The vibration response and acoustic radiation of composite structures under external loads are studied. On this basis, the structure-acoustic radiation optimization design model of composite material is analyzed, and the structure of symmetrical composite material plate structure is analyzed based on genetic algorithm - geometry optimization analysis of acoustic radiation. The numerical examples show that the optimization of parameters such as the number of plies, the thickness of ply and the angle of ply can effectively reduce the vibration and acoustic radiation of the structure. Numerical examples show the effectiveness of the optimization method.
