Haikun Wen, Bozhong Gu, Xuefei Gong

Dome A is the highest location in the Antarctic inland and it is one of the best locations for the astronomy in the world. Now the Dome A has a telescope (the first Antarctic Survey telescope) and the second and the third one is designed on the base of the first one. The Mechanic design is the basic part of the telescope, studying it can improve the quality of the telescope. Firstly, the paper introduces the optic design of the telescope, secondly the structure of the primary mirror system and the modal of the tube of the second telescope are calculated and some test of it is also introduced. Thirdly the paper introduces the other mechanic design of the second and third telescope, compares the difference between these two telescopes.
