7.1.3 Things to watch for:
The method described above will work without any complications for simple tanks
and compartments.However,there are two possible problems,which will occur if
any of them are linked or are defined with boundary surfaces.
7.1.3.1 Linked Tanks:
If you have linked tanks,before copying data in MS Excel,you should un-link them
by simply filling down the parent's Type into the Type of the linked tanks below it:
Select cells,then right-click to bring up the context menu and select Fill Down:
The Compartment definition window should now look like this:
Now you can proceed as before using MS Excel to sort the tanks into the desired
order.After you have pasted the sorted compartment data back into Hydromax,you
will need to re-link the tanks by typing Link or L into the relevant Type rows.
7.1.3.2 Boundary Surfaces
Boundary surfaces pose more of a problem,since their data is not copied from
Hydromax to MS Excel.When you re-paste the sorted data back into Hydromax,
the boundary surface data will be lost and you must re-enter it in Hydromax.This
problem has been resolved in Hydromax 9.6.
8 Inclining experiment
This section describes how Hydromax may be used to simulate an inclining
experiment.This demonstrates the type of simulations that are possible using the
Specified Conditions and Equilibrium analysis methods.
The purpose of an inclining experiment is to determine:
· Lightship mass
· LCG
· GM
8.1 General inclining experiment procedure
Before carrying out an inclining experiment,the following vessel preparation is
required:
· vessel as complete as possible and surveyed to determine weights which will be
added or removed when in service
· boilers and engine sumps are at working levels
· tanks full or empty to avoid free surface effects; boats tight in derricks to avoid
virtual centres of gravity
· all unnecessary items and personnel ashore
· adequate bilge clearance
· inclining weights and spreads are checked and are perpendicular to centreline
8.1.1 Accurately determine vessel displacement and LCG
· density of fluid measured at several locations
· draughts measured at all draught marks
· from the draught marks and the vessel's hydrostatics,the mass and LCG can be
determined
8.1.2 Procedure to determine GM and KG
Weights (which are often made equal) are arranged as shown below:
The weights are then moved in the sequence specified below,and after each
movement,the heel angle is recorded (usually with a long pendulum).
The shift of a weight w by a distance d across the vessel will result in a transverse
movement of the vessel's centre of gravity from G to G'.The shift in the centre ofgravity is given by:
where D is the vessel's displacement.

我可不是英语专业的,我翻译的很不好 若觉得不好可不要骂我啊
7.1.3的内容看下面的
上面描述的工具可以无困难的应用于简单的水箱(船舱)和(防水)隔离舱.无论如何,(他们中的任何一些连接起来或边界曲面被定义)就会有两个可能的问题发生.
7.1.3连接水箱(舱室)
如果你还没有在MS Excel里面拷贝资料就把那些舱室连接起来了,你就用该把把他们断开通过填写母型类型到他下面的连接舱室类型里:
选择元素,然后右击得到菜单然后选择填写:
这个隔离舱的定义窗口现在是这样的:
现在继续操作就像之前用MS Excel 来分类舱室到想得到的序列(命令菜单),在你已经把分类的隔离舱的资料黏贴到Hydromax(稳定强度)之后,你就需要重新连接这些舱室通过分类连接或连接到相关的类别组.
7.1.3.2边界曲面
边界曲面会产生很多问题,因为他们的资料不能从Hydromax 拷贝到 MS Excel.在你重新把分类好的资料黏贴到Hydromax时,这些边界曲面的资料就会丢失,你就必须重新把这些输入到Hydromax里,这个问题已经在 Hydromax 9.6里给予解决.
8 倾斜试验
这部分主要来讲解如何用Hydromax来模仿倾斜试验.这个演示了那些要用到特殊的条件和平衡分析工具的模仿类型 .
倾斜试验的目的是为了确定:
空船质量
纵向中心
(对不起啊,忘记了很熟悉就是想不起来)
