Design and Optimization of Compliant Revolute Joint Based on Finite Element Method

Abstract

In this paper, compliant revolute joints after topology optimization are reconstructed, and the finite element modeling of the reconstructed geometric models are carried out by ANSYS. A series of optimized compliant revolute joints are applied the boundary constraint to their external circle and tangential force is applied to their inner hollow circle by ANSYS to make the compliant revolute joints spin in the clockwise/counterclockwise direction. Then, displacement and stress of the compliant revolute joints are analyzed respectively. The results show that these structures after being optimized can achieve greater deformation than the initial one, which can meet the demand for large angle in the engineering applications. Simultaneously, the technology of 3D printing is used to fabricate the compliant revolute joints and the designed experimental program is proposed as well. Thus, the models which designed in this paper not only save materials but also improve the performance, which have a certain guiding significance in engineering applications.
