摘要
根据500m口径球面射电望远镜(FAST)设计方案,基于系统动力学建模方法,建立了馈源支撑系统的机械模型。采用此模型进行了拖动状况下系统的动力响应分析,研究了不同拖动速度及阻尼索各种阻尼取值下馈源的动力响应。同时对拖动扰动及风载荷的对系统响应的影响情况进行了对比分析。
According to the design of Five-hundred-meter Aperture Spherical Telescope （FAST）, the mechanical model with flexible rope of the feed supporting system was established based on the multi-body system dynamics modeling methods. Dynamic response was studied under various the dragging speed and different damping values of rope. The influence on the system under dragging disturbance or wind load was also analyzed to contrast different situations. The result may provide a good reference for the final choice of the project.
