大型射电望远镜类Stewart平台的奇异性研究
Research on the Singularity of Resembling Stewart Platform of a Large Radio Telescope
摘要
Abstract
The cable-cabin system of a large radio telescope has resemblanceto Stewart platform. The feed cabin is drawn with six cables to trace an object as if Stewart platform is drawn with six legs to manufacture a part. Considering flexibility of the long cables, the realized workspace is analyzed. Based on the nonlinear static equilibrium equations of the system, the force singularity is described by the determinant and condition number of the Jacobian matrix clearly. The singularity may be eliminated according to the research in future.关键词
