摘要
In order to further enhance the fragment focusing effect of the warhead, this research was done focusing on the design of linear focusing warhead and fragmentation characteristics. Based on linear focusing principle, an arrangement method of fragments was analyzed. A theoretical model for equal-impulse charge generatrix was established by introducing correction parameter of charge length. By numerical modeling, the fragmentation characteristics of linear focusing warhead were obtained, while the effects of charge length and correction parameter on average fragment velocity, velocity amplitude, and standard deviation were revealed. The results show that when charge length is constant, average velocity of fragments increases with the increase of correction parameter, but velocity amplitude and standard deviation of velocity distribution decrease. When correction parameter is constant, average velocity, velocity amplitude and standard deviation of fragments increase with the increase of charge length. The results can provide a new technology approach for the design of fragmentation warhead.
