[Abstract]:With the progress of science and technology, electrical equipment under water, the rapid development of water transport resources, underwater equipment is used more and more widely, which makes use of underwater connector has increased dramatically. The reliability of underwater connector for underwater power grid, underwater communication equipment, and water under water resources under the influence of transportation very large. Therefore the development of test equipment for underwater connector is imperative. This paper research status of connector test research existing underwater, according to the project requirements and the need to test conditions of underwater connector were analyzed in the process of rapid pull pressure environment, determine the overall design of the testing device the hydraulic system of the test device, hydraulic system, control system is designed, and the hydraulic part carried out the corresponding experiments. The first chapter introduces the connector test with water The research status, in the underwater environment quickly pull off connector on the hydraulic transient tension test, put forward the main research contents of this paper. The second chapter analyzes the universality of pull connector in underwater pressure environment, the connector for a certain project underwater detailed simulation analysis, and introduces the simulation process, obtained the tension process of the underwater pull off connector, pull speed and pressure on the influence of maximum force. The third chapter puts forward the development difficulty of the test device, determined according to the force balance relationship for tension scheme, lists the force balance between the hydraulic cylinder and the connector underwater. The need to measure the physical quantity and measurement scheme, overall scheme and the working process of connector test under water were determined. The fourth chapter makes a detailed design of the hydraulic system of the hydraulic. The system conditions are analyzed, to determine the hydraulic principle, establish the simulation model of the hydraulic system of the hydraulic cylinder, maximum recovery speed and speed adjustable simulation, completed the calculation and selection of energy storage device, the hydraulic cylinder is designed in detail, the test of the dynamic friction of the hydraulic cylinder. The fifth chapter analysis of influence of hydraulic system, hydraulic cylinder piston rod action of pressure vessel pressure, the closed pressure vessel of a project of pressure compensation scheme, comparing with no pressure compensation, closed variation of water pressure in the pressure container, the 3D model of the test apparatus. The sixth chapter puts forward the overall the design of the control system, the software design, according to the test device of work flow measurement and control part of the program, set up monitoring platform, buffer loop and speed part of the test.
