摘要

According to flexible connectivity of space stabilization system, This paper proposes the finite element analysis method using multiple equivalent spring connecting unit to replace the original flexible connections. And the elastic coefficient's correspondence between the equivalent spring and the original spring were deduced. Using the equivalent spring method, the tip/tilt mirror system for finite element modeling is completed, After completion of the modal analysis, first-order resonant frequency is calculated. At last, the tip/tilt mirror system is tested in non-contact laser resonance detection system, And test results and modal analysis results were compared, and results show that the finite element modeling method of using equivalent spring connecting is effective. Provide constructive reference for subsequent tip/tilt mirror design, has a very important reference for similar projects.
