一种双层浮筏式南极望远镜运输减振方案设计

Dome A是南极内陆距海岸线最遥远的一个冰穹,具有极为重要的科考价值,但是从上海中国南极科考基地出发前往Dome A的道路振动加速度值十分巨大。首先,分析了从上海到南极的运输振动环境,确定了从南极泰山站到Dome A为重点的缓冲包装的关注范围,并提取了该区间测得的最大加速度值;其次,以南极巡天望远镜主镜室为包装减振对象,设计了一套双层隔振的浮筏式减振系统用于南极内陆地区的运输,根据相应的最大振动加速度值确定了减振系统的相应参数;最后,对其进行了静力学和动力学的模拟分析。2013年冬季在中国漠河地区进行了减振系统的运输实际测试,测试结果显示,该套系统可以满足南极巡天望远镜主镜的运输安全需求。

Double Layer Floating Raft Vibration Attenuation System for Antarctic Survey Telescope Transport

Dome A is the most remote region from the coast of the Antarctic, but it has a very important scientific value. The vibration and shock acceleration from Shanghai to Dome A is much larger than the ordinary road. The paper proceeds as follow: Firstly, the vibration acceleration from Shanghai to Dome A is introduced, and the largest location range is determined as the focus of the package cushioning design system. Secondly, a double layer floating raft vibration attenuation system is designed, and the parameters of the system is designed according to the vibration environment. Also the statics and dynamics analysis of the system is showed. In the winter of 2013, the actual test of this system has been done in MoHe China. The test results show that the system can meet the transport safety requirements of the telescope mirror.
