【摘要】 介绍了大射电望远镜光机电一体化设计方案 ,根据贵州KARST地貌的地理位置推导了线馈源的扫描运动轨迹 ,由悬链线方程得到了悬索挠度与索张力的求解方法 ,并对六悬索并联索系结构进行了运动学描述和分析 ,提出了悬索长度控制实时性问题的解决办法 ,最后给出动态检测时悬索末端坐标的计算式
【Abstract】 This paper introduced the integrated optic mechanical and electronic designing scheme for large radio telescopes.The scanning motion track of linear feedback was deduced according to the geographical position of landforms of Guizhou KARST area.The method of solution for cable’s deflection and tension were obtained from linear equation of suspension chain.The kinematics description and analysis were carried out upon structures of six suspension cabled parallel cable system.The solving means of real time problems for controlling the lengths of cable were advanced.Finally the formulae of cable tip coordinates in dynamic test have been given out.
