Structure Optimal Design of the Hydraulic Cylinder in Half-burying-torpedo Device Based on Finite Element Technology

Optimal design based on finite element analysis was introduced into the hydraulic cylinder in half-burying-torpedo device design,and the optimal design was also finished.The optimal design model was built,and calculated using ANSYS.The result of optimal design was gained,and compared to the result of theoretical calculation.It was revealed that the application of optimal design process based on finite element analysis was useful in the hydraulic cylinder in half-burying-torpedo device design.The speciality and force status of the optimal structure were improved.And the engineering demands were well satisfied.
