目前,我国口径最大的2.16米天文光学望远镜的跟踪轴采用了五个静压油垫的支承系统。跟踪轴的微调机构亦采用了静压油垫。现把其支承的结构设计、运行性能以及跟踪轴晃动与油膜厚度变化之间的关系介绍如下。
At present, China’s caliber 2.16 meters astronomical optical telescope tracking axis using five hydrostatic pad support system. Fine tuning of the tracking mechanism also uses a hydrostatic pad. Now the structure of its support design, operating performance and track the relationship between rocking and film thickness changes as follows.
