The Structural-Acoustic Optimization Analysis Based on Material Selection Optimization Approach

Abstract:

The problem of application of the material selection optimization approach for structural-acoustic optimization is investigated. By introducing the stacking sequence hypothesis of metal material, the mechanical parameters of the material and plies number are defined as design variables; the mathematical model of material selection optimization for reducing acoustic power is established. Take a hexahedral box structure for example; the material selection optimization is carried out. The example shows that the vibration and acoustic radiation of composite laminated can be reduced by using material selection optimization method.
