Virtual Simulation Technology Research Of Rotating Missile Flight Attitude

Aiming at the nonrepeatability of the missile launching test,and the long cycle,large cost,high technical requirements,the paper researched the virtual simulation technology of rotating missile flight attitude.The research was based on the measurement system which is consist of the magnetic resistance sensor,gyroscope and accelerometer and mainly discussed the calculating method of missile attitude angle by using the virtual simulation and OpenGL technology.Meanwhile,the virtual simulation platform of the missile flight with the function of display,playback,access to the location was designed on the software development platform.The main research contents of this paper are as follows:1.Determined the ultimate goal and the overall designing scheme according to the actual testing demand.Detailedly introduced the related technologies of virtual platform on hardware and software.2.Researched the principle of the magnetic resistance sensor,gyroscope and accelerometer in combination with the flight characteristics of missile body.Accomplished the calculation of original data by using the kalman filter and establishing the model of roll angle.3.Simulated 3d model of missile body and launching scenes,analyzed the realization method of simulation platform according to the real environment.Realized the recurrence of missile flight by importing the calculated angle data into the platform.4.Reseached the reliability and feasibility of the simulation platform through the data test.Preliminarily completed demonstration of the missile flight process and the instruction of its functions.The platform provides an intuitive,simple way for analysis and simulation which helps researchers accurately observe and analyze the various factors in the process of missile flight.It also provides powerful theoretical basis for improving the designing scheme of the missile and lays the basis for visual simulation of the flight scene.
