Abstract With the development of modern military technology and improvement , the applications of shipboard equipment is extremely wide , its plays a crucial role in the normalization of the ship to meet the needs of traveling at sea. Shipboard power box is a powered device for the ship, it is made to provide electricity for all the electrical equipment on the ship , so the power box on the ship shipboard operation play an important role.This research is the structure design of shipboard power box , first the power box has a preliminary structural design concept, the program selection of the main frame design, the selection of materials, the method of connection between the various components and the selection of processing method . Then use three-dimensional modeling solidworks for sheet metal structures, draw out the three-dimensional sheet metal parts for power box, and the based on finite element analysis is conducted to optimize the design, and then draw a good three-dimensional parts for assembly, use Solidworks Simulatio assembled power supply box on an overall structure modeling, modal analysis and optimization.Finally,the sheet metal structure and thermal aspects are need to be improved, making the design of the power box in structure and function meet the design requirements.

Keywords: Shipboard equipment; electrical output; structural design; finite element analysis and optimization
