Multi-objective Topology Optimization of Piezoelectric Smart Continuum Structures with Interval Parameters
摘要
Abstract
Multi-objective integrated optimization of piezoelectric smart continuum structures with interval parameters is studied.Based on non-probabilistic reliability,the integrated optimization mathematic model with stress and voltage constraints of piezoelectric smart continuum structures is constructed,where the upper bounds of the structure weight and the quadratic objective function are taken as objective functions and the structural element topology information,the number and placements of actuators and control gain are regarded as design variables.Through Taylor expansion and interval extension of function,the mean values and deviations of the stress for each element and the voltages for the piezoelectric active element,and the interval of the quadratic objective function can be obtained.The Pareto CMOPGA(genetic algorithm for constrained multi-objective optimization problem) on the basis of individual ranking is adopted to solve the constrained multi-objective optimization problem.The numerical example shows that the proposed method is effective and reasonable.关键词
