Paper Abstract

This paper describes the optimum solution improving the total quality of the mirror room of the 2-m telescope. Referring to the mirror room with the dimetric truss, a group of reasonable sizes of the mirror room are given by optimization methods and modal analyses, which will improve the resonant frequency by 9.4%. As a result, the mirror room is less likely to resonate. Besides, the static module and dynamic response module in ANSYS are utilized respectively to analyze the mirror room deformation caused by gravity, the modal analysis and the vibration response. By the calculation of ANSYS, finite element analysis(FEA) method proves that the performance of the mirror room is greatly enhanced by means of optimum design.
