Research on Topology Optimization Based on Interval Sensitivity Analysis Method

Abstract

Abstract:

Characteristics of interval sensitivity analysis method were studied and feasibility of introducing interval sensitivity analysis method to topology optimization of bound constrained was analyzed.According to the merits of interval analysis and shortcomings of
traditional sensitivity analysis,a topology optimization method of moving sub-interval
center method was established.The feasibility and validity of the method was verified
by a numerical experiment.

Key words: interval, topology optimization, sensitivity analysis, sub-interval center moving method
