Paper Abstract

This article takes a kind of special supporting structure of deformable mirror as an example to make deeply study on its optimal design and validity simulation based on finite element analysis. The original resonance frequency and modes shape of the supporting structure are obtained with the FEA method and the dynamic theory. Then a group of optimized structure parameters are determined with the BP networks and Genetic Algorithm optimal methods. The simulation analyses including random vibration, harmonic response and fatigue life are carried out to demonstrate that the dynamic stiffness of the optimized supporting structure has been improved greatly by the presented optimization method.
