[0003] Using manual modeling by designers in existing technologies has the following drawbacks: Traditional methods of relying on designers to manually create models suffer from problems such as low efficiency, difficulty in making modifications, and long design cycles. The parameters of gravity-type gabion floating frames, such as gabion diameter, total height, floating pipe diameter, number of columns, and bottom ring diameter, are subject to industry design specifications, and the dimensional adjustment relationships are complex. The relevant parameterization methods do not take into account the limitations of design specifications and the complexity of parameter linkage.

[0004] Therefore, in order to solve the above problems and improve the efficiency and accuracy of gravity-type gabion floating frame design and modeling, this invention proposes a multi-parameter joint-driven parametric modeling method for gravity-type gabion floating frames.

Detailed Implementation

[0018] The following description is intended to provide a detailed account of the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0019] See Figure 1-4 This invention provides a technical solution: a parametric modeling method for gravity-type gabion floating frames driven by multiple parameters, driven by four parameters: the circumference of the inner floating tube, the outer diameter of the main floating tube, the number of I-beams, and the height of the columns, including the following steps: S1. Driver parameter input verification First, input and verify four parameters: inner float tube circumference, main float tube outer diameter, number of I-beams, and column height. (1) Obtain the initial values ​​of the inner buoy circumference, the outer diameter of the main buoy, and the number of I-beams.

[0020] (2) The units for the circumference of the inner floating tube and the outer diameter of the main floating tube are unified to millimeters, and the unit for the number of I-beams is set to something other than "piece".

[0021] (3) Refer to Table 1 to perform single-parameter verification of the four parameters. If the input exceeds or does not reach the range, the designer will be required to re-enter it according to Table 1 and a prompt will be given.

[0022] (4) After completing the single-parameter verification, perform a combination rationality verification, checking according to the rule set R in order: The rule set R is divided into two parts: R1 and R2.

[0023] R1 is a geometric constraint, since d 工 With L 内 L 外 N 工 These key parameters are all related, so d is used. 工 As a constraint standard, the calculation rule is: calculate the inner radius r. 内 =L 内 / (2π), determine the distance S between the inner and outer float tubes (for main float tube outer diameters ranging from 250 to 375 mm, take S = 1.2 m; for main float tube outer diameters ranging from 375 to 500 mm, take S = 2 m), and calculate the outer circumference L_outer = L_inner + 2πS; from d 工 =L 外 / N 工 ≤ Limit (see Table 1).

[0024] R2 is the dimensional ratio: check whether the ratio of the inner float tube circumference to the outer diameter of the main float tube is appropriate, and avoid dimensional imbalance. (See Table 2 for specific range).

[0025] (5) Parameter verification passed, proceed to step S2.

[0026] Table 1. Collection of Parameter Ranges Table 2 Requirements for the Ratio of Inner Float Tube Perimeter to Main Float Tube Outer Diameter S2. Generation and Calculation of Follower Parameters Secondly, based on the driving parameters, seven sets of driven parameters are generated: the circumference of the outer floating tube, the distance between the inner and outer floating tubes, the distance between the I-beams, the outer diameter of the I-beams, the outer diameter of the handrail tube, the outer diameter of the column, and the circumference of the handrail tube.

[0027] The calculation order and relationships are as follows: 1. Derivation of the geometric principal quantity: circumference L of the outer floating tube 外 By L 内 The spacing d between the I-beams is obtained from S. 工 =L 外 / N 工 ; 2. Derived dimension: Outer diameter D of the I-beam 工 =k2*D 浮 Handrail tube outer diameter D 扶 With D 立 The relationship between coefficients k3 and k3 is shown in Table 3; the circumference of the bottom ring L is equal to the circumference of the inner floating tube; the circumference of the handrail tube L... 扶 By D 扶 The outer diameter D of the column is obtained. 立 By D 扶 To obtain.

[0028] The relationship between the driven parameters and the driving parameters, as well as the core derivation formulas, are shown in Table 3.

[0029] After completing the calculation of the driven parameters, proceed to step S3.

[0030] Table 3. Derivation formulas for follower parameters S3. 3D mapping Based on the gravity-type gabion floating frame reference model, parametric modeling is performed by modifying the corresponding dimensions of the reference model according to the driving parameters verified by S1 and the driven parameters calculated by S2. Specifically: (1) Modeling of inner and outer floating tubes: By inputting the perimeter of the inner floating tube and the outer diameter of the main floating tube, the corresponding perimeter of the outer floating tube and the distance between the inner and outer floating tubes are calculated according to S2. The perimeter of the inner floating tube corresponds to the radius of the center circle of the plane where the inner floating tube is located in the reference model; the outer diameter of the main floating tube corresponds to the size of the cross-sectional circle of the inner and outer floating tubes in the reference model; and the distance between the inner and outer floating tubes corresponds to the relative position of the inner and outer floating tubes in the reference model. The reference model is updated to realize the parametric modeling of the inner and outer floating tubes.

[0031] (2) I-beam modeling: By inputting the number of I-beams, the spacing and outer diameter of the I-beams are calculated based on S2. The number of I-beams and the spacing correspond to the spacing settings of the I-beam array in the reference model; the outer diameter of the I-beams corresponds to the size of the I-beam cross-section circle in the reference model. The reference model is updated to realize the parametric modeling of the I-beams.

[0032] (3) Column modeling: The number of columns is consistent with the number of I-beams. By inputting the column height, the column outer diameter is calculated based on the number of columns and S2. The column height corresponds to the column stretching length in the reference model; the number of columns corresponds to the number of column arrays in the reference model; the column outer diameter affects the size of the column cross-section circle in the reference model. The reference model is updated to realize the parametric modeling of the columns.

[0033] (4) Handrail tube modeling: The outer diameter and circumference of the handrail tube are calculated according to S2. The outer diameter of the handrail tube corresponds to the size of the cross-sectional circle of the handrail tube in the reference model; the circumference of the handrail tube corresponds to the radius of the center circle of the plane where the handrail tube is located in the reference model. The quasi-model is updated to realize the parametric modeling of the handrail tube.

[0034] The above method can be implemented on an electronic device. This electronic device includes a memory, a processor, and a computer program (e.g., a standalone application or SolidWorks plugin developed based on the VBA macro program) stored in the memory and executable on the processor. When the processor executes the program, the parametric modeling method described in S1 to S3 is implemented. This electronic device can be a dedicated engineering design workstation or a general-purpose personal computer.

[0035] Furthermore, this invention also relates to a computer-readable storage medium (such as a USB flash drive, hard disk, optical disk, server storage space, etc.) on which a computer program is stored. When the program is executed by a processor of a computing device, the computing device performs the parametric modeling method described in S1 to S3 above. For example, a SolidWorks template file containing VBA code implementing the above method is stored on the medium and distributed.

[0036] Based on the above-described parametric modeling method for gravity-type gabion floating frames, the present invention provides the following specific embodiment.

[0037] The parametric modeling method for gravity-type gabion floating frames is implemented in SolidWorks using VBA programming. The system execution steps are as follows: (1) The designer enters four driving parameters in the driving parameter form interface. After confirming the input, the program will check according to step S1. If the check fails, the system will prompt the designer to modify the parameters. If the check passes, the system will proceed to the next step. (2) After the parameter verification is passed, the program automatically calculates the driven parameters according to the S2 logic and pops up the driven parameter confirmation interface for the designer to view and confirm. After confirmation, the driving parameters and the calculated driven parameters are stored in the database and the model parameters are called one by one to update. (3) The program calls the pre-established gravity-type gabion floating frame reference model in the SolidWorks environment, and based on the input of driving parameters in S1 and the automatic calculation of driven parameters in S2, the program uses L 内 L 外 and L 扶 Determine the radius of the center circle of the plane containing the inner and outer floating tubes and the handrail tube respectively; Use S2 to determine the relative positions of the inner and outer floating tubes; Using D 外 D 工 D 立 and D 扶 Update the cross-sectional circular dimensions of the inner and outer floating pipes, I-beams, columns, and handrail pipes respectively; Using driving parameter N 工 And the calculated d 工 Control the number and spacing of the I-beams and columns in the array; Using driving parameter H 立 The program controls the stretching length of the columns in the model. After completing the parametric updates of all dimensions and features, it automatically generates a 3D model of the gravity-type gabion floating frame that meets industry standard constraints and designer input requirements, and outputs the final model file.

[0038] In summary, this parametric modeling method for gravity-type gabion floating structures automatically generates three-dimensional design schemes for gabion floating structures through the combined effect of parameters and constraints. This greatly improves the design speed of gabion floating structures, facilitates the modification and adjustment of design schemes, and also enables the serial generation of gabion floating structure design schemes. By inputting verification and parameter calculation, the design efficiency and accuracy of cage floating frame are improved, avoiding efficiency loss caused by repeatedly consulting manuals during the design process and parameter errors caused by human error. The three-dimensional model is automatically generated by using the benchmark model and driven by the parameter calculation results, avoiding the differences caused by operation steps, personal preferences and other factors in the manual modeling process, thus improving the standardization and consistency of the three-dimensional model of the cage floating frame.
