Abstract For the problem of optimal fixture layout design in discrete point set domain, this paper proposed a topology optimization method. A penalized spring contact model was presented. The spring densities of the candidate contact points were introduced as a set of design variables. The objective is to minimize the deformation of the workpiecefixture system. The implementation of the algorithm and numerical examples were also presented. The results show the effectiveness of the proposed method for both 2-D and 3-D cases.
