壳板厚度 meaning in Chinese

shell thickness

In the end of this thesis , basis on the structure dimension of a specifically submarine , some solutions for strengthening structure are discussed , such as increasing the thickness of shell , reducing the spacing of frames , increasing the bending inertial moments of frame and setting the intermediate stiffer , when the extreme diving depth becomes 450m or 600m . comparing these structure weights , the excellent solution is the lightest structure
本文最后以某核潜艇指挥舱的结构形式作为计算实例，对下潜深度分别增加到450米和600米的情况，选择增加壳板厚度、缩小肋骨间距、增加肋骨尺寸以及加设中间支骨等加强方案，经分析确定其中结构重量最轻的方案为最佳设计方案。
