Description
The present invention relates to a method for expressing the stability of a ship, and more particularly, to a method of visualizing the stability of a stability using a three-dimensional hull model that can easily evaluate the stability of a tilted ship using a three-dimensional hull model of a ship. .
In general, a loading computer is a program that calculates and evaluates the structural strength stability and fluid stability stability of a ship when the ship is seaworthy after loading.
The loading computer generates the three-dimensional shape of the actual ship from the geometric coordinate information of the given ship, calculates the actual situation that may occur during the ship operation through simulation and outputs the result.
However, since the conventional loading computer is simply represented in a two-dimensional shape when evaluating the stability of the ship according to the inclination angle of the ship, it is not possible to express the attitude of the ship according to the change in the lateral inclination angle and the trim at the same time. there was.
Therefore, there is a need for a method that allows the user to intuitively grasp the stability of the restoring force by using a three-dimensional ship model.
Accordingly, the present invention is to solve the conventional problems as described above, while calculating the stability stability arm value affecting the restoring force according to the inclined inclination angle of the ship, and a three-dimensional vessel model By visually showing various changes in the attitude of the ship according to the hydrostatic calculation results, the stability of restoration using the three-dimensional hull model enables the user to easily prepare a countermeasure according to the ship's inclination. The purpose is to provide a method.
The cross-sectional area calculation method of the ship to achieve the above object, the first step of generating the three-dimensional shape information of the ship, and using the three-dimensional shape information to calculate the hydrostatic restoring force according to the inclination angle of the ship And a third step of displaying stability stability information according to an inclined angle by using the hydrostatic restorative force calculation result.
Here, in the first step, the three-dimensional shape information is preferably displayed by dividing each part in different colors in the three-dimensional shape information in order to change the center of gravity for each part of the ship.
In addition, the second step preferably further comprises setting the sailing conditions and loading conditions of the ship.
As described above, the present invention uses the three-dimensional ship shape model to visualize the stability stability (degree) according to the hydrostatic, so that the user can easily understand the loading computer calculation result while intuitively recognizing the three-dimensional shape There is an advantage. In addition, it is believed that this will contribute to the improvement of user convenience in evaluating the structural strength stability and the fluid restorative stability in the solid application of the loading computer.

4 is a view showing the three-dimensional shape information of the ship in the stability stability visualization method using a three-dimensional hull model according to the present invention.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In describing the present invention, the defined terms are defined in consideration of the function of the present invention, and should not be understood in a limiting sense of the technical elements of the present invention.
As shown in Figures 1 to 4, in the restoration stability visualization method using the three-dimensional hull model according to the present invention, it is possible to calculate the stability stability arm value that affects the restoring force according to the inclination angle of the ship. In addition, a ship model having a three-dimensional shape of a ship has a feature that can intuitively visualize and show a user's posture change according to the hydrostatic calculation result.
To this end, the first step (S100) of the present invention generates the three-dimensional shape information of the vessel to be displayed through the main screen of the loading computer. That is, since the three-dimensional shape information of the ship is represented in the same or similar form to the shape of the actual ship, the user can easily recognize it visually.
And in the first step (S100), in order to change the center of gravity for each part of the ship, it is preferable to display each part by dividing each part in different colors in the three-dimensional shape information.
That is, several cabins can be represented in different colors to be distinguished, and the center of gravity of the ship can be arbitrarily set by giving conditions such as loading information to the separated cabins.
Next, the second step (S200) calculates the hydrostatic restoring force according to the inclination angle of the ship using the generated three-dimensional shape information. Here, the second step (S200) may include the step of setting the sailing conditions and loading conditions of the ship.
Here, the navigation condition and the loading condition can be input and changed through the loading computer, and the restoration stability of the ship is displayed to the user through the main screen of the loading computer according to the input value. That is, as shown in Figure 2 can be easily evaluated the stability according to the various movements and postures of the ship.
Accordingly, the three-dimensional shape information of the ship can be changed to various inclinations as the user inputs an arbitrary value through the screen of the loading computer, and the stability of the ship is changed along with the restoration stability information according to the loading of the loading computer. Is displayed.
Next, the third step (S300) displays the restoration stability information according to the inclination angle of the ship using the hydrostatic restorative force calculation results. Here, the indication of the stability of stability may be variously expressed by numerical values, graphs, pictures, etc. on the main screen of the loading computer.
As a result, the present invention uses the three-dimensional ship shape model to visualize the stability stability (degree) according to the hydrostatic, so that the user can easily understand the loading computer calculation result while intuitively recognizing the three-dimensional shape of the ship . It can also contribute to improving user convenience in evaluating structural strength stability and fluid restorative stability in the solid application of the loading computer.
Although the technical idea of the restoration stability visualization method using the three-dimensional hull model according to the present invention has been described with the accompanying drawings, this is illustrative of the best embodiment of the present invention, but not limited to the present invention.
Accordingly, it is a matter of course that various modifications and variations of the present invention are possible without departing from the scope of the present invention. And are included in the technical scope of the present invention.
