Abstract

LAMOST is a kind of special reflecting Schmidt telescope which solved the problem to achieve both wide FOV and large aperture on one telescope. This feature makes it competitive to do the large sky area survey work. According to the configuration, the focal plate of this kind of telescope will perform three main motions: derotation, tilt and focusing. Normally the focal plate will be supported at a certain height above ground. China has launched the astronomy research at Antarctic Dome A and planned to set up a LAMOST-style telescope there. Considering the harsh environment and terrible remote transportation, a kind of simple and compact support structure of focal plate is proposed in this paper aiming at light weight, easy installation and easy adjustment, based on the review of LAMOST experiments. The calculation and simulation results show that the compact support structure can meet the system requirements.
