[0043] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0044] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0045] Embodiment One

[0046] The embodiment provides a diversified analysis method for a pipeline system. A core process includes 3D interaction, diversified analysis, queuing system and the like. Diversified analysis functions include defect-containing pipeline component analysis, thermal stratification analysis, LBB analysis, tee analysis and bellows analysis. Figure 1 and Figure 2 as shown, specifically comprising the following steps:

[0047] Step 1, the client creates a pipeline system mechanics model in response to a model creation instruction.

[0048] The method for creating the pipeline system mechanics model can be that, in response to a one-key import instruction clicked by a user on a graphical user interactive interface, a pipeline system solver input model is generated from a one-key import upstream pipeline perspective drawing, and a pipeline component mechanics model is automatically created to obtain the pipeline system mechanics model.

[0049] As shown in Figure 1 , the method for creating the pipeline system mechanics model can also be that, the client obtains a pipeline component unit and a modeling starting position selected by the user on the graphical user interactive interface, displays a parameter setting interface on the graphical user interactive interface, obtains pipeline component parameters (including a relative offset of a center line and section parameters) input by the user, completes detailed parameter definition, generates a pipeline component model, combines a plurality of pipeline component models into a pipeline system mechanics model (a pipeline component combined model), and saves a parameter file of the pipeline system mechanics model to a database system.

[0050] The pipeline component unit can be a straight pipe, an elbow pipe, a valve or a profile steel and the like.

[0051] The parameter file of the pipeline system mechanics model is saved in a tree-shaped data structure, one node corresponds to one pipeline component unit, and inherent attributes such as geometric parameters and material parameters are saved; for a pipeline system with a loop, a leaf node can point to an existing node in the tree, so that the tree-shaped data structure can process all pipeline systems; and a solver-independent neutral format is used for data saving. The client and the solver are decoupled, and the server side is adapted to the solver, which can reduce the workload of the solver adaptation and expand the application range of the embodiment.

[0052] The graphical user interface adopts the Office Ribbon-style menu bar. The creation idea of ​​the graphical user interface is: customize the QTabWidget and adjust the display style through QSS (style sheet); the central area of ​​the main window of the graphical user interface is the 3D display area of ​​the pipeline system mechanical model; different tabs of the graphical user interface correspond to different analysis functions.

[0053] The graphical user interface adopts the popular Office interface style, which takes into account both functionality and aesthetics and reduces the difficulty of use.

[0054] Step 2: The client renders the pipeline system mechanical model in response to the model rendering instruction.

[0055] The method for realizing the rendering function of the pipeline system mechanical model is as follows: the underlying engine is OpenGL; programmable pipeline technology is adopted; various display effects are developed based on the GLSL shader language, thereby performing 3D display and view operations on each pipe component unit, realizing the rendering of the pipeline system mechanical model; the Phong lighting model is adopted by default; the shader uses an external file method, which can be replaced without recompiling the program to achieve different rendering effects.

[0056] Step 3: In response to the analysis instruction, the client uploads the analysis task and the parameter files of the pipeline system mechanical model to the server in sequence.

[0057] like Figure 9 As shown, the client responds to the analysis instruction and connects to the server. If the connection fails, a prompt pops up; if the connection is successful, the analysis task is uploaded, and the queue status is obtained from the server, and the queue table of the graphical user interface is updated; the pipeline system mechanical model selected by the user in the graphical user interface is obtained, and the user information, client name and parameter file of the pipeline system mechanical model are uploaded to the server.

[0058] Analysis commands can include mechanical analysis, defective piping component analysis, thermal delamination analysis, LBB analysis, tee analysis, or bellows analysis. Different tabs in the graphical user interface correspond to different analysis functions. Users click analysis buttons on different tabs in the graphical user interface to generate different analysis commands.

[0059] Step 4: In response to the analysis task uploaded by the client, the server locks the thread; in response to the parameter file of the pipeline system mechanical model uploaded by the client, the server queues the analysis task and then unlocks the thread.

[0060] Step 5, the server reads the head of the queue, calls the analysis program corresponding to the analysis task through the solver interface corresponding to the analysis task, and performs static / dynamic and other conventional mechanical analysis or diversified analysis on the parameter file of the pipe system mechanical model to obtain the analysis result. During the mechanical analysis or diversified analysis, the analysis state of the analysis task corresponding to the head is changed to in calculation (or in analysis), and the analysis state is queried regularly. When the analysis state is changed to calculation complete (or analysis complete), the head of the queue is dequeued, the flag of the analysis task is changed to completed, and the queue is updated.

[0061] The analysis task can be mechanical analysis of the pipe system mechanical model, and diversified analysis of the pipe system mechanical model including defect pipe component analysis, thermal stratification analysis, and LBB analysis, and tee analysis and bellows analysis of the pipe component model. As shown in Figure 3 The diversified analysis is a series of multidisciplinary evaluations based on the mechanical analysis of the pipe system mechanical model, including defect pipe component analysis, thermal stratification analysis, LBB analysis, tee analysis, and bellows analysis. The defect pipe component analysis includes limit load, J / K analysis, fatigue crack propagation, and crack stability (including stability under limit condition, tearing stability, and double criterion stability); the thermal stratification analysis includes overall bending moment and overall bending stress, local film stress, local bending stress, and peak stress along the wall thickness; the LBB analysis is to obtain the LBB boundary curve of the pipe component model; the tee analysis includes stress evaluation and temperature field analysis; and the bellows analysis includes displacement evaluation, stress evaluation, fatigue, and stability. The diversified analysis depends on the parameters of the pipe component or pipe component combination model, such as geometry and material, and also depends on the calculation results of the conventional mechanical analysis of the pipe system.

[0062] The analysis program (solver) includes the mechanical analysis program of the pipe system mechanical model, the defect pipe component analysis program of the pipe component model, the thermal stratification analysis program of the pipe component combination model, the LBB analysis program of the pipe component combination model, the tee analysis program of the pipe component model, and the bellows analysis program of the pipe component model.

[0063] As shown in Figure 4As shown in the figure, the process of analyzing defective pipeline components is as follows: pick up the pipe component model to be analyzed and determine whether the pipe component model is of the specified type; if all pipe component models are of the specified type, obtain the crack parameters; based on the crack parameters, perform rapid fracture analysis (obtain the maximum bending moment of the pipe component model), fatigue crack growth (obtain the axial force and vertical bending moment of the pipe component model under various working conditions), tear stability analysis (obtain three times the maximum bending moment of the pipe component model), and ultimate load method analysis (calculate the ultimate load of the pipe component model based on the set material strength parameters); input the parameter file generated based on the results of rapid fracture analysis, fatigue crack growth, and tear stability analysis into the PFACrack program (a parametric automatic finite element mesh generation program for fracture mechanics finite element analysis of defective pipeline components), and combine the results output by PFACrack with the results of the ultimate load method analysis to form the key results.

[0064] like Figure 5 As shown in the figure, the process of LBB analysis is as follows: obtain the working condition list of single working condition and combined working condition and the set number of analysis pipe sections; obtain the starting and ending pipe component models of each pipe section in the pipeline system mechanical model selected by the user; select a single working condition, select the normal stress and maximum stress working conditions, and generate a json format parameter file; call the LBB analysis program to obtain key results.

[0065] like Figure 6 As shown, the process of thermal stratification analysis is as follows: pick up several pipe component models; determine whether the picked pipe component models are continuous. If so, traverse the pipe component models and mark the nodes corresponding to each pipe component model as a main pipe or branch pipe; determine whether each pipe component model is a specific component such as a pipe tee, elbow, reducer, flange or valve, and if so, mark the node corresponding to the pipe component model as a specific component; determine the geometric relationship between all marked pipe component models, call the thermal stratification analysis program, and obtain key results.

[0066] like Figure 7 As shown in the figure, the process of bellows analysis is: pick up the pipe component model (bellows unit) that belongs to the bellows assessment object; obtain the bellows specification parameters, and calculate the result of the straight edge segment length Lt / wavelength q; obtain the selected material and working conditions, obtain the force and bending moment values ​​of the starting and end points, generate a text format parameter file, and then call the bellows analysis program to obtain the key results.

[0067] like Figure 8 As shown in the figure, the process of tee analysis is as follows: pick up the pipe component model belonging to the tee; obtain the tee specification parameters, generate the parameter file, call the tee analysis program, and obtain the key results.

[0068] Because the computer power of the client is limited and the solver license is limited, the solver is deployed on a remote server, and the remote server and the client realize data interaction through a queuing system. The queuing system supports local submission, remote queuing and calculation result download of the calculation and analysis task. The queuing system developed by the application adopts a CS architecture, the client is used for task submission, monitoring, data download and task priority adjustment, the server is used for task queue management and interaction with the solver. The queuing system supports command line operation and supports batch processing automation to create tasks.

[0069] The core of the diversified analysis is the interface with each analysis program, the transmission of parameters to each analysis program, the generation of a calculation model by calling each analysis program, the submission of a solving task through a queuing system, the post-processing by calling each analysis program, and the display of key indicators.

[0070] The application adopts different interface technologies to realize the interaction between the server and the solver for different types of analysis programs. If the analysis program is a white box program, a file parameter transmission mode is adopted for data interaction. If the analysis program is a black box program, a Hook technology is adopted to simulate keyboard input for data interaction.

[0071] The queuing system in the application is designed to decouple the solver, which is convenient for adapting to the solver interface in diversified analysis. Relying on a database, the application manages the pipeline stereogram (a pipeline system mechanical model), a pipe component model, analysis results, diversified analysis input and output based on a project management system in the form of a project version. The diversified analysis mainly includes data transmission with each diversified analysis program, linkage analysis iteration and diversified analysis result display.

[0072] Step 6, the server returns the analysis result (key result) to the client, and the client renders the analysis result to the pipeline system mechanical model for 3D display.

[0073] The graphical user interface of the embodiment supports 3D visualization of the analysis result, adopts a set of common 3D display functions such as a cloud chart and deformation animation, and supports integration of more analysis programs.

[0074] Because the 3D rendering of the pipeline system mechanical model is needed, the pipeline system mechanical model needs to be meshed, and each pipe component unit corresponds to a triangular meshing algorithm. Key results usually include displacement, stress, modal, fatigue and other data, which are displayed through 3D, and the results can be displayed vividly. For the visualization display of displacement, the extracted node displacement is added to the coordinates of the original node, and the deformed mesh is regenerated. The deformed pipeline system mechanical model can be rendered by using the OpenGL framework, and the center line mode and the surface mode are supported. The stress display is visualized by using a cloud chart, and the cloud chart is realized by using a 1D texture. The modal display is realized by using an animation to display the vibration mode. The extracted node displacement is smoothed and interpolated to generate an intermediate state model, and the dynamic display of the vibration mode is realized by using a time component. The fatigue data is presented in the form of a table.

[0075] Step 7, as shown in Figure 10 The server end also listens to the analysis state request of the client end, that is, the client end requests the queue state, and the server end feeds back the queue state to the client end.

[0076] Step 8, in response to the parameter file download request of the pipeline system mechanical model of the client end, the permission of the client end is queried and verified, and the parameter file is returned to the client end after verification.

[0077] Step 8, in response to the analysis task deletion request of the client end, the permission of the client end is queried and verified, and the analysis task (including the data table and the parameter file) is deleted in the queue after verification.

[0078] Step 9, in response to the priority adjustment request of the analysis task of the client end, the permission of the client end is queried and verified, the thread is locked after verification, the order of the analysis task in the queue is adjusted, and the thread is unlocked.

[0079] The pipeline system-oriented diversified analysis method provided in this embodiment takes a database system, a queuing system and a project management system as support.

[0080] The pipeline system-oriented diversified analysis method provided in this embodiment, the user only needs to complete various analysis tasks in a graphical user interface, and the input and output data of each step can be traced with the assistance of the project management module, which greatly improves the mechanical analysis efficiency and reliability of the pipeline, and also reduces the learning cost of various diversified analysis tools.

[0081] The data structure and tool of the pipeline system-oriented diversified analysis method provided in this embodiment are independent of each other, and can be quickly adapted to the solver of the pipeline analysis and the diversified analysis tool through the interface, and have good expansibility.

[0082] The pipeline system-oriented diversified analysis method provided in the embodiment uses an Office-style graphical interface and a 3D interactive display mode, integrates the functions of pipeline system mechanical analysis, defect-containing pipeline component analysis, thermal stratification analysis, LBB analysis and other diversified analysis, breaks through the data island of each process, and thereby reduces the use difficulty of software in each process, solidifies the analysis process, and improves the analysis efficiency.
