Multiple Designs Approach for Continuum Topology Optimization

Abstract eng:
Topology optimization can provide creative conceptual designs for industry design in the preliminary design stage. However, the traditional topology optimization approaches focus on searching for one optimal solution which may be invalid due to the refinements of models or the additional design requirements. This paper presents the Multiple Designs Approach (MDA) to get several diverse topology designs, which can reduce the risk of lacking full knowledge of the designs by providing multiple designs. Weighting function is used as the objective function to evaluate the performances of multiple solutions. Diversity function is used as constraint to measure the diversity between different topology solutions.
