The Underwater Vehicle Motion Control And Research Of Visual Simulation Technology

In recent years，with the advancement of science and technology and the rapiddevelopment of computer graphics display technology, the application field of visualsimulation has been rapidly extended. For example, visual simulation has been widely used incommerce, transport ambulance, fire drills, three-dimensional game development, medicine,space industry, and so on. In military, while there has been a large number of applications andresearch on land, air and space weapons systems development, there has been few research onvisual simulation of underwater ordnance, especially in the infant stage at home. A relativelygood visual simulation system of underwater vehicle can intuitively and vividly reproduce thevisual image of scene on torpedo underwater navigation, reflect the change of torpedo motionparameters in various stages,provide a relatively intuitive analysis method for the torpedoperformance evaluation, the overall design, control system design,development and so on.The torpedo as the main weapons and equipment submarine, one of attacking underwatersurface targets and become one of the main weapon damage, with high reliability, big range,and the high rate, high precision and big kill power, and other features, is the water missiles,is also a kind of complex high, refined, sharp weapons technology. Whether today’s still in thefuture combat Marine environment, torpedo will is a powerful killer weapons, so all over theworld of linhai power on the development of all the torpedo weapons.The main content of the topic is to study the visual simulation of the underwater vehiclemotion, where the underwater vehicle refers to the submarine-launched torpedoes, hereinafterreferred to as torpedoes. It is the first movement to establish a mathematical model of thetorpedo space motion, do packet processing and design a PID controller, then, to do itsmathematical simulation by MATLAB. The object of the entity model involved in thesimulation system is established by the professional3D modeling software Multigen Creator,and some key technologies used in the modeling are described in detail. On the MFCdevelopment platform in the VC++6.0, in order to achieve the scene management and drivethe model object, Vega API interface functions are called to control the model involved in thesimulation scene.In weapon system design and reasoning process, out of the political, economic, securityand so on various consideration, little a lot of physical experiment, so get the material Co.,LTD, it is difficult to its operational effectiveness and reliability to make comprehensiveaccurate assessment.We can use2d chart to observe the torpedo attack process, but can only to chart the form of torpedo and the location of the object relations, indeed, not can all-aroundrepresentation of the torpedo and the target of the campaign process and the position of therelationship between them, are far to be direct.The torpedo motion visual simulation systemthe topic establishes is interactive, real-time and realistic. By the operation of theman-machine interface, users can control the torpedo movement in real-time; display interfacecan realistically and instantaneously display torpedoes attitude and movement process,andthe users can instantaneously observe simulation process and make users think that they arejust in the torpedoes movement environment.The results show that the visual simulation system for torpedo weapons research anddesign has a certain practical value.
