大型船舶模型是完全依照真船的形状、结构、色彩，甚内饰部件，严格按比例缩小而制作的比例模型。因为一旦某个零件比例不同，船模因为其真实的再现原船主要特征，做工精良，其本身蕴含着的是船舶文化，具有很高的收藏价值。一套用心收藏的船模甚可以完整真实的再现一个船舶公司，一个船舶的历史。

A large-scale ship model is a scaled model made strictly according to the shape, structure, color, and even interior components of the real ship, and is strictly scaled down. Because once a certain part proportion is different, the ship model, due to its authentic reproduction of the main characteristics of the original ship, is exquisitely crafted, and it contains ship culture, which has high collection value. A set of carefully collected ship models can even fully and realistically reproduce the history of a shipping company and a shipping brand.

大家心目中的船模是精良细致的，但不过是无数零件的堆叠和拼装而已，只要有点耐心，谁都能拼起来，这有什么难的；拼好的模型也不能下水，只能摆在家里，有钱人消遣时间的玩物罢了。

The ship model in everyone's mind is exquisite and meticulous, but it is just the stacking and assembly of countless parts. With a little patience, anyone can put it together. What's the difficulty of this; The assembled model cannot be put into the water, it can only be placed at home as a leisure item for wealthy people.

我们且不说安装船模的过程中上胶、补色、修剪以及细小精密零件的拼接有多困难，要是要制作一款船模呢？并且同时还附带某些实际性能呢？

Not to mention how difficult it is to glue, add colors, trim, and assemble small and precise parts during the installation of a ship model. What if we want to make a ship model? And it also comes with some practical performance?

制作専业的船模，需要根据船体的型值表和型线图，按一定比例缩小制造的船体模型，是预报实船航行性能和辅助船舶科研教学的重要工具。

To produce a specialized ship model, it is necessary to reduce the size of the manufactured ship model to a certain proportion based on the ship's shape value table and line diagram. This is an important tool for predicting the actual ship's navigation performance and assisting in ship research and teaching.

作为实船试验的近似替代品，船模的可靠性(即动力相似性)与它们的几何相似性密切相关，因此船模曲面不仅要求光滑，而且要求具有较高的几何加工精度。由于船模曲面属于大型对称自由曲面，目前手工放样的制作方式不但加工效率極其低下，而且也难以保证船模曲面的加工精度。

As an approximate substitute for actual ship testing, the reliability (i.e. dynamic similarity) of ship models is closely related to their geometric similarity. Therefore, the surface of ship models not only requires smoothness, but also requires high geometric processing accuracy. Due to the fact that the ship model surface belongs to a large symmetrical free form surface, the current manual layout method not only has extremely low processing efficiency, but also is difficult to ensure the machining accuracy of the ship model surface.

目前，公司级别的船模制作都已经充分利用现有计算机辅助设计(ComputerAided De—sign，CAD)/计算机辅助制造（Computer Aided Manufacturing,CAM)/计算机数字控制(Comput-Numerical Control，CNC)一体化技术，提高船模曲面的加工效率和精度，制作出更加精良的船模。

At present, the production of ship models at the company level has fully utilized the existing computer-aided design (CAD)/computer-aided manufacturing (CAM)/computer numerical control (CNC) integrated technology to improve the machining efficiency and accuracy of ship model surfaces and produce more refined ship models.

除了可以试验，同时，它也是一种船舶/船坞模型的复制形式。可用于大型展览，它们也是船舶的一种推广形式。

In addition to being able to experiment, it is also a replication form of ship/dock models. Can be used for large-scale exhibitions, they are also a form of promotion for ships.

对于传播和设备制造商来说，如何迅速地将他们的产品推向市场是为了让更多的人了解产品，而参与展示是一种非常有效的方式；可以让更多的人对船舶/船坞模型有一定的了解。大型船舶模型

For communication and device manufacturers, how to quickly push their products to the market is to let more people understand the products, and participating in exhibitions is a very effective way; It can provide more people with a certain understanding of ship/dock models. Large ship models
