Abstract Solidworks is a comprehensive part and assembly modeling capabilities of 3D design software, the software which is easy to use uses a Windows graphical user interface.The main purposes of the subject of the power boxes are that sheet metal modeling study of sheet metal features of Solidworks software modeling capabilities with its plug-in Solidworks and the Simulation Finite Element Analysis to optimize the design of the structure of the power supply box, so that the power supply box which is in the lightweight and low-cost basis to achieve higher strength and stiffness.a power box consists of mounting plate, the surrounding framework and on the flip-style cover which connected with a fixed spot or screw , Power Box is a submarine power supply, control and distribution equipment, and it is particularly important to submarine.

The topic for the power supply box cover is putting forward adjustment program by changing its slotting depth, material thickness, flanging and other factors.Finite element analysis of the structural performance of the various options, select the best program, and summarizes the impact of various factors on the structural performance.

Keywords:Solidworks; Sheet metal modeling; Power Box; Finite Element Analysis
