Optimal design of clamping mechanism for AUV underwater docking device based on Kriging model

摘要

In this paper, the clamping mechanism of AUV underwater docking device is optimized. The four parameters of the clamping mechanism are designed by orthogonal test. The finite element software ANSYS is used to solve the mass and equivalent stress. And the Kriging model are used to fit the response surface model. Under the premise of satisfying the maximum equivalent stress and the maximum deformation, the minimum mass is obtained by using the multi - island genetic algorithm and the large scale generalized reduced gradient. Finally, the mass of the clamping mechanism is reduced by 35.3%.
