Whole Rerformance Research For Collectivity Escaping Chamber

With the modern navy development, the submarine exploited more and more fast. People pay more attention to the high frequency of submarine wrecking. Nowadays, the wreck of submarine usually happened at the inferior deep sea area, the tradition rescuing methods are no longer fit the requirements for the low efficiency and long waiting time. The collectivity escaping chamber is one of the new methods saving oneself. It is able to carry out escaping without any help. In this paper, we mainly concern the whole performance of the collectivity escaping chamber. Aimed at the complex work state, we considered the metacentric stability and the dynamical stability in the situation of above and below the sea lever, studied the movement from the underwater to the surface, so as to prove that the collectivity escaping chamber will not jump out of the water.We first studied the performances of static force. On the situation of comprehensively considering all function requirements, we consulted the escapingchamber abroad, adopted a software for 3D modeling__Pro/E, set a model, used theanalyzing module of the software, calculated the relative geometry elements, and got the exactly position for the gravity center , buoyancy center. Then we analyzed the differences between the ordinary ships and the collectivity escaping chambers about the stability calculation. We got the data of stability in all kinds of situation for the collectivity escaping chamber by the means of compiling the program. To the dynamical stability above the water, we calculated the high inclination stability to insure the collectivity escaping chamber not to keel over.For the aim of rescuing, we need the collectivity escaping chamber to meet a certain pose to float up, so as to not to issue forth when arrived at the water surface, or keel over on the surface. We used the example of underwater platform, set the mathematic model for movement of the collectivity escaping chamber. We used the mathematic software of Matlab to solve the model, got the movement variety for collectivity escaping chamber in the vertical and horizontal. The result was expressed in diagrams, and it showed that the model is correct.As there is many nondeterministic factors in setting the model, the model calculated above is based on the hypothesize. Here we need to find out the key factors affect the whole performance of the collectivity escaping chamber, and determine the best model of it in the submarine. We set a serials of different models, compared the performances in static force and the movement for each model, find out the most important factors which affected the whole performances for the collectivity escaping chamber, that is the volume of the withstand floating body and the shell in the move plane. Finally decided the best models for collectivity escaping chamber.
