In normal conditions, The angle between the windward section 2 and the waterward section 3 of the ship 1 is set to 80-90°, which is set as a standard reference value, so that simulation and comparison operations can be carried out, and the water entry angle of the ship 1 during normal navigation is set as the standard water entry angle .

In the navigation simulation state, the inclination angle of the windward section 2 changes with the inclination angle of the water-facing section 3, so that the angle between the windward section and the water-facing section is 90-135°. Wherein, in the present invention, the windward section 2 is set as an arc surface, and the water section 3 is also set as an arc surface. As a standard quantity, the simulated navigation operation can be carried out, thereby determining the navigation situation of the ship 1 .

As shown in Figure 4, the section length of the windward section 2 is equal to the section length of the waterfront section 3. At this time, the water entry angle is twice larger than that of the ship 1 during normal navigation, and the distance between the windward section 2 and the waterfront section 3 The included angle is set to 100-125°, and the inclination angle of the upstream section 3 is smaller than the inclination angle of the upstream section 3 during the normal navigation of the ship, so as to perform the second simulated navigation change operation.

As shown in Figure 5, the section length of the windward section 2 is smaller than that of the waterfront section 3, at this time, the water entry angle is three times larger than that of the ship 1 during normal navigation, and the distance between the windward section 2 and the waterfront section 3 The included angle is set to 90-105°, and the inclination angle of the upstream section 3 is smaller than the inclination angle of the upstream section 3 during the normal navigation of the ship, so as to perform the third simulated navigation change operation.

A sailing simulation method based on the windward cross section of the ship specifically includes the following steps:

Please refer to Figure 1 of the manual for details:

S101: The operation of determining the navigation simulation angle of a normal ship. First, measure and determine the slope of the windward section 2 and the water-facing section 3 of the normal ship 1, and then measure and mark the water entry angle according to the navigation simulation requirements, and then measure the water entry to determine the normal ship. The water entry position of the upstream section 3 of 1 is marked, and the water entry position of the upstream section 3 at this time is the standard position A;

S102: For the first ship navigation simulation operation, change the angle and length of the windward section 2 and the water-facing section 3 according to the simulation requirements, that is, the section length of the windward section 2 is greater than the section length of the water-facing section 3, and the length of the water-facing section 3 The inclination angle of the section is smaller than the inclination angle of the water-facing section 3 when the ship 1 sails normally, and the sailing of the ship 1 is a normal sailing situation. At time 1, the water entry is twice as large, and the water entry position of the upstream section 3 is marked, which is the water entry position B. It can be clearly seen that the displacement of ship 1 has changed during navigation, but the displacement at this time does not change much. Changes with the change of the sailing speed of the ship 1, which makes the sailing of the ship 1 time-consuming and laborious;

103: The second ship navigation simulation operation, according to the simulation requirements, change the angle and length of the windward section 2 and the water-facing section 3, that is, the section length of the windward section 2 is equal to the section length of the water-facing section 3, and the section length of the water-facing section 3 The inclination angle of the section is smaller than the inclination angle of the upstream section 3 when the ship 1 is sailing normally, and the ship 1 is sailing in an abnormal sailing situation (head-down situation, tail flicking), and the windward volume at this time is greater than that of the ship 1 when the ship is sailing normally. Moreover, the water inflow at this time is twice as large as that of the ship 1 during normal navigation, the ship 1 obviously decelerates, and the navigation efficiency becomes lower. At this time, mark the water entry position of the water-facing section 3, which is the water entry position C. It can be clearly seen that The displacement of the ship 1 has changed greatly during the voyage. At this time, the change of the displacement begins to increase, and the displacement will also change greatly with the change of the sailing speed of the ship 1, which makes the navigation of the ship 1 more time-consuming and laborious;

104: The third ship navigation simulation operation, according to the simulation requirements, change the angle and length of the windward section 2 and the water-facing section 3, that is, the section length of the windward section 2 is smaller than the section length of the water-facing section 3, and the length of the water-facing section 3 The inclination angle of the section is smaller than the inclination angle of the water-facing section 3 when the ship 1 is sailing normally, and the ship 1 is sailing in an abnormal sailing situation (yaw, slowing down), and the windward volume at this time is greater than that of the ship 1 when it is sailing normally. And the water inflow at this time is three times larger than the water inflow 1 when the ship is in normal navigation. The speed of the ship 1 obviously slows down, yaws, the displacement becomes larger, and the navigation efficiency decreases obviously. The water entry position of the upstream section 3 is marked, that is, is the water entry position D, it can be seen that the displacement of the ship 1 has changed more during the voyage, and the displacement at this time becomes larger, and it will not only change with the change of the voyage speed of the ship 1, but also make the water entering the ship 1 It is larger, and then causes various changes in the navigation of the ship 1, and the speed reduction or yaw will appear accordingly, so that the navigation speed of the ship 1 will slow down, making the navigation unstable.

To sum up the above steps, it can be known that any change in the standard volume of the windward section 2 and the waterward section 3 will increase the water entry of the ship 1, and it can also be known through simulation that,

Water entry position B > standard position A, the sailing speed of ship 1 does not change much and has no influence;

Water entry position C > standard position A, the sailing speed of ship 1 changes greatly, and the speed of ship 1 slows down;

Water entry position D > standard position A The sailing speed of ship 1 changes greatly, which affects the sailing speed of ship 1, and there is yaw and speed reduction, which seriously affects the speed of ship 1's sailing process.

To sum up the above steps, it can be known that any change in the standard volume of the windward section 2 and the waterward section 3 will increase the water entry of the ship 1, and it can also be known through simulation that,

Water-entry position B>standard position A, water-entry position C>standard position A, water-entry position D>standard position A, and then force the displacement of ship 1 to increase, and make the navigation efficiency of ship 1 lower. becomes larger, which makes the ship's navigation unstable;

Therefore, under the standard quantity, the windward section 2 and the waterward section 3 of the ship 1 cannot be changed arbitrarily.

The above is only a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person familiar with the technical field can easily conceive of changes or changes within the technical scope disclosed in this application Replacement should be covered within the protection scope of this application.
