查询词典 absolutely convex hull

In this paper, we use FEM software ANSYS to simulate. Using FEM to evaluate the strength of pressure hull, the FEM model of outer covering and stiffeners can use shell element to establish, but it may waste much computing time to calculate. Therefore, in this paper, we can evaluate more easier by making use of the idea of effective-width, and considering the stiffener/plating combined moment of inertia.

本文采用有限元素分析软体ANSYS进行求解，在有限元素分析的模拟上，外壳与环肋均可用壳元素建立一实体模型来分析，但是在模型的建立上过於复杂，在解析上也需要更多的时间来计算，因此本文采用有效幅度的观念，考虑环肋与壳板间之组合惯性矩，将环肋部分取梁元素来模拟，如此一来可简化建立模型的困难度，且大大的缩短分析的时间。

As long as obtain S-N curve, the actual load history and the cumulative damage rule of the submarine pressure hall, the estimate of the fatigue life with pressure hull become possible.

只要取得船体构件材料之S-N曲线、船体构件之实际负荷履历以及疲劳累积损坏率这三方面的评估资料，即可对压力壳的疲劳寿命进行合理预估。

The research of pressure hull buckle in this paper is to evaluate the global buckle strength. When we discuss the general instability, not only calculate the eigenvalue but also analyse non-linear buckle. At last, we consider the practical material properties to realize the general instability behavior.

本文在压力壳挫曲强度的研究上，主要是针对整体结构之挫曲破坏，在讨论结构之挫曲行为时，除了求解挫曲特徵值，更进一步考虑非线性挫曲，并探讨材料塑性行为对结构挫曲强度的影响，以了解压力壳材料发生挫曲时之实际行为。

First, we accomplished the mathematical model and suitable finite elements of grid notes of the pressure hull, including the model without aperture and model with apertures and other added equipments.

首先，本文完成了德国U209型潜舰压力壳(含未开孔模型与开孔模型)之数值模型与网格，并以此模型测试使用不同尺寸的内肋骨补强下，外壳所承受的应力与变形、挫曲强度的不同，藉此推测该设计条件下，最佳的结构设计。

In response to the relationship between cavitations and wake gradient, this paper puts forward 3 kinds of calculating model of propeller exciting force , then puts the actual exciting force into pattern formula, and then obtains a new formula to predict propeller-induced hull surface pressure fluctuations by analyzing and calculating some actual ships.

在深入研究国内外螺旋桨激振力计算方法以及综合分析影响螺旋桨激振力的各种要素的基础上，根据空泡数和伴流梯度的关系，本文提出三种螺旋桨脉动压力的计算模型，将反推得到的实际激振力分别代入模型公式，应用数学统计方法对几条实船进行计算分析，得到用于预报螺旋桨表面力的新公式。
