将有关优化技术、可靠性理论和模糊数学有机地结合起来，提出了基于可靠性的鱼雷圆柱形壳体模糊优化设计方法。这种方法不但充分考虑了可靠性指标的要求，而且考虑有关设计参量和约束条件所具有的随机性和模糊性，从而使壳体设计结果更加符合实际。算例表明，本文方法比传统的鱼雷壳体设计方法能进一步减轻结构质量，这对提高鱼雷系统性能具有重要意义。
Combining optimization techniques, reliability theory and fuzzy mathematics, the fuzzy optimal design method of torpedo cylindrical shell based on reliability is proposed. This method not only fully considers the requirements of the reliability index, but also considers the randomness and fuzziness of the design parameters and constraints so as to make the shell design result more realistic. The example shows that the method proposed in this paper can reduce the quality of the structure further than the traditional torpedo shell design method, which is of great significance to improve the performance of the torpedo system.
