[Abstract]:The purpose of structural optimization is to make structural use of materials more economical and force distribution more reasonable. Topology optimization is the most important aspect of structural optimization research. The improvement of the structure topology can greatly improve the performance of the structure or reduce the weight of the structure and bring direct economic benefits. In recent years, topology optimization has become a hot topic at home and abroad. At present, the topology optimization is due to the particularity and complexity of its algorithm. Its description, model and theory are still in the exploratory stage, and are less used in the design of compliant mechanism. Flexible mechanism is a kind of elastic deformation of the member itself to output all or part of the motion. At present, the pseudo-rigid body model is mainly used to analyze and design the compliant mechanism. This paper attempts to use the topology optimization method to design the compliant mechanism. A new algorithm developed by ourselves is adopted. There is a large deformation in the compliant mechanism. Therefore, the nonlinear finite element numerical method is used in this new algorithm. In this paper, the compliant pliers and compliant constant force mechanisms are designed by using the new algorithm of topological optimization. The results show that the new algorithm can be used to optimize the topology of compliant mechanism.
