的特性,被广泛应用于飞行模拟器和大型车辆驾驶模拟器中,以实现驾驶的体感模拟。目前应用较为广泛的Stewart平台有实心平台和中间镂空平台两种基本结构。采用有限元分析的方法,对两种典型结构进行力学特性分析,为后续的结构设计提供数据;并采用有限元分析软件ANSYS,对两种典型结构进行数字化仿真,找出Stewart优化设计依据,最终得出优化设计方案。
Stewart platform ,due to its characteristic of easy to realize six degree of freedom ,is widely used in aircraft simulators and large vehicle driving simulators .It can realize the proprioceptive simulation of driving .Currently ,there are two typical structures of the movable platform ：the solid model and the hollow model .This paper will adopt finite element method to analyze the two models . Through building 3D model ,digital reconstruction ,analyzing in ANSYS ,we will come up with an optimal design of the platform .
