Embodiment 1
[0040] An embodiment of the present invention provides a ship model, including several interconnected ship model parts, wherein, such as Figure 4b As shown, the joints of the ship model parts are chamfered joints. The chamfering has a first chamfering distance d1 and a second chamfering distance d2, and the ratio of the first chamfering distance d1 to the second chamfering distance d2 is 1:1 to 1:3.
[0041] The size of the ship model can be better controlled by setting the joints between the parts of the ship model as chamfered joints, and the error of parts can be reduced.
[0042] Such as figure 2 As shown, the joint of the first ship model part 10 and the second ship model part 20 in the ship model is chamfered joint. Among them, the first chamfering distance d1 and the length, minimum thickness and shear strength of each ship model component meet the preset conditions. Specifically, the first chamfering distance can be calculated using the following formula:

Embodiment 2
[0050] The embodiment of the present invention provides a kind of manufacturing method of ship model, such as image 3 shown, including the following steps:
[0051] Step S10, modeling each ship model component in the ship model according to a preset ratio, wherein the preset ratio is the ratio between the ship model and the real ship.
[0052] The ship model components that form the ship model are modeled by using the proportional relationship between the set ship model and the actual ship. Specifically, each ship model part is drawn according to a preset ratio, and each surface of each ship model part forming the ship model is drawn separately, so that it can be spliced into a complete ship model entity.
[0053] Optionally, the length of each surface of each ship model component can be calculated according to the thickness of the plate to reduce the error.
[0054] Step S20, using the modeling results to cut the production plate to produce various ship model components....

Abstract
The invention relates to the technical field of ship models and provides a ship model and a manufacturing method of the ship model. The ship model comprises multiple mutually connected ship model parts. Chamfers are formed in the splicing places of the ship model parts. Each chamfer comprises a first chamfer distance and a second chamfer distance. The specific value of the first chamfer distance and the second chamfer distance is 1.1-1.3. The first chamfer distance, the length of each ship model part, the smallest thickness and the cutting intensity meet the preset condition. By setting the splicing places between the ship model parts to be chamfer splicing, and setting the specific value of the first chamfer distance and the second chamfer distance in each chamfer, the size of each ship model part can be well controlled and part zeros are reduced. In addition, according to the length of the ship model part, the smallest thickness and the cutting intensity, the first chamfer distancesare set, so raw materials of the ship model parts can be used to the greatest degrees, resource utilization rate is improved and cost for manufacturing the ship model is reduced.
Description
technical field [0001] The invention relates to the technical field of ship models, in particular to a ship model and a manufacturing method of the ship model. Background technique [0002] A ship model is a ship model that is scaled down to a certain proportion according to ship design requirements, and it plays an important role in shipbuilding, ship design, simulation experiments, and teaching. Among them, in teaching and scientific research, the development of ships away from disciplines is mutually promoted and interdependent with the development of hydrodynamic test technology. The results of a large number of ship model tests can be summarized and promoted into theories, and any relevant theory needs to be verified by tests. verify. [0003] In the prior art, making a ship model is to splice each ship model part into a complete part, wherein, such as figure 1 As shown, the first ship model part 10 and the second ship model part 20 are spliced together, and a ship ...
