Research On Simulation Techniques Of Underwater Vehicle Of Submarine Cable Survey

Along with the development of offshore oil and gas in our country is more and more active, especially the deep oil and gas development, the offshore platform under service is increasing year by year. The submarine pipeline is also increasing year by year as an important part of the offshore platform. Thus, as the necessary tool for submarine pipeline detection and maintenance, the underwater robot submarine cable detection system is playing an increasingly important value.This paper firstly overviews the history and development stage of the underwater robot, the appearance of some important products, and the research progress of underwater robot technology around the world, then introduces the research status of underwater robot in our country. This paper completes the equal proportion of "Super Mohawk ROV" model from Sub Atlantic Corporation after deeply understood the structure, fame structure and carrier equipment of the underwater robot, the buoyancy material, the structure and working principle of the propeller, and the working principle of the TSS350system.Then this paper studies the virtual simulation system of the underwater robot submarine cable detection system. This system has the incomparable advantages comparing the traditional training, and is playing an increasingly important role in the training work of ROV pilot. The paper summarizes the content and the basic characteristics of virtual simulation system, the history and development stage of virtual simulation technology, and the application of this system in education, training, engineering design, and industrial manufacturing, etc. This paper has completed the preliminary design of virtual simulation system for ROV submarine cable detection. The basic function achieved by this virtual simulation system is restoring a realistic work environment of ROV submarine cable detection as far as possible in the computer, which can make the ROV pilots have an immersive feeling to complete the real-time interaction with the ROV operators, and finally achieving the purpose of ROV pilot training. Finally, this paper completes the calculation of numerical simulation about the resistance performance of underwater robot. The resistance performance is directly related to the rapidity of the underwater robot. So, it has the vital significance for the underwater robot operating to research the resistance. The resistance of the ROV while underwater sailing is mainly come from the viscous resistance produced by the water viscosity, and pressure resistance caused by the effect of pressure on the surface of the underwater robot. Paper analyzes the size and change rule of viscous resistance and pressure resistance under different speed. And the resistance forecast data of the underwater robot also has certain reference value for engineering application.
