Design of single passenger underwater vehicle

Nowadays, diving is done for a variety of purposes. One type of diving activity is scuba diving. In the process, time and scuba diving area are limited by the availability of gas for breathing. This research focused on the design of single passenger underwater vehicle frame. Frame is a major component of the underwater vehicle functioning as a holder of the load and a place to put all the components of the vehicle. This research was about design, simulation, and optimism of frame using finite element method. The frame was designed based on the outer shape of the underwater vehicle, the weight, type of material and the efficient manufacture of the frame production. Aluminum Alloy 2024-T3 was the material used in the design. Simulation was done with a load of the pressure distribution received by underwater vehicle body at a maximum depth and speed: 50 meters and 80 m/s. The result of this research was an efficiently strong frame which was secure and ready to be manufactured.
