In this study, we try to design a shock absorbing structure using the compliant mechanism. To design the shock absorbing structure, it is necessary to consider the plastic deformation. We use the elastic-plastic body to design the compliant mechanism. First, we do topology optimization whose object function is to design the shock absorbing structure and the compliant mechanism. In this topology optimization, we use Evolutionary Structual Optimization. And we investigate the shape and the characteristic while the parameters fluctuation. Secondly, the impact test is done to confirm whether it is functioning as a shock absorbing structure. We test two models and compare the behavior of each model.
