摘要
设计了一种大型 Stewart型平台用于大射电望远镜 (L T)二级精调 ,通过坐标变换 ,推导出其运动控制的数学模型 ,并利用 Jacobian矩阵 ,进行了动力学分析 ,给出了其运动精度分析结果 ,证明其应用到 L
A new kind of Stewart platform for LT fine tuning is designed in this paper. The mathematical model for kinematic control of the platform is derived through coordinate transformation. Dynamic analysis is carried out with Jacobian matrix and results of kinematic accuracy analysis are obtained. They show that the designed Stewart platform is quite effective for tracing the LT line feed trajcetory.
