Abstract

We designed one 6 degrees of freedom (DOF) parallel platform to track and observe in a certain range according to requirements of a telescope. First of all, considering about the application requirements of telescope, we determined the specific structure. After that we carried on theoretical analysis about kinematics and dynamics of the platform. Then, we build parameterized 3D model and optimized it with Adams software to ensure the platform to achieve best dynamic performance and minimum space size. Finally we did co-simulation making use of Adams and Simulink software (Matlab) to observe the platform’s tracing ability. And we analyzed the factors affecting the tracking error.

六自由度并联跟踪平台的研究
根据望远镜的要求,设计了一个6自由度的平行平台,在一定范围内进行跟踪观测。首先,考虑到望远镜的应用需求,我们确定了具体的结构。然后对平台的运动学和动力学进行了理论分析。然后,我们建立了参数化的三维模型,并利用Adams软件对其进行了优化,以确保平台获得最佳的动态性能和最小的空间尺寸。最后利用Adams和Simulink软件(Matlab)进行联合仿真,观察平台的跟踪能力。并分析了影响跟踪误差的因素。
