Background

Based on the requirement of high safety of the nuclear power plant structure, a series of simulation calculation analysis needs to be carried out on the nuclear power plant structure in the design process according to different working conditions, such as self weight, soil pressure, shrinkage creep, earthquake and the like, and finally, the structural reinforcement of the nuclear power plant and a specific design scheme are determined. In the simulation calculation process, the modeling work is the most complex work, and the workload accounts for the largest part.

Compared with a civil structure, in order to meet the arrangement function requirements of a nuclear power plant system, inclined walls, annular walls and irregular walls are relatively more, so that the plane arrangement is more complex, the modeling of the bottom plane outline in the modeling process is most complicated, a civil common shaft network modeling method is not suitable for the nuclear power plant structure modeling process, a general finite element program is adopted for single-component sequential modeling in the current nuclear power plant structure modeling, the modeling mode is time-consuming and slightly careless, and a three-dimensional model is not consistent with an actual engineering design drawing after the two-dimensional plane arrangement is wrong.

In the structural design stage of a nuclear power plant, a planar template graph is updated in real time and can accurately describe the real situation of the structural design process of the nuclear power plant, but the nuclear power structural planar template graph contains more information, such as a modeling reference line, a wall contour line, a hole, an embedded part, a dimension marking line and the like, and model information in structural simulation calculation only relates to the contour line and the hole, so that the current simulation calculation and design processes are mutually independent processes, and the planar template graph does not play a role in the three-dimensional geometric modeling process of the nuclear power plant structure.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 1, the embodiment provides a three-dimensional modeling method for a nuclear power plant based on a two-dimensional planar template diagram, which includes the following steps:

step (1), respectively forming the construction template drawings of each layer into the outline of the wall body of each layer; in step (1), it is first determined that the entire nuclear power plant is divided into several layers, for example, in the present embodiment, the entire nuclear power plant is divided into three layers, and then each layer needs to be formed into the outline of the wall of the layer. Specifically, the construction template drawings of each layer are classified according to a modeling reference line, a wall body outline, a hole, an embedded part and a dimension marking line; the layer classification can be performed in common two-dimensional plane design software, such as CAD software. After the classification of each layer is completed, the layer information of the openings, the embedded parts and the dimension marking lines of each layer can be deleted, and the outline of the wall body of each layer is reserved, as shown in fig. 2.

Step (2), simplifying the outline of the wall body of each layer; the method comprises the steps of firstly obtaining the outline of the wall body of each layer, and then simplifying the outline of the wall body to achieve the purpose of subsequent rapid modeling. A simplified approach is then to take the median line of the wall profiles of the various levels. It is worth noting that in the simulation calculation process of the nuclear power structure, only a wall body with the thickness of more than 100mm needs to be considered for simulation, and therefore a partition wall with the thickness of less than 100mm does not need to be provided with a central line. Because the wall bodies are different in shape, when the center line is taken for the outline of each layer of the wall body, the center line of the wall body is taken as the center line for the straight wall; the arc wall takes the central arc line of the wall body as a central line; the irregular wall body takes the connecting line of the end points of the adjacent regular wall bodies as the center line, and all the center lines are combined to form the closed contour line of the wall body, as shown in fig. 3. And connecting the obtained central lines to form the closed contour line of the wall body of each layer.

It is worth noting that after the closed contour lines of the wall bodies of all layers are formed, the contour lines need to be checked and repaired; specifically, whether coincident nodes exist at the same position is checked, if so, the repeated nodes are repaired and combined into a unique node; checking whether a superposed line exists at the same position, and if so, repairing and combining the repeated lines into a unique line; and checking whether a gap exists between two adjacent contour lines and no common node exists, if so, coinciding the two nodes of the two adjacent contour lines to ensure that the two adjacent contour lines are in common node. Through the inspection, the unique contour line can be ensured, no breakpoint exists at the joint, and the establishment of a subsequent model is facilitated.

Step (3), determining the elevation of the contour line of each layer and offsetting; in step (3) of this embodiment, the elevations of the various layers of the nuclear power plant are determined, and the elevations are noted on the closed contour line of the wall. It should be noted that after the elevation of the centering line is completed, the closed contour lines of the wall bodies of all layers should be converted into primitive information of a two-dimensional plane, and the format of the primitive information is a format which can be opened by three-dimensional modeling software, such as a universal iges format, so that data related to the closed contour lines of the wall bodies are ensured not to change in the three-dimensional modeling process.

Step (4), according to the elevation, upwards stretching is carried out by taking the contour lines of all layers as a reference to generate a wall surface; and according to the elevation, the wall surface is generated by upwards stretching by taking the contour lines of all layers as the reference. Specifically, the stretching height of each layer can be determined by the difference of the elevations of each layer due to the difference of the elevations of each layer; after the stretching height of each layer is determined, the contour lines of each layer can be upwardly offset by a height, so that the top surface and the bottom surface of one layer are formed, and an upper and lower point connecting line is formed between the top surface and the bottom surface; and then the wall surface can be formed by stretching the contour line along the connecting line of the upper point and the lower point. It is noted that in other embodiments, if the modeling software can construct the three-dimensional model and the primitive information for the two-dimensional plane at the same time, the format of the primitive information need not be converted.

Step (5), building a floor exceeding the contour line at the elevation of the contour line of each layer; in step (4) of this embodiment, the contour lines of the respective layers are first placed in a planar coordinate system, so that the coordinate values of the nodes of the contour lines of the respective layers can be obtained in the coordinate system, and the maximum and minimum coordinate values x in two directions of the horizontal X, Y are calculated_min,x_max,y_min,y_maxWherein:

x_min＝min(x₁,x₂,x₃…x_n)

x_max＝max(x₁,x₂,x₃…x_n)

y_min＝min(y₁,y₂,y₃…y_n)

y_max＝max(y₁,y₂,y₃…y_n)。

that is, pass x_min,x_max,y_min,y_maxThe rectangle formed by the four straight lines can completely surround the contour line and is tangent to the edge of the contour line. Then, a floor exceeding the contour line is created at the elevation of the floor of each layer, and the area of the floor is as follows:

x＝[x_min-1,x_max+1]

y＝[y_min-1,y_max+1]。

the floor beyond the contour line can ensure that the contour line is completely covered and no edge line without entity is generated due to tangency.

And (6) cutting and deleting redundant faces of the floor exceeding the contour line through Boolean operation to form a three-dimensional model of the nuclear power plant. When the three-dimensional model of the nuclear power plant is cut through Boolean operation, the floor is cut into a cell by the projection lines of the upper and lower layers of wall bodies, wherein the bottom side line of the floor and the projection line of the wall are the same line, and then the outer edge graph of the floor is deleted to obtain the final three-dimensional model of the nuclear power plant.

The embodiment also discloses a nuclear power plant three-dimensional modeling system based on the two-dimensional plane template diagram, which comprises a data initialization subsystem, a model establishment subsystem and an inspection and repair subsystem; the initialization subsystem comprises a layer classification module, a contour line processing module and a derivation module which are sequentially connected, the derivation module returns data to the layer classification module to form an internal circulation of the initialization subsystem, and the initialization subsystem performs circular scanning until a two-dimensional plane template graph completely completes an initialization process. The model building subsystem is responsible for processing data from the initialization subsystem to complete three-dimensional modeling and comprises an elevation bias module, a stretching module and a forming module. And finally, the formed model is inspected and adjusted to be perfect for three-dimensional modeling by an inspection and repair subsystem, and the inspection and repair subsystem comprises a maintenance module and a calculation module.

Specifically, the layer classification module is used for forming the construction template drawings of each layer into the outline of the wall of each layer and taking the central line of the outline of the wall of each layer; the layer classification module classifies the layers of the construction template drawings of each layer according to a modeling reference line, a wall body outline, a hole, an embedded part and a dimension marking line, and after the layer classification is completed, the layer classification module deletes layer information of the hole, the embedded part and the dimension marking line of each layer and keeps the outline of the wall body of each layer.

The contour line processing module is used for simplifying the contours of the wall bodies of all the layers, particularly for taking a central line for the contours of the wall bodies of all the layers to form closed contour lines of the wall bodies of all the layers; the contour line processing module takes the center line of the contour of each layer of wall body, and the straight wall takes the central axis of the wall body as the center line; the arc wall takes the central arc line of the wall body as a central line; the irregular wall body takes the connecting line of the end points of the adjacent regular wall bodies as the central line, and all the central lines are combined to form the closed contour line of the wall body.

The maintenance module is used for checking whether coincident nodes exist at the same position, and if so, repairing and combining the repeated nodes into a unique node; checking whether the same position has a superposed line, if so, repairing and combining the repeated lines into a unique line; and checking whether a gap exists between two adjacent contour lines and no common node exists, if so, coinciding the two nodes of the two adjacent contour lines to ensure that the two adjacent contour lines are in common node.

The elevation offset module is used for determining and offsetting the elevation of the contour line of each layer, namely the elevation offset module determines the stretching height of each layer according to the difference value of the elevation of each layer; after the elevation offset module determines the stretching height of each layer, the contour lines of each layer are offset upwards by a height, and an upper and a lower point connecting line is formed between the top surface and the bottom surface.

The stretching module is used for upwards stretching according to the elevation by taking the contour lines of all the layers as a reference to generate a wall surface and establishing a floor exceeding the contour lines at the elevation positions of the contour lines of all the layers. And the stretching module controls the contour line to stretch along the upper and lower point connecting lines to form the wall surface.

After the stretching of the wall surface is finished, the computing module places the contour lines of the layers in a plane coordinate system, obtains the coordinate values of the nodes of the contour lines of the layers in the coordinate system, and computes the maximum and minimum coordinate values x in two directions of the horizontal X, Y_min,x_max,y_min,y_maxWherein:

x_min＝min(x₁,x₂,x₃…x_n)

x_max＝max(x₁,x₂,x₃…x_n)

y_min＝min(y₁,y₂,y₃…y_n)

y_max＝max(y₁,y₂,y₃…y_n)；

and then the stretching module creates a floor exceeding the contour line at the elevation of the floor of each layer, the area range of the floor is obtained by calculation of the calculation module, and the area range obtained by calculation of the calculation module is as follows:

x＝[x_min-1,x_max+1]

y＝[y_min-1,y_max+1]。

the forming module is used for cutting and deleting redundant surfaces through Boolean operation to form a three-dimensional model of the nuclear power plant. When the three-dimensional model of the nuclear power plant is cut through Boolean operation, the floor is cut into a cell by the projection lines of the upper and lower layers of wall bodies, wherein the bottom side line of the floor and the projection line of the wall are the same line, and then the outer edge graph of the floor is deleted to obtain the final three-dimensional model of the nuclear power plant.
