This paper mainly takes the multi-point detonation method of the prefabricated fragmentation directional warhead as the research object.Through a variety of experimental methods such as theoretical analysis and numerical simulation,the directional gain region of fragments under different initiation methods is studied,and analyzes the series of problems involved in the cooperation between the multi-directional peripheral laser fuze and the prefabricated fragmentation directional warhead,so as to improve the damage ability of the directional warhead to the target.First,the related models involved in the fuse coordination technology are established,such as the missile and target rendezvous model,the multi-directional peripheral laser fuze detection model,the warhead model and the target equivalent model,which lays a solid foundation for the related research on the fuze-warhead cooperation design;Aiming at the difference of target azimuth detection accuracy,two new types of target azimuth detection methods based on six-azimuth and eight-azimuth laser fuze are proposed.The Monte Carlo method is used to simulate and analyze the influence of laser arrangement,projectile speed and detection radius on the target detection probability,and the optimal detonation model under different detection conditions are calculated.Then the finite element numerical simulation method is used to study the damage power of the warhead under the condition of eccentric detonation,including the influence of different detonation methods on the damage power of the warhead,the corresponding relationship between different detonation methods and the warhead’s directional damage area,and the Researches such as changing the detonation method to improve the damage efficiency of the warhead;The analysis of many factors that affect the design of the fuze-warhead coordination under different projectile and eye encounter conditions.Aiming at the fragmentation law of the prefabricated fragmentation warhead,the optimal fuze-warhead coordination method of the multi-directional laser fuze is obtained.Combined with the equivalent model of target vulnerability,the influence of the fuze delay and miss distance on the target damage effect is simulated and analyzed.simulation results show: Under different missile and target rendezvous conditions,matching the appropriate parameters of the fuze-warhead cooperation can improve the damage ability of the directional warhead to the target.
