Anti-shock Performance Optimization of a Ship Gear Case
The gear case is important equipment in the ship power system and its anti-shock performance is the significant assurance for the naval vitality. The Pauta Criterion method is used to determine the weak link of the gear case. And that the optimum design of anti-shock performance is done in material and structure aspects which focus on the weak link and danger area of the gear case. The results show that the anti-shock margin of safety of the gear case could be increased using the materials with higher yield limit and also the anti-shock capability. At the same time, the anti-shock margin of safety of the gear case could be improved by thickening the slab of the structure, and the degree of the margin of safety improvement is different due to the difference of the slab thickness modification. The various factors should be considered to evaluate the anti-shock performance of the gear case. The research of anti-shock performance optimization of the naval gear case aims to offer references for the optimum design of the navy system and the equipments.
