新型机器人望远镜的设计目的是在探测设施发出警报后30秒内进行快速目标跟踪。为了实现这一点，将需要安装结构和反射镜的快速建立时间要求。这意味着该结构的设计应具有足够的刚性，以在快速回转操作后的“稳定时间”内达到镜面位置。利用有限元模型进行优化分析，从概念上设计出满足机械性能要求，更重要的是满足NRT科学要求的悬置结构。这项研究的主要目的是确定所需的锁定转子共振频率(LRF)，以便在最小化结构质量和成本的同时，为望远镜的动态性能提供足够的刚性。
The New Robotic Telescope is designed to conduct rapid target follow-up within 30 seconds of an ‘alert’ from survey facilities. To achieve this will require a quick settling time requirement for the mount structure and the mirrors. This means the structure shall be designed to be sufficiently rigid to achieve the mirror position within the ‘settle time’ after a quick slew operation. An optimization analysis using the finite element model is developed to conceptually design the mount structure that meets the mechanical and more importantly the NRT science requirements. The main objective of this study is to determine the required locked rotor resonance frequency (LRF) that provides enough rigidity for the telescope dynamic performance while minimizing the structural mass and cost.
