The Innovative Design Of Clamping And Positioning Mechanism Based On Topology Optimization

With facing the increasing complexity of working conditions and having higher requirements of comprehensive performance to product,traditional design methods can not be applied to modern product design. More and more scholars and engineers favor the structural design method based on topology optimization. In recent years, a variety of topology optimization solving models proposed has greatly contributed to the development of topology optimization technology.This article describes the development of topology optimization technology and the design process of topology optimization. This article studies the solving models and methods of topology optimization such as Homogenization method, SIMP and other methods. According to the topology optimization process, we studied the innovative design of clamping positioning mechanism based on topology optimization as the displacement was optimization goal and the volume fraction was the constraint. The models with different aspect ratios and different angles with the load have been made the circulation of topology optimization. And then we got the influence of two different parameters on deformation and stress of clamping positioning mechanism. Then we selected the appropriate parameter to make a innovative design based on topology optimization for the clamping and positioning mechanism of a offshore platform. Considering the possibility of process and manufacturing, we make a new three-dimensional model design to the clamping and positioning mechanism. Considering the two conditions of pulling and under pressure of the clamping and positioning mechanism, we took a finite element static analysis of the new model. According to the static analysis, we got the final design of the clamping and positioning mechanism.
