【Abstract】 The optimal design of composite structures of principle bearing cylinder in large scale communication satellites is performed with JIFEX software.The constraints on structural vibration frequencies and buckling stability are taken into account,and several kinds of design variables are optimized.Particularly,the material of honeycomb core is optimized as discrete variable with a continuing treatment method.Multiple models of design optimization have been solved and compared each other.The design optimization results propose some conclusions to guide the design.更多还原
