Abstract
The Optimization theory of the radio bracket pair was described. The radio bracket pair was optimized by utilizing Altair CAE optimization tools. The FEM model of brackets was established by HyperMesh, the Linear static and vibration analysis was done in OptiStruct. The current radio bracket pair was optimized through topology optimization according to stress and frequency requirements. The results showed that the stress and natural frequency of the radio bracket changed little in comparison with the original design, an amount which was within the allowable engineering parameters, while the cost of radio bracket pair was reduced by 25.0%, two attachment points were removed which directly saved the cost and labor of bolts, and the weight of bracket was lightened about 15.4%
