Problems solved by technology

[0003] In order to ensure the huge pressure difference inside and outside the cabin in the deep sea environment, traditional underwater vehicles must adopt a closed sealing structure, which requires that the shell material must be made of metal and have a certain thickness, and the thicker metal shell is extremely The self-weight of the underwater vehicle is greatly increased. At the same time, the endurance time and navigation direction control of the underwater vehicle are its important performance indicators. Energy and power issues will be the main factors affecting the performance indicators. In the case of a large self-weight , underwater vehicles often need to be equipped with greater power, and their energy consumption is also large. Therefore, the current underwater vehicles with metal shells have a short endurance time and slow heading control

Abstract

The invention discloses an intelligent monitoring three-dimensional composite underwater vehicle shell body and a preparation method of the intelligent monitoring three-dimensional composite underwater vehicle shell body. The underwater vehicle shell body comprises a plurality of layers of structures from exterior to interior and comprises four parts of a corrosion resistance layer, an impact resistance layer, a rigidity layer and a metal sealing layer, one or more strain sensors is / are adopted in the impact resistance layer and the rigidity layer of a three-dimensional composite structure at the same time and introduced into the three-dimensional composite structure, and the stress state of the structure of the shell body is monitored through sensing of the micro-strain of the shell body in the working process. The three-dimensional prefabricated part structure guarantees the mechanical stability of the whole shell body, meanwhile, due to the arrangement of the impact resistance layer and the rigidity layer, the composite underwater vehicle shell body can adapt to different complex underwater environments.
