摘要: 在对引信发射过载随机过程进行详细研究的基础上,根据模糊理论中信息扩散的原理提出了一种模拟任意温度下引信发射过载的算法。为了使计算出的理论过载更接近于实际发射过载,采用了白噪声加噪的方法,最后通过动态测试试验计算出弹体引信部位对发射过载的响应,从而实现了对引信实际发射过载的模拟,并基于这种思想设计了引信过载随机过程计算机模拟程序。为了验证算法及程序的有效性,对某榴弹炮发射时引信所受的过载进行了模拟,结果与实测引信发射过载基本吻合,达到了研究的目的。

Abstract: Stochastic process of overload during the course of fuze launching is discussed in detail, an algorithm, which can simulate fuze launching overload in any temperature based on the principle of information diffusion in fuzzy theory, is also presented. The calculated theoretical overload is disposed by white noise to approach actual launching overload. At last dynamic test is used to calculate the fuze response for launching overload. So the actual fuze launching overload can be simulated in the computer, and the program of stochastic process of overload is designed based on the idea. To test the validity of the algorithm and the program, launching overload of a howitzer fuze is simulated. The result is found basically to be in accord with actual launching overload of fuze, the purpose of the research is achieved.
