Simulation Technology Of Mechanical Environment For The Fuze Of High-Value Artillery Shells

The fuze of high value artillery shells is the fuze assembled by guided artillery shells,which fired by the conventional artillery,in this article,these artillery shells generally has large caliber and high cost.The cast of live shooting is very high.So the fuse called the fuze of high-value artillery shells.The test of shooting range for the fuze has an irreplaceable position in the design and finalization of the fuze,and it is necessary to test several times.The test is required to test the fuze with the live artillery shells,but the cost of the live shooting is high,so the cost of the research and development of the high-value artillery shells fuze is quite large.Conventional weapon intelligence is an important direction for the development of conventional ammunition in the future,and guided artillery shells is an important component of conventional artillery shells,and with the increase of such research,especially some performance indicators of the fuze need to repeat test by live shooting,the problem that the test of shooting range cast too large problem is more and more prominent.The problem that the fuze of high value artillery shells research spends too large will become increasingly prominent.So it is necessary that designing a low cost gun-fire testing device for the fuze of High value artillery shells to replace part of the test of shooting range and to reduce the cost of research and development of fuze.Design of the fuze of high value artillery shells gun-fire testing device requires early theoretical demonstration and simulation.Based on the test of the fuze of high value artillery shells test,this paper studies the simulation theory and method of comprehensive mechanics environment,which including recoil and centrifugal force based on the gun-fire testing device to realize the simulation of the mechanical environment when the fuze is fired,to provide design basis and specific parameters and to do the preparatory work for the design of the gun-fire testing device of the high-value artillery shells fuze.In this paper,the simulation model of the gun-fire testing device is established by the inner ballistic equation and MATLAB,combining with the high-value artillery shells fuze emission environment characteristics and requirements of the design indicators,which the gun-fire testing device need meet,and proposed a launch environment simulation program based on 56-type 85 mm cannon.With MATLAB simulation model comprehensive analyzing of the test device parameters,to meet the requirement of the simulation of the launch environment of the high-value artillery shells fuze,provide design basis and specific parameters for the gun-fire testing device.Develop the loading condition calculation software,reduce the workload of the design of test equipment.It is convenient to get reasonable loading conditions under known firing conditions.Finally,two sets of simulation tests were designed,which by comparing the fuze firing environment of the simulation test device and the fuze firing environment of live firing,to prove the range of parameters according to the theoretical analysis and simulation and the loading conditions solution software can be used for the design of the gun-fire testing device of the high-value artillery shells fuze.This paper provides the theoretical basis and design reference for the design of the gun-fire testing device of the high-value artillery shells fuze,and makes the necessary preparation for the design.The gun-fire testing device of the high-value artillery shells fuze not only saves the cost of research and development of fuze,but also can reduce the criticality of the test environment,the dependence of some experiments on the site,and the difficulty of the test.The gun-fire testing device of the high-value artillery shells fuze can significantly reduce test costs,speed up research and development progress,shorten the development cycle.This paper provides a design reference for the experimental environment that can better realize the mechanical environment when the high-value artillery shells fuze is fired.
