Abstract

The invention relates to a method for designing a deep sea pressure simulation device through mechanical pressurization. The method comprises the following steps of (S-1) modeling, building a model ofthe deep sea pressure simulation device in simulation software ANSYS, and the model comprises a pressure-resistant device, a supporting part connected with the pressure-resistant device, and a pedestal connected with the pressure-resistant device; (S-2) step-by-step pressurization and topological optimization, on the model established in the step (S-1), applying simulation pressure to the pressure-resistant device through the supporting part, and fixing and constraining the pressure-resistant device through the base; in the optimization process, simulation pressure being applied to the pressure-resistant device, topological optimization being carried out on the pressure-resistant device, then the simulation pressure being increased, topological optimization being carried out again, and the like till the simulation pressure is the design pressure, and topological optimization being carried out to obtain the deep sea pressure simulation device. Compared with the prior art, the method has advantages of quick and convenient design, high accuracy and the like.

Description

technical field [0001] The invention belongs to the field of design simulation for simulating deep-sea pressure, in particular to a method for designing a deep-sea pressure simulating device through mechanical pressurization. Background technique [0002] The ocean accounts for about 71% of the earth's surface area, and contains extremely rich seabed resources, including oil, natural gas, various minerals, etc. Population and economic growth have brought about a continuous increase in demand for resources. Facing land and coastal resources In the situation of gradual depletion, the world will inevitably focus its future development on the deep sea, and the development of the deep sea has become an inevitable trend. [0003] In the key technology field of equipment development, my country's products still cannot meet the demand, and the key supporting systems and equipment are basically monopolized by foreign countries. Therefore, it is particularly important to study and pr...
