摘要: 在鱼雷尾轴机械密封设计时, 为了确定影响尾轴密封泄漏率的设计参数, 建立了鱼雷尾轴机械密封泄漏模型, 分析了分形维数、静环宽度、弹簧比压等设计参数对泄漏率的影响。同时, 在满足特定工况及“零泄漏”要求时, 运用遗传算法选取了分形维数、静环宽度、弹簧比压参数的最佳值。结果表明, 对于鱼雷特定航行工况, 存在静环宽度、弹簧比压、分形维数最佳组合, 使得鱼雷尾轴密封的泄漏率小于3 mL/h。

Abstract: This paper establishes a mechanical seal leakage model of torpedo tail shaft, and analyzes the effects of fractal dimension, width of static ring, and spring pressure on leakage rate in order to determine design parameters of torpedo tail shaft seal leakage rate. In the condition of meeting the requirement of no leakage, this paper optimizes the parameters by using genetic algorithm in the specific conditions. The results show that the leakage rate is lower than 3mL/h in the specific navigation condition of a torpedo when the width of static ring, spring pressure and fractal dimension are in optimum combination.
