Research On Visualization Simulation Of External Ballistics Based On MATLAB

With the rapid development of computer technology,simulation technology relying on computer platform has also been widely applied to various fields.Computer simulation technology as a tool for analysis,designing,running,evaluation the complex systems has been more and more application of the national defense science and technology.At the same time,in order to meet the needs of modern warfare,external ballistics has been of rapid development in recent decades,and simulation technology has become the important means for researching projectile trajectory,improving the precision strike capability of non-guided weapons.Based on the Simulink of MATLAB platform,combined with the simulation technology and external ballistic theory,first of all,the article systematically expounds the basic content about simulation technology of external trajectory,and points the mothed for simulation of external trajectory system and lies a theoretical foundation for it.Next, the text studies on simulation of the classical external ballistic theory,on this basis,building the ballistic motion system simulation model.Using the rigid projectile as the research object,we established the bullet of six degree of freedom motion simulation model.Through the simulation,we obtained the result of projectile trajectory and compared with the theoretical result to verify the reliability of simulation model.We studied of the characteristics of different types of multiple ballistic weapons and established a model of external trajectory system based on high frequency weapon,and analyzed the influence of flow field on the lateral displacement of two projectile launched in the same time.In the MATLAB GUIDE environment,we established a graphical user interface of external trajectory to provide a visual man-machine interactive platform for external ballistic simulation researchers.Finally,we discussed the verification,validation and accreditation of simulation model,and analyzed the main causes of errors in the process of trajectory simulation.We summarized the basic conception of simulation credibility and got the assessment model of external ballistic simulation system.
