Study On Simulation Experiment Of Fuze Warhead Coordination For Trajectory-attitude Compound Encounter

Trajectory-attitude compound encounter is the composite encounter of the relative trajectory and attitude between ammunition and the target.Under the background of the development of intelligent ammunition,it is an important trend for intelligent ammunition to equip with the focus warhead with high energy efficiency and minimized collateral damage.Accordingly,fuze-warhead coordination arises new problems which existed in the composite encounter of the relative trajectory and attitude between ammunition and the target,rather than only relative trajectory.In this paper,at the research background of a typical representative of trajectory-attitude compound encounter——loitering ammunition equipped with multi-mode EFP warhead,a simulation experiment is made to simulate the special fuzewarhead coordination of trajectory-attitude compound encounter.The main research of this paper are as follows:? At the basic of the process of loitering ammunition working and composited the laboratory simulation system,the similarity relation between laboratory simulation system and the real loitering ammunition system is dissected.Then,a suitable simulation experiment scheme is established.? A mathematic model of fuze-warhead coordination is built.At the basic of essential assumptions,a mathematic model and attitude control method of fuze-warhead coordination is built.Then,the optimal fuse delay time and adjust angle are figured out.The validity of the algorithm is verified by computer simulation.? A fuze-warhead coordination simulation experiment is made based on Lab VIEW and d SPACE.In the laboratory condition,selecting the acquisition mode of relative motion information and attitude information.An initiation control algorithm is built in Lab VIEW environment,and then,sending the optimal fuse delay time and adjust angle to d SPACE simulation processor to control the rock platform swing and simulate initiation process.The evaluation method of simulation experiment results is established,and the experimental results are analyzed and the experimental results are evaluated.? A Hardware-in-the-loop simulation experiment is made based on DSP and d SPACE.At the basic of Lab VIEW and d SPACE simulation experiment,the DSP processing chip is used in experiment to run the initiation control algorithm?acquire relative motion information and ammunition attitude information.
