| 摘 要： | 针对LAMOST反射施密特改正镜的特殊防护及功能要求,经多种方案设计和实验,最终设计和制造了一套新型轻质帘式镜罩系统,并得到了成功应用。首先回顾LAMOST反射施密特改正镜镜罩的功能要求,以及镜罩的样机实验和方案遴选;详细介绍最终选定的新型轻质帘式镜罩系统的具体机械结构、电气控制方法以及现场安装调试等研究设计工作。该新型镜罩主体功能件为轻型布帘罩体,两侧各通过一组滑块联接于两根平行的弯曲C形轨道,并由2组4只电机通过拉线的方式实现电动开闭;为允许反射施密特改正镜可转至竖直位置,轨道的末端采用电动推拉实现弯折,以避免结构干涉。该镜罩已在LAMOST望远镜上投入正常运行,安全性得到了考验和确认。

| Abstract: | Based on various designs and tests a novel lightweighted curtain-type design of cover has been successfully implemented to meet the requirements of special protection and functions of the LAMOST reflecting Schmidt plate.In this paper,we first review the technical requirements for the cover.Before the final design is adopted,we investigated two prototypes of covers.Our subsequent work has been focused on the mechanical design,electronic control,and on-site installation/debugging of the cover of the novel des... |
