Simulation of a lifting control system in sub-mini submarine

This paper summarizes the structure of the ups and downs system and gives a discussion in detail about the influence of speed due to change of structure parameters. The changes directly affect performance as a whole. Hence, structure design needs calculations repeatedly. In fact, alteration of exterior sizes affects speed, force received, equipments layout, then affects position of centre-of-stabilization, centre-of-gravity and centre-of-buoyancy. At last, the math model needs rebuilding. Due to limits of inner room and carrying capacity, design of structure needs dressing by screening carefully. With simulation, this paper gets reasonable parameter.
