Paper Abstract

Based on the analysis of mechanical structures and characteristics of several shafting reflecting mirror at home and abroad, the composition principle of FSM is introduced in detail, and a concrete designing scheme of shaftless FSM is proposed. Using resonant frequency as a starting point, according to elastic mechanics, a vibration system of FSM is established. The structure of elastic system of FSM, material, manufacturing and heat treatment are also introduced. The computer simulation of the structure is completed by using COSMOS software. At last, the corresponding experimental result of property of open-loop of FSM is also given.
