Title Of Dissertation: The Simulation Of Anti-tank Missile Flight Based On ACIS

Mechanics of missile flight attitude research involved the missile dynamics, spaceenvironmental conditions, the consideration of the target motion and the complex factorssuch as missile guidance system. Using computer simulation technology can greatly reducethe needed expensive which are spend on live tests, at the same time shorten the developmentcycle, so in this paper, it is necessary to make a simulation techniques research in the topic ofanti-tank missile flight tentative simulation. If we want to study the projectile posture, wemust establish the3entity model of missile and a target entity model. In this paper, themissile attitude research are firstly from the basic coordinate system, under the basis of therigid body trajectory, analysis various coordinates in missile flight and the conversionrelationship between,, in turn make a force analysis and torque calculation, finally make asimplification process on the basis of rigid ballistics of projectile flight conditions, force andspace with the rigid body trajectory equation and its control equation is obtained. For thesimplification process of the target motion equation and the determination of the guidedmode, then obtain the math model of missile and target in the end.By studying the mathematical model of missile and target, we can use the C++languageand ACIS language written for "roll anti-tank missile flight simulation system" in theplatform of VC++,calculating method of missile flight data by program under certainguidance, making an analysis on Attitude data of pitching moment, roll moment and yawmoment of missile in flight Angle of attack, and doing researches on sideslip Angle,yawAngle, pitching Angle, roll Angle, and getting the curves obtained for different parameters, ithas been a guiding significance to the study of the missile flight parameters.
