Description

Technical Field

[0001] The present invention relates to the technical field of digital ship design, and in particular to a main and auxiliary cable channel design method based on a three-dimensional adaptive tight hook engineering template. Background Art

[0002] In the design of the main and auxiliary cable channels of a ship, if there is no mother ship reference, the existing technology needs to release the risks of adjusting the main scale and spatial layout through three-dimensional design. There is no clear input source for the three-dimensional layout task of designing the main and auxiliary channels in the technical design stage. Based on the uncertain input state, it is difficult to ensure that the main and auxiliary channels are laid out according to the construction and installation requirements, and it is necessary to cope with the iterative update of the channels. When there is a mother ship reference, the existing technology is to create a positioning reference sketch based on the construction drawings to carry out channel layout to meet the radial and horizontal installation requirements of the cable channel. However, there is a problem of interference between the traditional cable hook welds and the hull structure. When the position changes, the sketch needs to be modified, and the steps are cumbersome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide a main and auxiliary cable channel design method based on a three-dimensional adaptive tight-hook engineering template, use the engineering template instantiation method to create an adaptive tight-hook engineering template, and apply the template instantiation to the main and auxiliary cable channel layout, so as to solve the shortcomings of the existing technology, improve the work efficiency of three-dimensional designers in cable channel layout and the three-dimensional refined modeling quality of the main and auxiliary cable channels.

[0004] To solve the above technical problems, the present invention adopts a technical solution: a main and auxiliary trunk cable channel design method based on a three-dimensional adaptive tight hook engineering template, characterized in that:

[0005] A. Create an adaptive cable tie engineering template, using the cable tie installation location coordinates, installation surface, and cable tie model as basic inputs for the cable tie engineering template. Input cable tie location parameters and cable tie model parameters based on actual layout requirements. Arrange the cable tie in the cable channel based on the basic inputs, location parameters, and model parameters.

[0006] B. Establish a main and auxiliary trunk adaptive cable hook engineering template library based on the installation direction and location of the cable channel, call the adaptive cable hook engineering template in the template library according to the corresponding main and auxiliary trunk hook template category, and arrange the main and auxiliary trunk cable channels throughout the ship;

[0007] C. Input the cable hook location information and cable hook specification information, instantiate the adaptive cable hook engineering template, and arrange the cable hooks for the entire channel;

[0008] D. Use the center point of the arranged tight hook as the control point for cable channel modeling, and set the bending radius of the cable channel to 6 times the thickest cable in the channel to complete the 3D modeling of the cable channel.

[0009] Furthermore, the design method specifically includes the following steps:

[0010] S1, building a cable hook installation environment model, wherein the model surface is a hook installation surface, and creating a hook modeling coordinate system based on the cable hook positioning parameters;

[0011] S2, creating a cable hook parameterized model based on the cable hook model parameters;

[0012] S3, creating an adaptive cable tightening engineering template using an engineering template module based on the cable tightening parameterized model;

[0013] S4, establishing a template library for the main and auxiliary trunk adaptive cable hooking engineering based on the installation direction and location of the cable channel;

[0014] S5, calling the adaptive cable hook engineering template in the template library, and inputting the hook positioning information and the hook specification information to complete the layout of the cable channel and the cable hook;

[0015] S6, based on the hook centerline point, hook cross-sectional area and cable channel bending radius on the hook model after instantiation of the engineering template, complete the three-dimensional modeling of the cable channel.

[0016] Furthermore, the cable hook positioning parameters include the height Z of the hook welding point from the ship's BL reference plane, the distance X from the hook welding point to the bow, and the length H of the hook welding leg.

[0017] Furthermore, the cable hook model parameters are set according to the principles of maximizing the model's external dimensions, structural similarity, and minimum number of parameters; the principle of maximizing the model's external dimensions refers to taking the maximum values ​​of the model's length, width, and height; the principle of structural similarity refers to the shape of the rapidly modeled model being similar to the model source; and the principle of minimum number of parameters refers to keeping the parameters that require user modification to a minimum.

[0018] Furthermore, the main-auxiliary trunk hook template category consists of a main trunk hook template and an auxiliary trunk hook template.

[0019] Furthermore, the main trunk tightening template includes the port main trunk horizontal tightening template, the starboard main trunk horizontal tightening template, the port main trunk radial tightening template, and the starboard main trunk radial tightening template; the auxiliary trunk tightening template includes the port auxiliary trunk horizontal tightening template, the starboard auxiliary trunk horizontal tightening template, the port auxiliary trunk radial tightening template, and the starboard auxiliary trunk radial tightening template.

[0020] Furthermore, if the three-dimensional modeling of the cable channel reports an error, it proves that the tight hook arrangement does not meet the process requirements and the cable tight hook positioning parameters need to be adjusted; if the three-dimensional modeling of the cable channel does not report an error, it proves that the tight hook arrangement meets the process requirements.

[0021] Furthermore, the cable hook positioning information is composed of the cable hook positioning parameters and the cable hook model parameters, and the cable hook specification information is the cable hook model.

[0022] Furthermore, the cable tightening parameterized model uses the tightening welding surface elements as the external input of the adaptive cable tightening engineering template, and uses the internal parameters of the model as the custom parameters of the adaptive cable tightening engineering template; when using the adaptive cable tightening engineering template, the custom parameters are determined according to usage requirements.

[0023] An electronic device comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps described in the above method when executing the program.

[0024] Compared with the prior art, the present invention has the following main advantages:

[0025] 1. The present invention uses the installation surface and three-dimensional positioning coordinates of the cable hook as template input and instantiates its engineering. This ensures that the weld feet of the instantiated hook model always fit the installation surface structure and meet radial or horizontal installation requirements, improving the hook positioning accuracy to the millimeter level.

[0026] 2. The present invention adopts an adaptive cable tightening engineering template to set or modify the custom parameters of the cable tightening model, thereby completing the positioning, specification selection and position change of the cable tightening model, which can greatly improve the layout efficiency of the main and auxiliary cable tightening of the ship.

[0042] like Figure 1 As shown, the design method specifically includes the following steps:

[0045] In this example, the coordinates of the hook welding point are X=1000, Z=2000, and a radial reference line is created based on the welding point. The length is the hook leg length H. A radial hook modeling coordinate system is created based on the endpoints and radial reference lines. Figure 2 shown.
