Unmanned underwater vehicle dynamic performance overland test system and test method thereof

Abstract

The invention discloses an unmanned underwater vehicle dynamic performance overland test system and a test method thereof and belongs to the field of unmanned underwater vehicles. The test system structurally comprises an organic working medium evaporator, a preheater, a self-contained pressure regulator, a gas flotation turbine expansion generator, a simulated sea water condensing module and a working medium pump. A PLC controller can control a working medium pump driver according to detected data of an evaporator outlet pressure sensor and an evaporator outlet temperature sensor. The systemperforms overland simulation on the unmanned underwater vehicle working environment, accordingly, overland simulation operation on an unmanned underwater vehicle is achieved, the test flexibility anddynamic performance test efficiency of the system are improved, and the test cost is lowered. Meanwhile, the PLC controller judges whether the superheat degree at an inlet of the expansion generator is qualified or not according to the detected data of the evaporator outlet pressure sensor and the evaporator outlet temperature sensor, the system is regulated through the working medium pump driver,automatic control is achieved, and the working test stability is guaranteed.

Description

technical field [0001] The invention relates to an on-shore testing system for the dynamic performance of an unmanned underwater vehicle and a testing method thereof, which are applied in the field of unmanned underwater vehicles. Background technique [0002] An unmanned submersible vehicle is an unmanned, remote control or automatic control device that navigates underwater. It mainly refers to an intelligent system that replaces divers or manned small submarines for deep-sea exploration, lifesaving, and mine removal. High-risk underwater operations. Therefore, unmanned underwater vehicles are also called "diving robots" or "underwater robots". Unmanned underwater vehicles can be divided into military and civilian use according to the application field. The internal energy supply system of the unmanned submersible usually adopts the power supply system of the battery, but the energy storage of the battery is limited, which limits the sailing time of the unmanned submersibl...

Problems solved by technology

However, the domestic technology of hydrogen fuel cell system is not perfect, and the cost is high, so the system is usually suitable for super large submarine equipment

In the prior art, solid oxidation fuel cells are also used in the submersible power system, but the conversion efficiency is low, and the reusable effect is poor, which increases the application cost

In addition to the above methods, in order to meet the requirements of continuous endurance, the UUV will also use the Rankine cycle as the energy supply system, but the system has many internal structures, and the working environment of the UUV has its own characteristics, so it needs Multiple tests and experiments have been conducted to ensure that the performance of the energy supply system meets the working requirements of the unmanned underwater vehicle, but the test method is relatively cumbersome, which reduces the test efficiency, and the test environment is limited, which increases the test cost and is not conducive to the efficient testing.
