System and method for optimizing structural noise uncertainty

Abstract

Provided is a system and a method for optimizing structural noise uncertainty. The system comprises a system framework program and five sub-modules, namely, structural acoustic characteristic deterministic analysis module, structural acoustic characteristic uncertainty analysis module, structural noise certainty optimization module, structural noise uncertainty optimization module and post processing module. By the aid of the method, structural noise uncertainty optimization design is achieved on the basis of deterministic analysis and uncertainty analysis of structural acoustic characteristics. The method integrates an optimization model of solving an uncertainty problem and various algorithms in the system, and provides a convenient tool for non-professionals to conduct structural noise uncertainty analysis and optimization.
