Computer-Aided Design of Compliant Micro-mechanism with Multi-objective Topology Optimization

The proposed optimization method is based on minimizing the structure compliance and maximizing its output displacement,and the corresponding topology optimization model is established.A sensitivity analysis of adjoint method is presented to analyze the topology optimization problems.Meanwhile,the globally convergent version of the method of moving asymptotes （GCMMA） is used in the optimization algorithm.Two numerical examples verified the effectiveness of this approach.
