Research On MRSI Of Electromagnetic Guns

Based on the objective environment of modern military development,researchers in various countries are committed to studying how to improve the damage probability of weapon system.As a new concept weapon,electromagnetic gun has the advantages of high initial velocity,high kinetic energy and high damage compared with traditional gun.Compared with the traditional shooting method,the multi shot simultaneous bounce shooting method,which is called "combat effectiveness multiplication method",can effectively improve the effectiveness of hitting the target to a certain extent.Therefore,if the firing mode of multiple simultaneous bullets is applied to the electromagnetic gun weapon system,the purpose of improving the strike effectiveness of electromagnetic gun weapons can be achieved.Based on this research purpose,the main contents of this paper are as follows:The mathematical model of multi shot simultaneous impact of electromagnetic gun is established.Based on the realization method of multi shot simultaneous impact,the basic principle of multi shot simultaneous impact control of electromagnetic gun is clarified,and the constraint conditions for multi shot simultaneous impact of electromagnetic gun are given.Based on the above contents,the mathematical model of multi shot simultaneous impact of electromagnetic gun is established,and the realization of multi shot simultaneous impact of the same static target in different ranges is simulated and analyzed,the feasibility and scientificity of the model are verified.Complete the error analysis and probability error calculation of multiple simultaneous impact of electromagnetic gun.Firstly,according to the error analysis,the influence of each error on the external trajectory of the electromagnetic gun is simulated,and then the hit probability of a single shot of the electromagnetic gun is obtained by simulation.Combined with the allowable error value of multiple shots at the same time,the hit probability of multiple shots at the same time is calculated.However,because this hit probability cannot be calculated directly,an average hit number is introduced to represent the hit probability of multiple simultaneous hits of electromagnetic gun.Calculate the damage probability of multiple simultaneous impact of electromagnetic gun.Analyze the target characteristics,establish the damage probability calculation model of multi shot simultaneous impact of electromagnetic gun,calculate the damage probability,and compare it with the damage probability of multi shot sequence impact of electromagnetic gun.Finally,simulate and analyze the relationship between the damage probability of multi shot simultaneous impact of electromagnetic gun and the allowable error.The conclusion of theoretical analysis and simulation test shows the necessity of the research content;The feasibility of multi shot simultaneous impact of electromagnetic gun at different ranges is verified by simulation,and the conclusion that the number of multi shot simultaneous impact projectiles increases with the increase of range is obtained;Through the simulation and analysis of the hitting probability of the electromagnetic gun with multiple simultaneous projectiles,it can be concluded that the hitting probability decreases with the increase of the range;Through the comparative calculation of the two kinds of damage probabilities of electromagnetic gun multi shot sequence impact and electromagnetic gun multi shot simultaneous impact,it can be seen that under the same range,the damage probability of multi shot simultaneous impact is higher than that of multi shot sequence impact;The simulation shows that the relationship between the damage probability and the allowable error of electromagnetic gun multi shot simultaneous impact basically satisfies the convex function;In view of the limitations of the research process,the future research directions are given.
