Optimal design for sealed cabin of underwater high-speed photography system

摘要：

To achieve the lightest weight of the sealed cabin of the underwater high-speed photography system, optimal design is introduced into the design for the sealed cabin. By detailed analysis of geometric character and work condition, the finite element model represents the structure of the sealed cabin are set up. The result shows that the sealed cabin has the lightest weight when the thicknesses of cylinder and end board are 4.05mm and 23.66mm respectively. A new method is put forward to determine the proper range of element size, i. e. optimal design method. The new method can be utilized to verify the reliability of simulation result. The problem of determining element size is solved. This new method is very useful in finite element analysis.
