大型射电望远镜馈源体轨迹跟踪系统的力学分析

Mechanical Analysis of the Orbit Tracking Movement of Feed System in Large Spherical Radio Telescope

给出了悬挂重物的悬索系统悬链线的曲线方程及其受力分析,在此基础上,运用作复合运动的刚体的运动学和动力学的方法,对大型射电望远镜的馈源系统进行了力学分析及馈源体轨迹跟踪运动的控制研究,给出了控制馈源体轨迹跟踪运动的方法及步骤.算例验证了理论及方法的正确性、可行性.

The curve equation and its mechanics analysis of suspended-cable under the condition of end load are given. Then on the basis of it, the mechanical analysis of suspended-cable system for large spherical radio telescope is studied, procedures of the control for the orbit tracking movement of the line feed in large spherical radio-telescope are given. The validity of the results mentioned above is confirmed by means of computer simulations.
