摘要
指出随着下潜深度的增加 ,给现行的潜艇设计计算规则提出了挑战。《舰船通用规范》将腐蚀补贴厚度和超深附加深度与下潜深度线性相关 ,使深水、大直径潜艇背上补贴厚度过重的包袱和深度达 2 0 0～ 30 0m的超深附加深度。建议把腐蚀补贴厚度不放在安全系数中 ,而按照不同材料、不同服役年限、不同使用部位外加腐蚀补贴厚度的方法来解决 ;建议用在不同深度时限制潜艇的使用航速 ,超过工作深度后 ,限制潜艇的下潜纵倾角 ,及确定一个比较合适的挽回时间的思路来确定超深附加深度。
This paper put that increase of submergence depth challenges calculation rule of submarine deˉsign.Because《General specifications for naval ships》linearize realationship between corrosion subsidy thickness and additional depth except limiting submergence depth and submergence depth,submarine having high submerˉgence depth and large diameter will bear too heavy corrosion subsidy thickness and additional depth except limitˉing submergence depth to200～300m.Suggest that add corrosion subsidy thickness to different position according to differentput material and military service years but not put corrosion subsidy thickness in coefficient of safety and that determine additional depth except limiting submergence depth according to thinking that limit submarine’s velocity in different depth and submarine’s submergence pitch after exceeding work depth and determine a apˉpropriate retriving time.
