Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure.
The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the embodiments of the disclosure can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring the primary technical ideas of the disclosure.
In the related art, when a three-dimensional model of a mine tailing filling and conveying pipeline is established, a great amount of repetitive work needs to be performed by an analyst. Taking the example of building a mine tailing filling conveying pipeline model of 75 sections of pipelines in solidworks, the modeling process generally needs to include the following steps: 1) And sequentially storing the 76 filling pipeline coordinate points into a txt text in a group of two, for example, txt1 stores the x, y and z three-dimensional coordinate information of a first point and a second point, txt2 stores the x, y and z three-dimensional coordinate information of a second point and a third point, and so on, and forming 75 txt texts. Wherein, any txt text is stored as the start point coordinate and the end point coordinate of a section of pipeline. 2) Insert "curve passing through xyz point", read the 75 txt texts formed in the first step, and complete the drawing of all curves. 3) Establishing a 3D sketch, and drawing the 3D sketch along the curve completed in the step 2) to form a three-dimensional curve. 4) The corners of the curve are rounded, and a total of 74 rounded corners are included. 5) A circle is drawn perpendicular to the line generated by the first and second points. 6) Selecting the "scan" feature commands the creation of a three-dimensional pipeline. As can be seen from the above, according to the related art, a large amount of repetitive work is required in building a three-dimensional model of a mine filling pipe, and an analyst is required to be skilled in mastering the use of three-dimensional modeling software.
Moreover, the model building method of the mine filling pipeline in the related art has poor expansibility, and the built model cannot be transplanted. For example, if a mine filling pipeline needs to be changed from 75 sections of pipelines to 80 sections of pipelines, the established mine filling pipeline model of 75 sections of pipelines cannot be applied to the establishment of the mine filling pipeline model of 80 sections of pipelines; the technician needs to start building a mine fill line model of 80 sections of line completely over.
The embodiment of the present disclosure provides a method for designing a mine tailing filling and conveying pipeline, as shown in fig. 1, the method for designing a mine tailing filling and conveying pipeline includes:
step S110, obtaining a macro file for building a mine tailing filling and conveying pipeline model and a parameter setting interface, wherein the mine tailing filling and conveying pipeline model is provided with at least one variable parameter, and the parameter setting interface is used for setting parameter values of the variable parameters;
step S120, establishing a plurality of alternative mine tailing filling and conveying pipeline models according to the parameter setting interface and the macro file;
step S130, carrying out finite element analysis on each alternative mine tailing filling and conveying pipeline model;
and S140, determining a target mine tailing filling and conveying pipeline model according to the finite element analysis result.
According to the design method of the mine tailing filling and conveying pipeline, the parameters of the alternative mine tailing filling and conveying pipeline model can be determined through the parameter setting interface, the mine tailing filling and conveying pipeline model can be quickly established through macro implementation, the speed and the accuracy of establishing each alternative mine tailing filling and conveying pipeline model are improved, the design time of the mine tailing filling pipeline is further shortened, and the design efficiency of the mine tailing filling and conveying pipeline is improved.
The following describes in detail the steps of the method for designing a mine tailing filling and conveying pipeline according to the embodiment of the present disclosure with reference to the accompanying drawings:
in step S110, the mine tailing filling conveying pipeline model may include a plurality of orderly arranged turning nodes, and the mine tailing filling conveying pipeline sequentially passes through the turning nodes. The variable parameters of the mine tailing filling conveying pipeline model can comprise the number of the steering nodes, the serial numbers of the steering nodes and the coordinates of the steering nodes. For convenience of calculation and modeling, the starting point and the end point of the mine tailing filling pipeline can be respectively regarded as a turning node, wherein the starting point of the mine tailing filling pipeline can be used as a first turning node, and the end point of the mine tailing filling pipeline can be used as a last turning node.
For example, in one embodiment, the turning nodes are sequentially numbered in ascending order from the starting point to the end point of the mine tailing filling conveying pipeline, and the sequence numbers are 1, 2, 3, N-1 and N respectively; wherein N is a positive integer and is the number of turning nodes. The number of the starting point of the mine tailing filling and conveying pipeline is 1, and the number of the end point of the mine tailing filling and conveying pipeline is N. In the mine tailing filling and conveying pipeline model, the steering nodes of adjacent serial numbers are connected by the mine tailing filling and conveying pipeline.
In step S110, the variable parameters of the mine tailing filling pipe model may further include a fillet radius at each turning node. Thus, the fillet radius of each corner of the mine tailing filling pipeline model can be adjusted by changing the variable parameters. In an embodiment, the fillet radius at each turning node is a variable parameter, so that in step S200, the fillet radius at each turning node needs to be set, and although this increases the time consumption for setting the variable parameter, the fillet radii at the turning nodes can be independently set as required, thereby increasing the flexibility of the design of the mine tailing filling conveying pipeline. In another embodiment, the fillet radii at each turning node are the same, so that a uniform variable parameter R can be set; in step S120, the variable parameter R is only required to be set, and the setting of the fillet radius at all the turning nodes can be realized.
In step S110, the variable parameters of the mine tailing filling pipe model may further include an inner diameter D of the mine tailing filling pipe. Of course, the variable parameter D may also be replaced by other variable parameters with equivalent effect, such as the inner radius of the mine tailing filling pipeline.
In step S110, as shown in fig. 2, a macro file and a parameter setting interface for establishing a mine tailing filling and conveying pipeline model may be obtained by the following methods:
step S210, recording macro files for establishing a simple pipeline model in three-dimensional modeling software, wherein the simple pipeline model is a mine tailing filling and conveying pipeline model with 1-8 steering nodes;
step S220, extracting variable parameters of the mine tailing filling conveying pipeline model from the macro file, and building a parameter setting interface for inputting parameter values of the variable parameters in a programming tool;
step S230, modifying codes in the macro file according to the variable parameters;
step S240, generating a dynamic link library file, where the dynamic link library file is used to generate a parameter setting interface.
The three-dimensional modeling software is three-dimensional modeling software having a secondary development tool, and may be software having an API (application programming interface), for example. For example, the three-dimensional modeling software is Solidworks.
The concrete method of steps S210 to S240 will be further explained and explained below, taking the simple pipeline model having 6 turning nodes as an example.
Corresponding to step S210, solidworks software can be started first, and a recording macro is clicked to newly build a part. Then, a mine tailing filling conveying pipeline model with 6 turning nodes (namely 5 sections of pipelines) is built, and a macro file of the whole three-dimensional modeling process is generated. And finally, stopping macro recording, and saving the macro file to obtain the required macro file.
The method for establishing the mine tailing filling pipeline model with the 6 turning nodes comprises the following steps of:
step S310, storing the coordinates of the 6 turning nodes into a txt text in a group of two in sequence; for example, the first txt text txt1 stores the x, y, z three-dimensional coordinates of the first turning node and the second turning node, the second txt text txt2 stores the x, y, z three-dimensional coordinates of the second turning node and the third turning node, and so on, the same as 5 txt texts.
Step S320, inserting "a curve passing through xyz points", reading the 5 txt texts formed in step S310, and completing the drawing of all curves.
And step S330, establishing a 3D sketch, and drawing the 3D sketch along the curve completed in the step S320 to form a three-dimensional curve.
Step S340, drawing rounded corners at corners of the curve, wherein the rounded corners include 4 rounded corners.
In step S350, a circle is drawn perpendicular to the straight line generated by the first turning node and the second turning node.
Step S360, selecting a scanning characteristic command to generate a three-dimensional pipeline.
In step S210, the number of turning nodes of the established simple pipeline model may be as small as possible, so as to reduce time consumption and repeated workload for establishing the simple pipeline model, and improve efficiency of obtaining the macro file.
Corresponding to step S220, the parameter setting interface may be generated by:
step S410, extracting variable parameters of a mine tailing filling pipeline model from a macro file;
and step S420, building a parameter setting interface in the programming tool according to the variable parameters. The programming tool may be adapted as a C # language dependent compiler.
It will be appreciated that programming interface code is also written in the programming tool, so that the macro file can read the parameter values of its variable parameters from the parameter setting interface.
Corresponding to step S230, the code in the macro file may be modified as follows.
In step S510, the command "insert two coordinate points of one curve" is modified so that it can insert coordinate points of a plurality of different turning nodes.
For example, the source code is:
wherein, (0, -217.0978, 0) is the coordinate of a turning node in the simple pipeline model; (0, -217.0978, -65.5) coordinates of another turning node in the simple pipeline model; (0, -217.0978, 0) and (0, -217.0978, 0) are connected by a straight line curve.
The modified code is:
wherein, # P1 represents the number of turning nodes, # P2 represents the x-coordinate of the starting point of the curve, # P3 represents the y-coordinate of the starting point of the curve, # P4 represents the z-coordinate of the starting point of the curve, # P5 represents the x-coordinate of the ending point of the curve, # P6 represents the y-coordinate of the ending point of the curve, # P7 represents the z-coordinate of the ending point of the curve, and all the parameters are transmitted through the parameter setting interface.
In step S520, the command "generate one curve" is modified so that it can generate any number of curves.
For example, the source code is:
skSegment＝((SketchSegment)(swDoc.SketchManager.CreateLine(0,-217.0978,0,0,-217.0978,-65.5)))；
the modified code is:
step S530, modifying the command for creating a sketch drawing circle perpendicular to the straight line generated by the first coordinate point and the second coordinate point, wherein the diameter of the circle (i.e. the inner diameter of the mine tailing filling pipeline) can be modified arbitrarily within a reasonable range of the model through the parameter setting interface.
In step S540, the 3D sketch drawing command is modified.
Step S550, modifying the 3D sketch curve chamfering command, and modifying the command for generating a chamfer in the original code by using a variable parameter, for example, the modified code is:
where, # P8 represents the fillet radius.
The code may then be modified to generate a full chamfer command; the modified code is:
in step S560, the "stretch" feature drawing command is modified.
Corresponding to step S240, after the test is passed, the modified macro file may be saved, and a dynamic link library file may be generated in the programming tool, where the dynamic link library file is used to generate the parameter setting interface.
In an embodiment, an error detection code may be further added to the dynamic link library file, and when the coordinates of the turning node exceed a set range, the error detection code may generate an error prompt box. For example, the coordinates of any turning node may be set to range in any dimension (-500,500). Therefore, errors in three-dimensional modeling can be reduced, and modeling efficiency is improved.
In step S120, a plurality of candidate mine tailing filling and conveying pipeline models may be established according to the parameter setting interface and the macro file. Specifically, the establishment of any one alternative mine tailing filling and conveying pipeline model can be realized in the following modes:
step S610, calling the macro file and the dynamic link library file by using three-dimensional modeling software, and opening a parameter setting interface; it is understood that the macro file called by the three-dimensional modeling software is a modified macro file.
Step S620, determining the parameter value of each variable parameter in the parameter setting interface;
and step S630, generating an alternative mine tailing filling and conveying pipeline model.
In one embodiment, the parameter setting interface is shown in fig. 3, and the parameter setting interface includes a plurality of input boxes, and each input box is associated with each variable parameter in a one-to-one correspondence; parameter values for the variable parameters associated with the input boxes may be entered in the respective input boxes.
For example, as shown in fig. 3, a "working list" input box is used to determine a saved list of the generated alternative mine tailing filling transport pipeline model. The pipeline inner diameter input frame is used for inputting the inner diameter of a mine tailing filling and conveying pipeline; and the fillet radius input box is used for inputting the fillet radius of the alternative mine tailing filling conveying pipeline model at each turning node. The parameter setting interface further comprises an input box used for inputting the number of the turning nodes, the serial numbers of all the turning nodes and the coordinates of all the turning nodes. The analyst may input corresponding parameter values in each input box to implement determining the variable parameters in the modified macro file.
In another embodiment, each variable parameter may be saved in a parameter text; and reading the parameter text through a 'read file' command on a parameter setting interface to obtain the parameter value of each variable parameter.
In step S630, after determining the parameter values of the variable parameters, the three-dimensional modeling software may be caused to execute the macro file by a "generate model" command, so as to generate an alternative mine tailing filling conveying pipeline model, as shown in fig. 4.
Therefore, the design method of the mine tailing filling and conveying pipeline can adopt a model-driven parameterized modeling method, calls the API function to develop a special mine tailing filling and conveying pipeline model by using the high-level programming language C #, inputs the inner diameter of the mine tailing filling and conveying pipeline, the fillet radius of the mine tailing filling and conveying pipeline model at each turning node and each turning node through a customized friendly parameter setting interface to realize the automatic generation of the mine tailing filling and conveying pipeline model, greatly shortens the modeling time, reduces the modeling workload and improves the efficiency and the accuracy. Moreover, an analyst does not need to be skilled in mastering the use method of solidworks, and the model of the alternative mine tailing filling conveying pipeline can be established by setting corresponding parameters on the parameter setting interface.
In another embodiment, in step S110, the model of the mine tailing filling and conveying pipeline comprises a model of an existing part of the mine tailing filling and conveying pipeline and a model of a part to be designed of the mine tailing filling and conveying pipeline, and the coordinates of the end point of the model of the existing part of the mine tailing filling and conveying pipeline are the coordinates of the start point of the model of the part to be designed of the mine tailing filling and conveying pipeline; each parameter of the model of the existing part of the mine tailing filling and conveying pipeline is a fixed value.
Therefore, the existing part of the model of the mine tailing filling pipeline has no variable parameters, so that the parameters related to the model do not need to be repeatedly input every time the model of the alternative mine tailing filling conveying pipeline is established; the method can be extended on the basis of the existing model to generate the mine tailing filling and conveying pipeline model, realizes the transplantation of the existing mine tailing filling pipeline model, and improves the efficiency and the accuracy of establishing the mine tailing filling and conveying pipeline model.
In step S130, finite element analysis is performed on each alternative mine tailing filling and conveying pipeline model. The method of finite element analysis may comprise:

The meshing may include: introducing an alternative mine tailing filling pipeline model to be analyzed into finite element analysis software; defining the dimensions of a line grid, a face grid and a body grid; selecting a grid division mode; defining an inlet face, an outlet face, etc.; and generating a grid.

The finite element analysis model may be generated by: selecting a solver; inputting a grid; detecting a grid; modifying the size of the grid according to the actual situation; selecting a format of a solution and solving an equation; setting material parameters; setting a boundary condition; initializing a flow field and setting initial conditions.
And step S730, carrying out finite element simulation calculation.
In step S140, a target mine tailing filling conveying pipeline model may be determined according to the finite element analysis result. The target mine tailing filling and conveying pipeline model is used for designing a mine tailing filling and conveying pipeline.
The design method of the mine tailing filling and conveying pipeline avoids a large amount of repeated modeling work required before finite element analysis is carried out on the mine tailing filling and conveying pipeline system, greatly shortens the modeling period, has high accuracy, improves the working efficiency of finite element analysis and calculation, and is convenient for selecting the optimal model from a large amount of different alternative mine tailing filling and conveying pipeline models as the target mine tailing filling and conveying pipeline model.
