Structural-Acoustic Optimization of Laminated Composite Structures Based on Response Surfaces Method

Abstract:

Based on Mindlin first order shear effect plate theory, the structural-acoustic optimization of laminated composite structures under external loading was investigated. For improving the optimization efficiency, the response surfaces method (RSM) is introduced, and the uniform Latin square method was used to select the most appropriate sample points. In the end, taking the laminated composite plate acoustic radiation as an example, the mathematical model of structural structural-acoustic optimization is established. The results show that the acoustic radiation of laminated composite structures can be reduced by optimizing the stacking sequence parameters such as layers thickness and layers angle. The results prove the validity of the calculating ways.
