Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0046] As described above, in current engineering construction, with the aging of old facilities and the application of new technologies, there will be more and more renovation and demolition projects for old buildings and facilities. In order to improve the reliability of safety analysis of demolition and modification projects, study the dynamic response characteristics of large structures during demolition and modification construction, and analyze the influence of different demolition sequences, demolition sizes, material properties and support methods on dynamic response, finite element simulation analysis technology is indispensable. ABAQUS is one of the most advanced large-scale general nonlinear finite element software in the world, which can handle very large and complex problems and simulate highly nonlinear problems. It can not only perform single-component mechanics and multi-physics analysis, but also perform system-level analysis and research. However, when using ABAQUS for demolition, the demolition unit to be demolished needs to be captured manually, and this capture method is extremely inefficient.

[0047] After research, it was found that in ABAQUS, there is a certain difference in the unit serial number between the demolition units that need to be demolished and the fixed parts that do not need to be demolished. The unit serial number of the fixed part of the constructed model is fixed and will not change with different demolition plans.

[0048] Before dismantling a structure or component, the order of dismantling must be determined. After the order is determined, the parts to be dismantled are divided into zones so that the dismantled parts can be transported from indoors to outdoors in a relatively suitable size, and the impact on the remaining structure is minimized when each zone is dismantled. Therefore, the zoning of the dismantled parts determines the economy and safety of the dismantling plan, and the method of automatically capturing the dismantled component units can improve the efficiency of finite element analysis, thereby relatively quickly selecting the optimal plan.

[0049] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] It is understandable that the method provided by the present application can be applied to a processing device, which is a processing device that can extract the unit number of the component unit in the file unit sequence of the INP file, for example, a terminal device or server that can extract the unit number of the component unit in the file unit sequence of the INP file. The method provided by the present application can be executed independently by a terminal device or a server, or it can be applied to a network scenario in which a terminal device and a server communicate, and is executed by the cooperation of a terminal device and a server. Among them, the terminal device can be a computer, a mobile phone or other device. The server can be understood as an application server or a Web server. In actual deployment, the server can be a stand-alone server or a cluster server.

[0051] Figure 1 A flowchart of a method for automatically capturing component units in a finite element model provided in the present application, the method comprising the following steps:

[0052] S101: extracting the unit number of the component unit in the file unit sequence of the INP file.

[0053] The processing device may extract the unit number of the component unit in the file unit sequence of the INP file.

[0054] The INP file is a bridge for data transfer between the early processor and the solver of the finite element analysis process. It is a text file with an extension of .inp generated based on keywords. The INP file is automatically generated by the CAE module of ABAQUS during the model simulation process and can be opened or modified by a text editing tool. The INP file contains all the features of a mathematical model. In this application, the INP file can include all the features in the engineering construction model. Therefore, the first step of this method is to extract the unit number of the component unit in the INP file. The component unit can be a component in the engineering construction model, and the component unit can be, for example, a structure such as a plate, a beam or a wall.

[0055] S102: Establishing a region matrix and an index dictionary based on the unit numbers.

[0056] The processing device establishes a region matrix and an index dictionary based on the unit number. The region matrix includes the correspondence between the component units in the target region and the unit attributes of the component units, and the index dictionary includes the correspondence between the unit number and the component unit.

[0057] For example, there are two walls in the target area, and the two walls have corresponding unit attributes, which may be the length, width, thickness, material and other attributes of the wall. Each wall has a corresponding unit number. The processing device can determine the correspondence between the two walls and the unit attributes based on the unit number, and represent each wall and the corresponding unit attribute in the form of an array to generate a regional matrix. The unit number corresponding to each wall in the regional matrix is ​​used as a mapping value, and the set of the two walls and the corresponding two mapping values ​​is used as an index dictionary.

[0058] Numerical Python, NumPy is an open source Python library that is widely used to perform numerical calculations. It provides a high-performance multidimensional array object (ndarray) and a wide range of tools for manipulating these arrays. ndarray is a multidimensional array with all elements of the same type. Compared with Python's native list, NumPy arrays are more efficient and optimized when storing and manipulating large data sets. Therefore, the core of the unit indexing method that considers geometric features is to create multiple matrices (i.e., two-dimensional arrays) corresponding to the length and width of the demolition component units through the NumPy library, and establish a dictionary index for each element in each matrix. The mapping value in the dictionary is the demolition component unit number corresponding to the matrix position.

[0059] In a possible implementation, the processing device may determine the correspondence between the plurality of component units and the unit length and unit width of the corresponding component units based on the unit number. Two-dimensional data corresponding to the plurality of component units and the unit length and unit width of the corresponding component units is created based on the NumPy library. A region matrix is ​​established based on the two-dimensional data. The unit number corresponding to each component unit in the region matrix is ​​used as a mapping value, and the set of the plurality of component units and the plurality of mapping values ​​is used as an index dictionary.

[0060] S103: Split the regional matrix into a demolition matrix and a fixed matrix.

[0061] The processing device divides the regional matrix into a removal matrix and a fixed matrix. The removal matrix includes a corresponding relationship between the removal unit and the unit attribute of the removal unit, and the fixed matrix includes a corresponding relationship between the fixed unit and the unit attribute of the fixed unit.

[0062] In a possible implementation, the processing device may divide the removal matrix again to obtain multiple removal sub-matrices. Because the fixed part unit serial number of the constructed model is fixed, the part to be removed can be processed in blocks. The processing device may divide the removal matrix into several removal sub-matrices to simulate the units to be removed each time.

[0063] For example, a two-dimensional array of size (10,10) is generated by the above method, which includes [4 3 14 3 8 3 6 5 5], [5 7 1 5 9 3 5 2 8 4], [8 3 8 6 1 7 6 1 6 0], [9 5 5 1 3 9 45 73], [1 4 9 7 1 2 9 6 3 7], [3 3 0 6 9 2 1 9 7 3], [6 3 3 2 9 7 0 3 7 1], [6 7 6 894 4 2 7 1], [9 5 5 1 9 2 3 7 4 7], and [0 5 8 7 3 1 2 7 2 3].

[0064] The reshape function can be used to convert the array into a one-dimensional array. After specifying the size of each group (assuming the size is 5), the split function is used to split the 5 data in each array. The array after splitting is as follows: [4,3,1,4,3], [8,3,6,5,5], [5,7,1,5,9], [3,5,2,8,4], [8,3,8,6,1], [7,6,1,6,0], [9,5,5,1 ,3],[9,4,5,7,3],[1,4,9,7,1],[2,9,6,3,7],[3,3,0,6,9],[2,1,9,7,3],[6,3,3,2,9],[7,0,3,7,1],[6,7,6,8,9],[4,4,2,7,1],[9,5,5,1,9],[2,3,7,4,7],[0,5,8,7,3] and [1,2,7,2,3].

[0065] S104: Generate a one-dimensional list corresponding to the demolition units at each demolition according to the demolition matrix and the index dictionary.

[0066] The processing device generates a one-dimensional list corresponding to the demolition units at each demolition according to the demolition matrix and the index dictionary.

[0067] In a possible implementation, the processing device may determine the unit number corresponding to the element value in the demolition matrix based on the index dictionary, generate a one-dimensional list of list type corresponding to the demolition unit at each demolition based on the element value and the corresponding unit number, and convert the one-dimensional list of list type into a one-dimensional list of geometry sequence type.

[0068] For example, the processing device can correspond the element values ​​(values ​​of unit attributes) in the demolition matrix to the unit numbers in the dictionary, and generate a one-dimensional list of the component units to be demolished each time. In ABAQUS, the collection reading type must be geometry sequence, and list type data cannot be read directly, so the one-dimensional list data needs to be converted to geometry sequence type.

[0069] S105: In the finite element model, a demolition plan corresponding to each demolition is simulated based on the demolition matrix, the fixed matrix and the one-dimensional list to obtain a demolition result.

[0070] The processing device can simulate the demolition plan corresponding to each demolition in the finite element model based on the demolition matrix, the fixed matrix and the one-dimensional list to obtain the demolition result, and the demolition result is used to represent the evaluation corresponding to the demolition plan.

[0071] In a possible implementation, there may be multiple demolition schemes for the demolition of the demolished components in the same target area. In order to find the optimal demolition scheme, the processing device can reconstruct the finite element model in multiple cycles to simulate different demolition schemes. At the beginning of the cycle, the current analysis step and the created demolition component unit set are deleted. In each cycle, according to the converted unit number, the set and the corresponding demolition analysis step are established in the demolition order. At the same time, the life and death unit is set in the contact to delete the corresponding component unit to be demolished, so as to realize the reconstruction of the calculation model, so as to perform analysis and calculation under different demolition schemes.

[0072] The regional matrix and index dictionary established in this application provide structured data information for the demolition project. This data structure clarifies the relationship between each component unit and its attributes, so that when simulating the demolition plan, the accuracy and consistency of the data can be ensured, and the errors caused by data confusion can be reduced. By segmenting the demolition matrix and the fixed matrix, a one-dimensional list of different demolition plans can be generated more flexibly. This flexibility allows managers to easily compare and evaluate the safety and effectiveness of different plans, minimizing the potential risks in the demolition process. Simulating the effect of each demolition in the finite element model can reflect the impact of different demolition plans on structural safety in real time. Unlike the prior art that only relies on static analysis, the dynamic simulation analysis of this application provides a more comprehensive and in-depth safety assessment, which helps managers make more scientific decisions in complex demolition environments. The method provided in this application can realize the automatic capture of demolition units by extracting the component unit numbers in the INP file and establishing a regional matrix and index dictionary based on these numbers. This process greatly reduces manual intervention and avoids the problem of inefficiency in manually capturing demolition units in the prior art, thereby significantly improving the overall efficiency of demolition plan generation.

[0073] This application also provides a Figure 2 The schematic structural diagram of the automatic capture device for removing a unit in a finite element model shown in FIG. 20 comprises the following modules:

[0079] The device provided by the present application, the established regional matrix and index dictionary provide structured data information for the demolition project. This data structure clarifies the relationship between each component unit and its attributes, so that when simulating the demolition plan, the accuracy and consistency of the data can be ensured, and the errors caused by data confusion can be reduced. By segmenting the demolition matrix and the fixed matrix, a one-dimensional list of different demolition plans can be generated more flexibly. This flexibility allows managers to easily compare and evaluate the safety and effectiveness of different plans, minimizing the potential risks in the demolition process.
