Description

Technical Field

[0001] The present application relates to the field of nuclear power technology, and in particular to a method and device for mechanical analysis of a support member of a nuclear power plant. Background Art

[0002] Nuclear power plants play a very important role in human life and the development of science and technology. Since nuclear power plants are equipped with multiple piping systems and a large number of supports for supporting the piping systems, the mechanical analysis of the supports of nuclear power plants will inevitably affect the structure of the entire nuclear power plant. Therefore, it is particularly important to accurately perform mechanical analysis on the supports of nuclear power plants.

[0003] In the traditional method, all items in the support are directly subjected to mechanical analysis in the global coordinate system of the nuclear power plant. Since the support is too local relative to the nuclear power plant, the global coordinate system cannot accurately express the force conditions of the support, resulting in inaccurate mechanical analysis of the support. Summary of the invention

The server 104 can construct a mechanical analysis model of the target support based on the mechanical analysis model coordinate system, and convert the original pipeline system load into the target pipeline system load under the mechanical analysis model coordinate system, so that the mechanical analysis model performs mechanical analysis processing based on the target pipeline system load. It can be understood that the user can trigger the server 104 to execute the mechanical analysis processing method of the nuclear power plant support through the terminal 102. The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices.

[0064] In one embodiment, Figure 2 As shown, a mechanical analysis method for a nuclear power plant support is provided, and the method is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0065] Step 202 : for a target support in a nuclear power plant, determine the original piping system load of the piping system supported by the target support in the piping system coordinate system.

[0066] Among them, the support parts are used to support the piping system in the nuclear power plant. The original piping system load refers to the load of the piping system in the piping system coordinate system. The target support parts are the support parts to be subjected to mechanical analysis. The piping system coordinate system is a coordinate system constructed based on the direction vector of the original piping system load. It can be understood that the direction vector of the piping system load can be determined in the global coordinate system of the nuclear power plant, and then the piping system coordinate system can be constructed based on the determined direction vector. It should be noted that the piping system coordinate system is equivalent to a local coordinate system constructed with the piping system itself as a reference, which is essentially different from the global coordinate system of the nuclear power plant.

[0067] In one embodiment, the support member includes a pipe clamp. The support member may also include one or more of a steel section, a reinforcing plate, a buried plate, a tie rod, etc. It is understood that the support member uses the pipe clamp to fix and constrain the pipeline.

[0068] In one embodiment, the user can trigger the server to build a geometric model for the piping system and the support in the nuclear power plant through the terminal. It is understood that the server can establish a local coordinate system for each item of the support, so as to use the local coordinate system to build the geometric model of the corresponding item. The server can establish an overall local coordinate system for the support as a whole, so as to use the overall local coordinate system to build the geometric model of the support including multiple items.

[0069] Specifically, the server can determine the original pipeline system load of the pipeline system supported by the target support in the nuclear power plant in the pipeline system coordinate system from the constructed geometric model. It can be understood that the mechanical analysis model refers to an expression of mechanical relationships abstracted from the geometric characteristics of the object under study, so the server can construct a mechanical analysis model of the support based on the constructed geometric model of the support.

[0070] In one embodiment, the server can establish a local coordinate system of the pipe clamp for the pipe clamp of the target support, and use the local coordinate system of the pipe clamp to calculate the load of the pipeline system at the pipe clamp. It can be understood that the support can impose support constraints on the pipeline system through the pipe clamp, and the support constraints have several degrees of freedom, and the original pipeline system load has several direction vectors, that is, the direction and value of the original pipeline system load are related to the support function of the support. The server can determine the direction vector of the original pipeline system load and determine the pipeline system coordinate system according to the direction vector. It can be understood that the server can use the direction vector of the original pipeline system load as the direction vector of the coordinate axis of the pipeline system coordinate system. The original pipeline system load has several direction vectors, and the pipeline system coordinate system has several coordinate axes.

[0071] Step 204, respectively determine the coordinate axes that match each coordinate axis of the global coordinate system of the nuclear power plant from the coordinate axes of the overall local coordinate system of the target support, and construct a mechanical analysis model coordinate system that is close to the direction of the global coordinate system according to the directions of the matching coordinate axes.

[0072] Among them, the overall local coordinate system is a local coordinate system established for the target support as a whole. The global coordinate system is a coordinate system established for the nuclear power plant as a whole. The mechanical analysis model coordinate system is a coordinate system used to construct a mechanical analysis model and perform mechanical analysis on the support.

[0073] Specifically, the server can determine the overall local coordinate system of the target support and the global coordinate system of the nuclear power plant from the geometric model of the target support. The server can determine the coordinate axes that match each coordinate axis of the global coordinate system of the nuclear power plant from the coordinate axes of the overall local coordinate system of the target support, and construct a mechanical analysis model coordinate system that is close to the direction of the global coordinate system according to the directions of the matched coordinate axes.

[0074] Step 206: construct a mechanical analysis model of the target support based on the mechanical analysis model coordinate system.

[0075] Specifically, the server may determine the key point coordinates of the target support member from the geometric model of the support member, and construct the mechanical analysis model of the target support member according to the key point coordinates and the mechanical analysis model coordinate system.

[0076] Step 208: convert the original pipeline system load into the target pipeline system load in the mechanical analysis model coordinate system, so that the mechanical analysis model performs mechanical analysis processing based on the target pipeline system load.

[0077] The target pipeline system load is the load of the pipeline system in the mechanical analysis model coordinate system.

[0078] Specifically, if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, the server can directly assign the original pipeline system load to the coordinate axis under the mechanical analysis model coordinate system based on the parallel relationship between the pipeline system coordinate system and the mechanical analysis model coordinate system to obtain the target pipeline system load, so that the mechanical analysis model performs mechanical analysis processing based on the target pipeline system load.

[0079] In one embodiment, if the pipeline system coordinate system is not parallel to the mechanical analysis model coordinate system, the server can decompose and combine the original pipeline system load according to the directions of the coordinate axes of the mechanical analysis model coordinate system to obtain the target pipeline system load, so that the mechanical analysis model performs mechanical analysis processing based on the target pipeline system load.

[0080] The above-mentioned mechanical analysis and processing method of the support of a nuclear power plant determines the original pipeline system load of the pipeline system supported by the target support in the pipeline system coordinate system for the target support in the nuclear power plant; determines the coordinate axes that match each coordinate axis of the global coordinate system of the nuclear power plant from the coordinate axes of the overall local coordinate system of the target support, and constructs a mechanical analysis model coordinate system close to the direction of the global coordinate system according to the direction of the matched coordinate axes; constructs a mechanical analysis model of the target support based on the mechanical analysis model coordinate system; converts the original pipeline system load into the target pipeline system load under the mechanical analysis model coordinate system, so that the mechanical analysis model performs mechanical analysis processing based on the target pipeline system load. The mechanical analysis model coordinate system is constructed based on the overall local coordinate system of the target support and the global coordinate system of the nuclear power plant, and has the characteristics of both the overall local coordinate system and the global coordinate system. Therefore, the use of the mechanical analysis model coordinate system can more accurately express the force condition of the support and improve the accuracy of the mechanical analysis processing of the support of the nuclear power plant.

[0081] In one embodiment, the original pipeline system load includes the original pipeline load values ​​corresponding to the directions of each coordinate axis of the pipeline system coordinate system; the target pipeline system load includes the target pipeline load values ​​corresponding to the directions of each coordinate axis of the mechanical analysis model coordinate system; converting the original pipeline system load into the target pipeline system load in the mechanical analysis model coordinate system includes: if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, then for the original pipeline load value corresponding to each coordinate axis direction in the pipeline system coordinate system, the original pipeline load value is assigned to the parallel coordinate axis in the mechanical analysis model coordinate system to obtain the target pipeline load value corresponding to the parallel coordinate axis direction; the parallel coordinate axis is the coordinate axis in the mechanical analysis model coordinate system and parallel to the coordinate axis direction.

[0082] The parallel coordinate axes are the coordinate axes in the mechanical analysis model coordinate system and are parallel to the coordinate axis directions in the pipeline system coordinate system.

[0083] Specifically, the server can determine whether the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system. If the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, the server can assign the original pipeline load value corresponding to each coordinate axis direction in the pipeline system coordinate system to the parallel coordinate axis in the mechanical analysis model coordinate system to obtain the target pipeline load value corresponding to the parallel coordinate axis direction. It can be understood that the original pipeline system load includes the original pipeline load values ​​corresponding to each coordinate axis direction of the pipeline system coordinate system and each coordinate axis direction of the pipeline system coordinate system.

[0084] In this embodiment, if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, the original pipeline load value can be assigned to the corresponding coordinate axis in the mechanical analysis model coordinate system directly based on the parallel relationship between the pipeline system coordinate system and the mechanical analysis model coordinate system. There is no need to decompose and combine the original pipeline system load to obtain the target pipeline load value, which greatly reduces the cost of calculating the target pipeline load value.

[0085] In one embodiment, the pipeline system coordinate system includes a horizontal axis, a vertical axis and a vertical axis; if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, then for the original pipeline load value corresponding to each coordinate axis direction in the pipeline system coordinate system, the original pipeline load value is assigned to the parallel coordinate axis in the mechanical analysis model coordinate system, and the target pipeline load value corresponding to the parallel coordinate axis direction is obtained, including: if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, the original pipeline load value corresponding to the horizontal axis direction of the pipeline system coordinate system in the original pipeline system load is assigned to the coordinate axis in the mechanical analysis model coordinate system and parallel to the horizontal axis direction; the original pipeline load value corresponding to the longitudinal axis direction of the pipeline system coordinate system in the original pipeline system load is assigned to the coordinate axis in the mechanical analysis model coordinate system and parallel to the longitudinal axis direction; the original pipeline load value corresponding to the vertical axis direction of the pipeline system coordinate system in the original pipeline system load is assigned to the coordinate axis in the mechanical analysis model coordinate system and parallel to the vertical axis direction.

[0086] Among them, the mechanical analysis model coordinate system and the pipeline system coordinate system are both spatial coordinate systems.

[0087] Specifically, the server can determine whether at least two of the horizontal axis, the vertical axis, and the vertical axis in the mechanical analysis model coordinate system are parallel to the coordinate axes of the pipeline system coordinate system. It can be understood that if the two coordinate axes in the two coordinate systems are parallel, it means that the two coordinate systems are parallel. If the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, the server can assign the original pipeline load value corresponding to the horizontal axis direction of the pipeline system coordinate system in the original pipeline system load to the coordinate axis parallel to the horizontal axis direction under the mechanical analysis model coordinate system. The server can assign the original pipeline load value corresponding to the vertical axis direction of the pipeline system coordinate system in the original pipeline system load to the coordinate axis parallel to the vertical axis direction under the mechanical analysis model coordinate system. The server can assign the original pipeline load value corresponding to the vertical axis direction of the pipeline system coordinate system in the original pipeline system load to the coordinate axis parallel to the vertical axis direction under the mechanical analysis model coordinate system to obtain the target pipeline system load.

[0088] In this embodiment, if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, the original pipeline load values ​​corresponding to the horizontal axis, longitudinal axis and vertical axis of the pipeline system coordinate system can be directly assigned to the corresponding coordinate axes under the mechanical analysis model coordinate system based on the parallel relationship between the pipeline system coordinate system and the mechanical analysis model coordinate system. There is no need to decompose and combine the original pipeline system load to obtain the target pipeline load value, which greatly reduces the cost of calculating the target pipeline load value.

[0089] In one embodiment, if the pipeline system coordinate system is parallel to the mechanical analysis model coordinate system, then for the original pipeline load value corresponding to each coordinate axis direction in the pipeline system coordinate system, the original pipeline load value is assigned to the parallel coordinate axis in the mechanical analysis model coordinate system, and the target pipeline load value corresponding to the parallel coordinate axis direction is obtained, including: if the number of coordinate axes in the pipeline system coordinate system is less than the number of coordinate axes in the mechanical analysis model coordinate system, the pipe clamp local coordinate system of the target pipe clamp corresponding to the original pipeline system load is determined; the target pipe clamp is used to connect the target support and the pipeline system; the number of coordinate axes in the pipe clamp local coordinate system is consistent with that in the mechanical analysis model coordinate system, and the pipe clamp local coordinate system includes coordinate axes parallel to each coordinate axis of the pipeline system coordinate system; if the pipe clamp local coordinate system is parallel to the mechanical analysis model coordinate system, then according to the parallel relationship between the pipeline system coordinate system and the pipe clamp local coordinate system, the original pipeline load value is assigned to the coordinate axis in the mechanical analysis model coordinate system and parallel to each coordinate axis of the pipe clamp local coordinate system, and the target pipeline load value corresponding to the parallel coordinate axis direction is obtained.

[0090] The pipe clamp local coordinate system is a local coordinate system established for the pipe clamp of the target support.

[0091] Specifically, if the number of coordinate axes of the pipeline system coordinate system is less than the number of coordinate axes of the mechanical analysis model coordinate system, the server can determine the local coordinate system of the target pipe clamp corresponding to the original pipeline system load from the geometric model of the support. It can be understood that the mechanical analysis model coordinate system is a spatial coordinate system, including a horizontal axis, a longitudinal axis and a vertical axis, while the support constraint directions of the support to the pipeline are less than 3. For example, the guide constraints of the support to the pipeline can be 2, and the original pipeline system load obtained at this time only includes two constraint directions; the sliding constraint of the support to the pipeline can be 1, and the original pipeline system load obtained at this time only includes one constraint direction. In essence, the pipeline system coordinate system is not a coordinate system established based on the physical components in the nuclear power plant, but is extracted from the original pipeline system load. For example, if the local coordinate system of the pipe clamp is parallel to the mechanical analysis model coordinate system, the server can assign the original pipeline load value to the coordinate axis under the mechanical analysis model coordinate system and parallel to the coordinate axes of the local coordinate system of the pipe clamp according to the parallel relationship between the pipeline system coordinate system and the local coordinate system of the pipe clamp, and obtain the target pipeline load value corresponding to the parallel coordinate axis direction.

[0092] In this embodiment, when the number of coordinate axes of the pipeline system coordinate system is less than the number of coordinate axes of the mechanical analysis model coordinate system, the pipe clamp local coordinate system can be used to replace the pipeline system coordinate system. If the pipe clamp local coordinate system is parallel to the mechanical analysis model coordinate system, then according to the parallel relationship between the pipeline system coordinate system and the pipe clamp local coordinate system, the original pipeline load value is assigned to the coordinate axis under the mechanical analysis model coordinate system and parallel to each coordinate axis of the pipe clamp local coordinate system, and the target pipeline load value corresponding to the parallel coordinate axis direction is obtained. There is no need to decompose and combine the original pipeline system load to obtain the target pipeline load value, which greatly reduces the cost of calculating the target pipeline load value.

[0093] In one embodiment, the method also includes: respectively determining the angles between each coordinate axis of the pipeline system coordinate system and each coordinate axis of the mechanical analysis model coordinate system to obtain multiple angles; judging whether at least two coordinate axes in the mechanical analysis model coordinate system are respectively parallel to the coordinate axes of the pipeline system coordinate system based on the multiple angles and a preset parallel angle error; if so, judging that the mechanical analysis model coordinate system is parallel to the pipeline system coordinate system.

[0094] Specifically, the server can determine the angles between each coordinate axis of the pipeline system coordinate system and each coordinate axis of the mechanical analysis model coordinate system according to the direction vector of the pipeline system coordinate system and the direction vector of the mechanical analysis model coordinate system, and obtain multiple angles. If the difference between the angle and the parallel angle is within the preset parallel angle error range, the server can determine that the two coordinate axes corresponding to the angle are parallel. It can be understood that the parallel angle is used to determine the angle of parallelism, such as 0 degrees and 180 degrees. The server can determine whether at least two coordinate axes in the mechanical analysis model coordinate system are parallel to the coordinate axes of the pipeline system coordinate system by comparing the difference between the angles of multiple angles and the parallel angle with the preset parallel angle error. If so, it is determined that the mechanical analysis model coordinate system is parallel to the pipeline system coordinate system. For example, if the preset parallel angle error is 2 degrees, no matter whether the angle is 182 degrees, 2 degrees or 178 degrees, the server can determine that the coordinate axes corresponding to the angle are parallel.

[0095] In one embodiment, the server may perform point-by-point multiplication of the direction vectors of the pipeline system coordinate system with the direction vectors of the mechanical analysis model coordinate system, calculate the cosine value of the angle between each coordinate axis of the pipeline system coordinate system and each coordinate axis of the mechanical analysis model coordinate system, and determine the angle corresponding to the cosine value.

[0097] in, and They are the horizontal axis direction vector, longitudinal axis direction vector and vertical axis direction vector of the pipeline system coordinate system respectively. and They are the horizontal axis direction vector, the vertical axis direction vector and the vertical axis direction vector of the mechanical analysis model coordinate system. ij It is the angle between the i-axis of the pipeline system coordinate system and the j-axis of the mechanical analysis model coordinate system. It can be understood that if the radian of the angle is equal to kπ, the two coordinate axes are considered to be parallel; if the radian of the angle is not equal to kπ, the two coordinate axes are considered to be non-parallel. k can be 0 or 1. The parallel angle error is considered in the judgment process, such as a parallel angle error of 2 degrees.

[0098] In one embodiment, the server may convert the original pipeline system load into the target pipeline system load in the mechanical analysis model coordinate system according to the conversion rules shown in Table 1. It can be understood that when the angle is 180 degrees, the two coordinate axes are parallel but in opposite directions. When the server assigns the original pipeline load value to the coordinate axis of the mechanical analysis model coordinate system, it uses the opposite direction of the corresponding coordinate axis to perform the assignment.

[0102] In this embodiment, the angles between each coordinate axis of the pipeline system coordinate system and each coordinate axis of the mechanical analysis model coordinate system are determined respectively to obtain multiple angles; based on the multiple angles and the preset parallel angle error, it is determined whether at least two coordinate axes in the mechanical analysis model coordinate system are respectively parallel to the coordinate axes of the pipeline system coordinate system; if so, it is determined that the mechanical analysis model coordinate system is parallel to the pipeline system coordinate system, so that the original pipeline system load can be converted to the target pipeline system load in the mechanical analysis model coordinate system to improve the accuracy of the mechanical analysis processing.

[0103] In one embodiment, the original pipeline system load includes the original pipeline load values ​​corresponding to the directions of each coordinate axis of the pipeline system coordinate system; converting the original pipeline system load into the target pipeline system load in the mechanical analysis model coordinate system includes: if the pipeline system coordinate system is not parallel to the mechanical analysis model coordinate system, then for the original pipeline load values ​​corresponding to the directions of each coordinate axis of the pipeline system coordinate system, the original pipeline load values ​​are decomposed and combined according to the directions of each coordinate axis of the mechanical analysis model coordinate system to obtain the load envelope values ​​in the directions of each coordinate axis of the mechanical analysis model coordinate system; the target pipeline system load in the mechanical analysis model coordinate system includes the load envelope values ​​in the directions of each coordinate axis of the mechanical analysis model coordinate system.

[0104] Specifically, if the pipeline system coordinate system is not parallel to the mechanical analysis model coordinate system, the server can decompose and combine the original pipeline load values ​​corresponding to the original pipeline load values ​​in the directions of the coordinate axes of the pipeline system coordinate system according to the directions of the coordinate axes of the mechanical analysis model coordinate system to obtain the load envelope values ​​in the directions of the coordinate axes of the mechanical analysis model coordinate system. It can be understood that the original pipeline system load includes force and moment. If the pipeline system coordinate system includes a horizontal axis, a vertical axis and a vertical axis, the force and moment of the original pipeline system load have maximum and minimum values ​​in the horizontal axis direction, the vertical axis direction and the vertical axis direction respectively. It can be understood that the original pipeline system load includes original pipeline load values ​​corresponding to 6 directions respectively, so there are 64 combinations of original pipeline load values. In fact, these 64 combinations cannot occur at the same time. Therefore, the server can determine the envelope value of the combination of 64 original pipeline load values ​​to obtain the load envelope value in the directions of the coordinate axes of the mechanical analysis model coordinate system.

[0105] In this embodiment, if the pipeline system coordinate system is not parallel to the mechanical analysis model coordinate system, the original pipeline load values ​​corresponding to the coordinate axis directions of the pipeline system coordinate system are decomposed and combined according to the coordinate axis directions of the mechanical analysis model coordinate system to obtain the load envelope values ​​in the coordinate axis directions of the mechanical analysis model coordinate system. Different calculation methods can be selected based on the mechanical model coordinate system to obtain the target pipeline system load. Compared with the method of directly using the global coordinate system to indiscriminately decompose and combine the original pipeline load to calculate the load envelope value, it can improve the accuracy while reducing the calculation cost of the target pipeline system load.

[0106] In one embodiment, the global coordinate system includes a horizontal axis, a vertical axis and a vertical axis; the coordinate axes that match each coordinate axis of the global coordinate system of the nuclear power plant are determined from the coordinate axes of the overall local coordinate system of the target support, and a mechanical analysis model coordinate system that is close to the direction of the global coordinate system is constructed according to the directions of the matched coordinate axes, including: from the coordinate axes of the overall local coordinate system of the target support, the coordinate axes that match the highest degree of each coordinate axis in the horizontal axis, the vertical axis and the vertical axis of the global coordinate system are determined; the direction of the horizontal axis of the mechanical analysis model coordinate system is determined according to the direction of the coordinate axis of the overall local coordinate system that matches the horizontal axis of the global coordinate system the highest; the direction of the vertical axis of the mechanical analysis model coordinate system is determined according to the direction of the coordinate axis of the overall local coordinate system that matches the vertical axis of the global coordinate system the highest; the direction of the vertical axis of the mechanical analysis model coordinate system is determined according to the direction of the coordinate axis of the overall local coordinate system that matches the vertical axis of the global coordinate system the highest; the direction of the vertical axis of the mechanical analysis model coordinate system is determined according to the direction of the coordinate axis of the overall local coordinate system that matches the vertical axis of the global coordinate system the highest, so as to construct a mechanical analysis model coordinate system that is close to the direction of the global coordinate system.

[0107] Specifically, the server can determine the coordinate axis with the highest degree of matching with each of the horizontal axis, vertical axis and vertical axis of the global coordinate system from the coordinate axis of the overall local coordinate system of the target support. The server can determine the direction vector information of the overall local coordinate system, and determine the direction vector information of the horizontal axis of the mechanical analysis model coordinate system according to the direction vector information of the coordinate axis of the overall local coordinate system with the highest degree of matching with the horizontal axis of the global coordinate system, determine the direction vector information of the vertical axis of the mechanical analysis model coordinate system according to the direction vector information of the coordinate axis of the overall local coordinate system with the highest degree of matching with the vertical axis of the global coordinate system, and determine the direction vector information of the vertical axis of the mechanical analysis model coordinate system according to the direction vector information of the coordinate axis of the overall local coordinate system with the highest degree of matching with the vertical axis of the global coordinate system, so as to construct a mechanical analysis model coordinate system close to the direction of the global coordinate system.

[0108] In this embodiment, coordinate axes matching each coordinate axis of the global coordinate system of the nuclear power plant are determined from the coordinate axes of the overall local coordinate system of the target support, and a mechanical analysis model coordinate system close to the direction of the global coordinate system is constructed according to the direction of the matching coordinate axes, so that the mechanical analysis processing of the target support can be performed based on the mechanical model coordinate system to improve accuracy. Furthermore, due to the high degree of matching between the mechanical analysis model coordinate system and the global coordinate system, the readability of the mechanical analysis model constructed based on the mechanical analysis model coordinate system is guaranteed.

[0109] In one embodiment, determining the coordinate axis that has the highest degree of matching with each of the horizontal, vertical and vertical axes of the global coordinate system from the coordinate axes of the overall local coordinate system of the target support comprises: calculating the direction cosine values ​​between the coordinate axis of the overall local coordinate system and each of the horizontal, vertical and vertical axes of the global coordinate system; determining the coordinate axis that has the largest absolute value of the direction cosine value with each coordinate axis of the global coordinate system from the coordinate axes of the overall local coordinate system, to obtain the coordinate axis that has the highest degree of matching with each coordinate axis of the global coordinate system.

[0110] Specifically, the degree of matching can be evaluated by the direction cosine value between the two coordinate axes. The server can respectively calculate the direction cosine value between the coordinate axis of the overall local coordinate system and each of the horizontal axis, vertical axis and vertical axis of the global coordinate system. It can be understood that the direction cosine value can evaluate the degree of matching between the two coordinate axes. The larger the absolute value of the direction cosine value, the closer the two coordinate axes are to parallel. The server can determine the coordinate axis with the largest absolute value of the direction cosine value for each coordinate axis of the global coordinate system from the coordinate axes of the overall local coordinate system, and obtain the coordinate axis with the highest degree of matching for each coordinate axis of the global coordinate system.

[0111] In this embodiment, the direction cosine value between the two coordinate axes is used to determine the coordinate axes that match each coordinate axis of the global coordinate system of the nuclear power plant from the coordinate axes of the overall local coordinate system of the target support, and a mechanical analysis model coordinate system close to the direction of the global coordinate system is constructed according to the direction of the matched coordinate axes, so that the mechanical analysis processing of the target support can be performed based on the mechanical model coordinate system to improve the accuracy. Furthermore, since the direction of the mechanical analysis model coordinate system is close to that of the global coordinate system, the readability of the mechanical analysis model constructed based on the mechanical analysis model coordinate system is guaranteed.

[0112] In one embodiment, the method also includes: obtaining direction vector information of the piping system coordinate system extracted from the original piping system load, and direction vector information of the overall local coordinate system of the target support; the direction vector information of the piping system coordinate system and the direction vector information of the overall local coordinate system are determined with the global coordinate system of the nuclear power plant as the reference coordinate system; respectively determining coordinate axes that match each coordinate axis of the global coordinate system of the nuclear power plant from the coordinate axes of the overall local coordinate system of the target support, and constructing a mechanical analysis model coordinate system that is close to the direction of the global coordinate system according to the directions of the matching coordinate axes, including: respectively calculating the degree of matching between the coordinate axes of the overall local coordinate system and each coordinate axis of the global coordinate system according to the direction of the coordinate axis with the highest degree of matching, and constructing a mechanical analysis model coordinate system that is close to the direction of the global coordinate system according to the directions of the coordinate axes with the highest degree of matching.

[0113] In one embodiment, the server can calculate the original pipeline system load of the pipeline system supported by the target support member for the geometric model of the target support member through the pipeline calculation program. The pipeline calculation program can calculate the original pipeline system load, and encapsulate the direction of the obtained original pipeline system load and the original pipeline load value of the corresponding direction into a load result file. The server can obtain the load result file, and extract the direction vector information of the original pipeline system load and the original pipeline load value of the corresponding direction vector from the load result file. Among them, the direction of the original pipeline system load is essentially the direction in which the support member applies the support constraint to the pipeline. The original pipeline system load is the load of the pipeline on the target support member. The pipeline calculation program can be a professional analysis of the pipeline in the geometric model. Software, used to calculate the load of the pipeline system on the target support member.

[0114] Specifically, the server can obtain the direction vector information of the original pipeline system load and the original pipeline system load value of the corresponding direction vector through the pipeline calculation program. The server can use the direction vector of the original pipeline system load as the direction vector of the coordinate axis of the pipeline system coordinate system. The server can obtain the direction vector information of the overall local coordinate system of the target support through the three-dimensional modeling platform. The server can determine the direction cosine values ​​of the coordinate axis of the overall local coordinate system and each coordinate axis of the global coordinate system from the direction vector information of the overall local coordinate system, and construct a mechanical analysis model coordinate system close to the direction of the global coordinate system according to the direction of the coordinate axis with the largest absolute value of the direction cosine value. It can be understood that the direction vector of the overall local coordinate system is obtained by taking the global coordinate system as the reference coordinate system, and the direction vector of the coordinate axis of the overall local coordinate system has the direction cosine value of each coordinate axis of the global coordinate system.

[0115] In one embodiment, Figure 3Schematic diagram of the overall local coordinate system, global coordinate system and pipeline system coordinate system in the geometric model shown. The server can determine the overall local coordinate system of the target support and the global coordinate system of the nuclear power plant through the three-dimensional modeling platform. The server can determine the pipeline system coordinate system through the pipeline calculation program. It can be understood that the overall local coordinate system is the coordinate system established by the three-dimensional modeling platform for the target support as a whole. The global coordinate system is the coordinate system established by the three-dimensional modeling platform for the nuclear power plant as a whole.

It can be understood that the support member supports and constrains the pipeline system through the pipe clamp, so the direction vector of the pipe clamp local coordinate system is usually parallel to the direction vector of the pipeline system coordinate system.
