Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ship cabin design, and particularly relates to a ship cabin wallboard joint arrangement method based on a 3DEXP platform. BACKGROUND

[0002] With the development of large-scale ship, the number of ship cabins in the ship is increasing, which continuously increases the workload of joint arrangement in the design of ship cabin wallboard system. At present, when the joint arrangement of ship cabin wallboard is carried out, the joints of the ceiling and the surrounding wallboard are manually arranged based on two-dimensional software, and the specific method is as follows: based on the two-dimensional cabin layout, the features such as the surrounding wall inner line and the cabin door are referred to, and the two-dimensional top view of each plate is drawn according to personal experience. Then, the three-dimensional modeling personnel obtain data by manual measurement according to the arrangement result, and establish a three-dimensional model of the joint of the ship cabin wallboard in the three-dimensional software. Since the two-dimensional manual arrangement has low automation rate and high error rate, and the data needs to be converted into a three-dimensional model after the arrangement is completed, the joint arrangement cycle of the ship cabin wallboard is greatly increased, thereby affecting the construction efficiency of the ship. SUMMARY

[0003] In view of the above defects, the purpose of the present application is to provide a ship cabin wallboard joint arrangement method based on a 3DEXP platform, so as to improve the joint arrangement efficiency of the ship cabin wallboard.

[0004] The present application provides a ship cabin wallboard joint arrangement method based on a 3DEXP platform, which is used for joint arrangement of wallboards in a ship cabin model, and the wallboards include a ceiling and surrounding wallboards. The wallboard joint arrangement method comprises the following steps:

[0014] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate the present application, and are not limiting to the present application.

[0015] In the description of the present application, it should be noted that the terms "center", "vertical", "horizontal" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0016] As shown in Figure 1 The present application provides a cabin wall panel caulking method based on a 3DEXP platform (3DEXPERIENCE, i.e. 3D experience platform), which is used for caulking wall panels in a cabin model in the 3DEXP platform. The wall panels involved in the present application include a ceiling located on the cabin top and surrounding wall panels located in four directions (i.e. front, rear, left and right directions). The wall panel caulking method of the present application comprises the following steps:

[0017] S1, judging the cabin type of the cabin to be caulked, and determining the ceiling panel arrangement direction in the cabin and the starting ceiling position in the cabin according to the cabin type;

[0018] Specifically, the cabin type includes a bow cabin (whose width direction is the bow-stern direction), a stern cabin (whose width direction is the bow-stern direction), a port cabin (whose width direction is the left-right direction) and a starboard cabin (whose width direction is the left-right direction). In the bow cabin, the panel arrangement direction of the ceiling is from the bow to the stern, and one long edge line of the starting ceiling is aligned with the edge line of the bow part of the cabin top. In the stern cabin, the panel arrangement direction of the ceiling is from the stern to the bow, and one long edge line of the starting ceiling is aligned with the edge line of the stern part of the cabin top. In the port cabin, the panel arrangement direction of the ceiling is from the left to the right, and one long edge line of the starting ceiling is aligned with the edge line of the left side of the cabin top. In the starboard cabin, the panel arrangement direction of the ceiling is from the right to the left, and one long edge line of the starting ceiling is aligned with the edge line of the right side of the cabin top.

[0019] S2, automatically arranging each ceiling panel along the ceiling panel arrangement direction based on the starting ceiling to determine the panel joint position of each ceiling panel;

[0020] When arranging each ceiling panel, the width size of each ceiling panel needs to be determined first. In order to ensure the aesthetic degree of the ceiling panel arrangement, ceiling panels with consistent width size should be used as much as possible for arrangement. The present application preferentially uses standard ceiling panels for arrangement, and the width of the standard ceiling panel is 550mm.

[0021] If the width of the cabin top is not a multiple of the width of the standard ceiling panel, it will not be possible to complete the arrangement with standard ceiling panels, and non-standard ceiling panels need to be additionally arranged for auxiliary arrangement. In order to ensure the aesthetic degree, the absolute value of the difference between the width of the non-standard ceiling panel and the standard ceiling panel should not be greater than 350mm. Based on this, the number and width size of the required non-standard ceiling panels can be determined.

[0022] Specifically, assuming that the ideal number of standard ceilings that can be arranged in the cabin to be caulked is n, the width of the cabin top of the cabin to be caulked is L, and the remaining width after arranging each standard ceiling is S, then L = 550 x n + S (n is a positive integer); if 200 mm ≤ S ≤ 650 mm, then each ceiling arranged includes n standard ceilings and one non-standard ceiling, wherein the width D of the non-standard ceiling is S; if 100 mm < S < 200 mm, then each ceiling arranged includes n-2 standard ceilings and two non-standard ceilings, wherein the width D of the non-standard ceiling is (550 x 2 + S) / 2; if S < 100 mm, then each ceiling arranged includes n-1 standard ceilings and one non-standard ceiling, wherein the width D of the non-standard ceiling is (550 + S) mm.

[0023] When arranging each ceiling, the arrangement of standard ceilings is preferentially completed, and then the non-standard ceiling is arranged in the remaining width space; when the arrangement of each ceiling is completed, the position of the joint of each ceiling can be determined through the joint between the adjacent two ceilings.

[0024] S3, identifying the feature objects on each surrounding wall in the cabin to be caulked, and determining the starting surrounding wall panel position of each surrounding wall in combination with the joint position of the ceiling;

[0025] Specifically, the feature objects include corner panels and door holes; if there is one feature object (i.e. a corner panel or a door hole) on the surrounding wall, the feature object is taken as the starting point of the arrangement of the surrounding wall panel; if there are two feature objects (i.e. two corner panels or two door holes or one corner panel + one door hole) on the surrounding wall, any one of the feature objects is taken as the starting point of the arrangement of the surrounding wall panel; if there is no feature object on the surrounding wall, and the joint of the ceiling of the cabin top is perpendicular to the surrounding wall, one ceiling joint is taken as the starting point of the arrangement of the surrounding wall panel, and it is required that each surrounding wall panel joint is aligned with one ceiling joint; if there is no feature object on the surrounding wall, and the joint of the ceiling of the cabin top is not perpendicular to the surrounding wall, any one end of the surrounding wall is selected as the starting point of the arrangement of the surrounding wall panel.

[0026] The arrangement of the surrounding wall panel on each surrounding wall is independently carried out and does not interfere with each other.

[0027] S4, taking the starting surrounding wall panel position of each surrounding wall as a reference, automatically arranging the surrounding wall panel on each surrounding wall to determine the joint position of each surrounding wall panel.

[0028] The application relates to a ship cabin wallboard joint arranging method, which comprises the following steps: firstly, based on the cabin type of a cabin to be arranged with joints, and in combination with the size of a standard ceiling, the joint positions of each ceiling are determined to ensure the joint arranging beauty of the ceiling; then, according to the feature objects on the surrounding walls and the joint positions of each ceiling, the joint arranging mode of the surrounding wallboards on each surrounding wall is determined, the joint arranging knowledge rule is internalized in the program, and in the joint arranging process, the design personnel intervention and artificial judgment are not needed, the joint arranging result of the whole wallboard can meet the requirements, and the joint arranging efficiency of the cabin wallboard is improved.

[0029] The above only describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, and these improvements and replacements should also be considered as the protection scope of the present application.
