Abstract

Abstract: The timely detonation of warhead with proximity fuze is related to whether it can effectively attack and destroy a target. The optimal coordination relationship of fuze and warhead is proposed. A mathematical model of warhead power is established. The relationship between related parameters is analyzed using the particle swarm optimization algorithm, and the inertia weight is dynamically updated using the Euler distance method. An improved particle swarm optimization algorithm was presented and applied to the mathematical model to obtain the calculation model of warhead power in fuze-warhead coordination. Through simulation experiments, the relationship among lethal area, burst height and falling angle was obtained, the best power conditions for fuze-warfare coordination were determined, and the maximum lethal area, the corresponding interval of 90% lethal area and the corresponding burst height were calculated. The results show that the proposed method has higher calculation accuracy of the maximum lethal area than the traditional method, and has faster convergence speed than the particle swarm optimization algorithm, which can better meet the speed calculation requirements for the range test and tactical fied firing.
