摘要本文主要讲述了通过导师所给的参考船型的CAD横剖面图·基本结构图·总布置图和型线图，模拟所需船型的船舶初稳高和结构的强度。对于货船而言，若是装载情况发生了波动或者是航区在A与B级之间发生变换，也将随之会影响到初高和结构的强度。77114

进行模型的设立时，参照所给船型的CAD图样中各站下的参数，定位正确后的标记点与控制点之间不断的相互靠近来构造出与所给CAD型线图中最逼近的外观。在Hydromax中将系统随之生成的模型msd文件打开，就可以通过功能模块的变化来得出所需数据：基线与重心之间的垂直距离，开始进水的角度，站与站之间的水平距离，回复力臂，横稳性高和稳性衡准数。此外已经得出的各项剖面模数，围绕中和轴产生的惯性矩和基线与中和轴之间的垂直距离也应该与各自想对应的数值对比来使所设船型与所需船型更贴近契合。

Abstract This paper mainly describes the basic structure of the CAD cross section of the ship's reference ship, which is the basic structure of the ship, and the strength of the initial stability and structure of the ship。 For the cargo ship, if the loading of the situation occurred in the area between the A or B and the conversion of the transformation, will also affect the initial high and the structure of the strength。 

Model was established, according to the parameters of ship CAD drawings, correct positioning of the marker points and control points between the continuous close to each other to construct a CAD diagram in the approximation of appearance with the given。 In Hydromax system will be subsequently generated model MSD file open, can be through changes to the module function to derive the required data: angle of the vertical distance between the baseline and the center of gravity and begins to fill with water, standing and stand between the horizontal distance, the righting arm, transverse stability of high and steady equilibrium of quasi number。 In addition have reached the section modulus around the vertical distance from the neutral axis of moment of inertia and the baseline and the neutral axis between should be and each want to corresponding numerical comparative to the ship and the ship closer to fit。
