摘要	Truss-supporting structure was widely used among TMA space camera of large or middle size, and how to improve its dynamics characters was the key to the study of cameras alike. As to the design problem of truss structure, bring forward a method of ascertaining the position of the trusses via integrated optimization, study the influence of position variables of the trusses on dynamics characters via designed of experiment, analysed the characteristic of its resolution space. In order to realize whole-space optimized designed of truss, used multi-island genetic algorithm to find the bested resolution, with the objective of improving the 1st-frequency. Used FEM method, find the 1st-frequency of optimized design was 107.72 Hz, which was 29% improved compared with original design (83.45 Hz). The integrated optimization modeling and the analysis method in this study offer a new way for the design of truss structure. 2015, Editorial Board of Journal of Infrared and Laser Engineering.
