Design And Implementation Of A 3D Simulation System Of Antiaircraft Gun

In the modern war, the air attack and counter-airraid are the vital modes of battle. Antiaircraft gun has advantages such as muzzle velocity, strong anti-interference ability, quick response, good flexibility, low cost and so on, therefore it has become one of the important air defense weapons and equipment. In the antiaircraft missile tests, the experimental data need to be processed in a timely manner to ensure that the follow-up test effect, and should be able to analyze the test data and storage them safely.In this study, according to the requirements of the project for antiaircraft gun 3D simulation and statistical analysis of the data and related research, according to ballistic firing data inputted by user,do analysis and make simulation, the user can have trajectory simulation of antiaircraft gun trajectory and graphics of simulation trajectory and trajectory simulation’s elements, such as the largest hight of trajectory, rajectory range, angle and rate of fall, time of flight. At the same time, the security of the system and data is ensured by using the method of log authentication, privilege management and some other methods.This paper expounds the design and implementation of 3D simulation system of antiaircraft gun. The existing artillery exterior ballistic simulation method, choose Runge Kutta method to solve the differential equation group,make the antiaircraft gun ballistic simulation. Analyse artillery trajectory equations, first studied in the artillery standard firing conditions,analysed the projectile. Then considered the curvature of the earth’s surface and the acceleration of gravity changes with height, the rotation of the earth, changes in meteorological conditions of projectile centroid motion equations. Finally, considered the various impact conditions make the gun point trajectory equations of motion. The simulation results showed that, the simulation model can make simulation of the actual trajectory of antiaircraft gun.Analysis of the fire control system of antiaircraft artillery hitting equation group, with conventional target motion model of target track simulation, accelerated by hit solving equations of the anti-aircraft gun shooting elements were calculated, and analysis of the initial value selection and iterative algorithm. According to the simulation results, the error of the target is small.In the system design and implementation process, first of all, using the unified modeling language(UML), from the analysis of the demand, through the use case diagram to make clear about the system function demand, and use the pieces framework to summarize the system non functional requirements; then it carries on the overall design of the system, make sure that the modules needed to achieve specific functions; then sub module introduces the detailed design method; finally in the implementation stage of the system using Java and MATLAB to complete the system development.The system realizes the key functions of the trajectory simulation,such ase the fire control system, the authority management, data maintenance, and achieve the initial target of the system..
