船体

The research aims at a data of the ship body that acquired according to the triangle diagraph method of laser.

通过NURBS方法进行船体分段面重建，调用OpenGL进行船体分段面模型的三维显示。

I have used it on a fiberglass hull and a kevlar hull without any problems.

我曾用它在一个玻璃钢船体及芳纶船体没有任何问题。

The following is the main works of the paper.1 The weight and the center of weight of the whole hull, analysis by statics the weight of steel, the equipment, oil, water, crew and cargoes etc., conclude a method of calculating the weight and the center of weight of the whole hull,2 Work out the series of formula of distributing the water pressure of wave to the corresponding nodes on the plate, conclude a method of calculating the flotage and the center of the flotage,3 Analysis the method of adjusting the equilibrium of the hull, the finite element module of the hull, and the character of the linetype, by ship statics principle, work out a series of formula of adjusting longitudinal slant, preliminarily confirm the parameter and the range,4 Program in FORTRAN, and link into ANSYS, for auto-loading when analyzing the whole hull by the FEA,5 Make the finite element module of a real hull, calculate the weight and the center of the weight, the flotage and the center of the flotage, compare the result of manual calculation with the computed result, analysis the deviation of the program.

3通过分析船舶常用浮态调整方法、船体结构有限元模型和船体线型特征，运用船舶静力学原理，推导船舶浮态纵倾调整公式，分析了基于船舶结构有限元模型的纵倾浮态调整方法和初步探讨了纵倾浮态调整中的参数确定方法以及初步确定这些参数的取值范围。 4用本文推导的计算方法和公式开发FORTRAN程序，并编译连接到有限元软件ANSYS中，用于进行整船结构有限元分析时自动加载计算。

As the development of hydromechanics and the computer science,the optimized design method of ship lines based on the theory of hydromechanics has gradually become practical.

随着船舶流体力学理论的不断进步，计算机技术的飞跃发展，基于流体力学理论的船体线型最优化设计已经被欧美、日本、韩国等造船技术先进的国家用于实际的船型设计中，而我国目前的船舶设计部门仍主要采用传统的经验设计法来进行船体线型设计。

Using the auto-loading technology and inertia balance treatment,the nodal loads of the finite element model is set up.

并通过节点力的自动加载技术和惯性平衡处理技术建立有限元模型的节点载荷，在中拱和中垂弯矩作用下，计算出船体在压载和满载工况下的船体应力和变形。

However, ship designoptimization in present time mainly focuses on a few aspects, such as ship sectiondesign considering ship hull longitudinal strength, and ship section design oncontainer ships with large hatch, while structure optimization designs of jib armstructure of giant floating crane are comparatively few.

但纵观目前船舶结构优化设计，大多集中在几个方面，如考虑船体总纵强度特性的船体横剖面优化设计、具有大开口截面特点的集装箱类横剖面优化设计等。

It is ideal for the keelson and the in-fill pieces of fully planked hulls and is commonly used as base planking on double planked hulls because it is tough and does not splinter easily.

它是理想的龙骨和木板船体的填补块，还是双层船壳板船体的常用基础板材，因为它结实不容易裂。

Improving upon hull below and rigging above, he makes a proud merchantman, to be wafted by the winds from continent to continent.

通过改进船体水下部分，并在船体上安装上风帆，他就成了令人骄傲的商人，让风将他从一个大陆送往另一个大陆。

The two phenomena have the common characteristic that they are a monotonic function of time inducing a systematic decrease of strength.

船体强度的退化是腐蚀和疲劳共同作用的结果，这两种现象具有一个共同的特征，即它们都能导致船体梁强度随时间单调退化。

After the contract signing in Beijing, design work commenced in Shanghai just 22 months before the launch. The keel laying took place in February 2006 when the frst of 282 massive steel blocks was placed in the dry dock.

在出坞前仅22个月，该船体建造合同在北京签署，随后设计工作便紧锣密鼓地在上海展开。2006年2月，282块船体钢铁组块中的首个组块在干船坞内铺设，船体组块铺设工程正式开始。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
