Description

Technical Field

[0001] The present invention relates to the field of CAE simulation technology, and in particular to a CAE simulation analysis method for building interior optimization. Background Art

[0002] Computer-aided engineering (CAE), as an emerging discipline, has gradually come down from its pedestal and become an indispensable part of the new product design process of major companies. Traditional CAE technology refers to the analytical calculation and analytical simulation in engineering design, specifically including engineering numerical analysis, structural and process optimization design, strength and life assessment, motion / dynamics simulation, to verify the availability and reliability of future projects / products.

[0003] In the field of building interior structure optimization, CAE simulation analysis, as the core technology for evaluating the safety and stability of load-bearing systems, has always been the focus of industry attention due to its accuracy and efficiency.

[0004] The application with publication number CN108416129A discloses an integrated design method for prefabricated buildings based on BIM and PDM, aiming to provide an efficient integrated design method for prefabricated buildings based on BIM and PDM; the method comprises the following steps: step (1): installing SECR software on an architectural design end computer equipped with BIM software and a manufacturing design end computer equipped with PDM software and connecting them through a server; step (2): formulating coding rules for the parts of each component family of a building into general parts, special parts and non-standard parts, and coding the general parts and special parts under each family one by one; step (3): performing three-dimensional design on an architectural design end computer or a manufacturing design end computer; step (4): defining the materials and formulas of the parts of the three-dimensional model on the manufacturing design end computer; step (5): performing structural calculation of the parts based on PKPM.STS software for architectural structure calculation and mscnastran software for structural CAE simulation analysis and calculation of mechanical products.

[0005] The CAE simulation processing process for building interiors generally only focuses on the strength characteristics or stress characteristics between corresponding structural points, and does not effectively analyze the simulation conditions under sudden events in the corresponding buildings. The analysis process is not comprehensive enough and the accuracy is not high, which may lead to subsequent collapse of points between building structures due to misalignment. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the present invention provides a CAE simulation analysis method for building interior optimization, which solves the problems of insufficient comprehensiveness and low accuracy of the original simulation analysis process.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A CAE simulation analysis method for building interior optimization, comprising the following steps:

[0008] Step 1: Generate a building model associated with the corresponding building based on the architectural drawings associated with the corresponding building, then determine different bearing points within the building model, and lock the bearing points of the same category based on the different load-bearing characteristics associated with the different bearing points;

[0009] Among them, the specific methods for confirming the bearing points of the same classification are:

[0010] Based on the generated building model, confirm the relevant component models belonging to the load-bearing components;

[0011] Then confirm the contact points associated between the corresponding load-bearing component and other component models, mark the associated contact points as the corresponding load-bearing component's bearing points, and record the different bearing points generated by the same type of load-bearing component and the same group of other component models as the same classification bearing points;

[0012] Step 2: Based on the calibrated bearing points of the same classification, confirm the load-bearing characteristics associated with each bearing point, and lock the stress data of the corresponding bearing point from the confirmed load-bearing characteristics. Then, synchronize and verify the confirmed multiple sets of stress data to identify whether the bearing section meets the standards. The specific method of identification is as follows:

[0013] Confirm the bearing surface associated with the bearing point. If the bearing surface is circular, then confirm the cross-sectional area M (πr 2 ), if the load-bearing surface is a rectangle, the cross-sectional area M of the current load-bearing surface is determined based on the length and width of the rectangle. If the load-bearing surface is another polygon, the polygon segmentation method can be used to decompose the irregular polygon into triangles, and the area of ​​each basic figure is calculated separately, and the sum is used to obtain the total cross-sectional area M;

[0014] Then confirm the moment of inertia associated with the bearing point: calibrate the height of the load-bearing component associated with the corresponding bearing point as H: If the bearing surface is a rectangle, select the width b and height H of the rectangle to confirm the moment of inertia, and its moment of inertia = bH 3 ÷12; If the load-bearing surface is circular, the radius of the circle is marked as r, and the moment of inertia associated with the load-bearing surface = πr 4 ÷4; If the load-bearing surface is a triangle, then take the length of the longest side as b, and its moment of inertia = bH 3 ÷12; If the load-bearing surface is other polygons, the polygon segmentation method can be used to decompose the irregular polygon into triangles, and the moments of inertia of each can be calculated separately, and the total moment of inertia J can be obtained by summing them up;

[0015] From the constructed building model, identify the uniformly distributed load q associated with the load-bearing components. q is the preset value. Use: N = q × H to confirm the axial force N. H is the height of the corresponding load-bearing component. Then use: ZY = N ÷ M to confirm the axial normal stress ZY associated with the corresponding bearing point. Then use: (q × H 2 )÷2=P to confirm the top bending moment P, and use: (P×y)÷J=WY to confirm the bending normal stress WY associated with the corresponding anchor point, where y is the distance from the anchor point to the neutral axis, which can be directly obtained from the building model. Then use: ZL=WY+ZY to lock the total stress ZL associated with the corresponding anchor point;

[0016] The total stresses associated with other bearing points belonging to the same classification are recorded in sequence, and the variance of the recorded multiple total stresses ZL is processed to confirm the calibration variance Fc. If Fc≤Y1, it means that the current bearing section analysis meets the standard, where Y1 is the preset value. If Fc>Y1, it means that the current bearing section analysis does not meet the standard, and a stress difference signal is directly generated for display;

[0017] Step 3: For the load-bearing sections that meet the standards, perform dynamic verification on the building model. During the dynamic verification process, identify the stress change characteristics of the same classification of bearing points, and confirm whether the dynamic verification of the same classification of bearing points meets the standards based on the identified stress change characteristics. The specific method for confirmation is as follows:

[0018] Confirm the built-in center line of the building model, which can be directly confirmed from the building model, and make the building model perform angular offset according to the built-in center line. The built-in center line of the building model after the angular offset is recorded as the offset center line, and the original built-in center line is recorded as the built-in center line. After the offset process is completed, the angle associated with the offset center line and the built-in center line is 30 degrees. The initial position of the offset center line in the offset process is recorded. Then, the building model is controlled to rotate around the original built-in center line in the offset state, and stops when the corresponding offset center line rotates back to the initial position, completing a set of offset rotation processes.

[0019] During the offset rotation process, the total stress ZL associated with a single anchorage in the same classification anchorage is monitored in real time, and the maximum total stress and the minimum total stress are determined based on the real-time monitoring process, and the stress difference CZ is determined based on the maximum total stress and the minimum total stress. k , where k represents different bearing points, and the stress difference CZ of multiple different bearing points is k , perform variance processing, lock the variance to be verified, and compare the locked variance to be verified with the preset value Y2, where Y2 is the preset value. If the variance to be verified ≤ Y2, it means that the dynamic verification of the load-bearing section meets the standard; if the variance to be verified > Y2, it means that the dynamic verification of the load-bearing section does not meet the standard;

[0020] The verification process for this part also includes further confirmation methods:

[0021] The specific method is:

[0022] During the offset rotation process, the height status of each anchor point is monitored. The base surface of the building model is used as the reference surface to confirm the height data of the corresponding anchor point in real time during the rotation process, and the rotation stage in which the height data of the corresponding anchor point is at the lowest state is recorded. According to the different rotation stages confirmed for different anchor points, the total stress data associated with the corresponding anchor point in the corresponding rotation stage is confirmed, and the maximum total stress and the minimum total stress are selected from the confirmed total stress data. The stress difference CZ associated with the corresponding anchor point is confirmed from the selected maximum total stress and minimum total stress. k , and use the same confirmation and assessment method as the above-mentioned verification variance to identify whether the corresponding load-bearing section has met the dynamic verification standards, and generate relevant signals for display.

[0023] The present invention provides a CAE simulation analysis method for building interior optimization. Compared with the existing technology, it has the following advantages:

[0024] The present invention generates building models and intelligently calibrates the bearing points of the same classification, classifies and processes the contact points of load-bearing components according to their stress characteristics, and thus achieves systematic management of the bearing points of complex building structures, significantly improving the efficiency and pertinence of stress analysis and avoiding the tediousness of traditional single-point analysis.

[0025] In the stress calculation phase, a comprehensive stress model is constructed by combining parameters such as cross-sectional area and moment of inertia, and the variance of multiple sets of stress data is simultaneously verified. This not only ensures the accuracy of the coordinated analysis of axial stress and bending stress, but also quantitatively evaluates the stability of the load-bearing section through the degree of data dispersion, effectively identifying risk points of uneven stress distribution, and providing a quantitative basis for structural safety.

[0026] The dynamic verification process introduces a 30° offset rotation simulation of the building model, combined with the height status monitoring of the bearing points, to capture the extreme data of the most significant stage of stress characteristics. Compared with traditional static analysis, it is closer to the dynamic stress scenario of the building under actual loads (such as earthquakes and wind loads), and improves the accuracy of the assessment of the structure's anti-overturning capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 Schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 , this application provides a CAE simulation analysis method for building interior optimization, comprising the following steps:

[0030] Step 1. Generate an architectural model associated with the corresponding building based on the architectural drawings associated with the corresponding building (the method of generating a three-dimensional model of the corresponding building based on the drawings is relatively common in the prior art, so it will not be described in detail here. For example, the corresponding feature points are locked in each drawing, and the length, width and height features associated with the corresponding object features are simultaneously confirmed to generate a three-dimensional model of the corresponding object. Then, based on the position features and positional relationships between the corresponding three-dimensional models between the corresponding drawings, the architectural model associated with the corresponding building is generated). Then, different bearing points in the architectural model are determined, and based on the different load-bearing features associated with different bearing points, the bearing points of the same category are locked. Specifically, the bearing points are the contact points between different models. For example, the contact point between the load-bearing beam and the upper top is the corresponding bearing point. If the objects borne by the corresponding bearing points are the same above and below, then the bearing points associated with the same objects belong to the bearing points of the same category.

[0031] Among them, the specific methods for confirming the bearing points of the same classification are:

[0032] Based on the generated building model, the relevant component models belonging to the load-bearing components are confirmed. After the relevant component models are generated, the relevant operators will mark the relevant load-bearing components in advance;

[0033] Then confirm the contact points associated between the corresponding load-bearing component and other component models, mark the associated contact points as the corresponding load-bearing component's bearing points, and record the different bearing points generated by the same type of load-bearing component and the same group of other component models as the same classification bearing points;

[0034] For example, there are four support columns under the A component model. Each support column has a contact point with the A component model. The corresponding contact point is the corresponding anchor point. Therefore, the four contact points between the four support columns and the A component model are anchor points of the same category.

[0035] Step 2: Based on the calibrated bearing points of the same classification, confirm the load-bearing characteristics associated with each bearing point, and lock the stress data of the corresponding bearing point from the confirmed load-bearing characteristics. Then, synchronize and verify the confirmed multiple sets of stress data to identify whether the bearing section meets the standards. The specific method of identification is as follows:

[0036] Confirm the bearing surface associated with the bearing point. If the bearing surface is circular, then confirm the cross-sectional area M (πr 2 ), if the load-bearing surface is a rectangle, the cross-sectional area M of the current load-bearing surface is determined based on the length and width of the rectangle. If the load-bearing surface is another polygon, the polygon segmentation method can be used to decompose the irregular polygon into triangles, and the area of ​​each basic figure is calculated separately, and the sum is used to obtain the total cross-sectional area M;

[0037] Then confirm the moment of inertia associated with the bearing point: calibrate the height of the load-bearing component associated with the corresponding bearing point as H: If the bearing surface is a rectangle, select the width b of the rectangle (that is, the side with the smaller value) and the height H to confirm the moment of inertia, and its moment of inertia = bH 3 ÷12; If the load-bearing surface is circular, the radius of the circle is marked as r, and the moment of inertia associated with the load-bearing surface = πr 4 ÷4; If the load-bearing surface is a triangle, then take the length of the longest side as b, and its moment of inertia = bH 3 ÷12; If the load-bearing surface is other polygons, the polygon segmentation method can be used to decompose the irregular polygon into triangles, and the moments of inertia of each can be calculated separately, and the total moment of inertia J can be obtained by summing them up;

[0038] From the constructed building model, identify the uniformly distributed load q associated with the load-bearing components. q is a preset value, which is prepared in advance by the relevant operators based on the characteristics and parameters of the corresponding building materials. The axial force N is determined by: N = q × H, where H is the height of the corresponding load-bearing component. Then, the axial normal stress ZY associated with the corresponding bearing point is determined by: ZY = N ÷ M, and then the axial normal stress ZY associated with the corresponding bearing point is determined by: (q × H 2 )÷2=P to confirm the top bending moment P, and use: (P×y)÷J=WY to confirm the bending normal stress WY associated with the corresponding anchor point, where y is the distance from the anchor point to the neutral axis, which can be directly obtained from the building model. Then use: ZL=WY+ZY to lock the total stress ZL associated with the corresponding anchor point;

[0039] The total stresses associated with other bearing points belonging to the same classification are recorded in sequence, and the variance processing of the recorded multiple total stresses ZL is performed to confirm the calibration variance Fc. If Fc≤Y1, it means that the current bearing section analysis meets the standard. Y1 is a preset value, and its specific value is determined by the operator based on experience. If Fc>Y1, it means that the current bearing section analysis does not meet the standard. A stress difference signal is directly generated for display for external personnel to view. When external personnel view a signal with a large difference, they need to adjust the parameters and verify so that the stress data associated with the corresponding bearing section meets the standard.

[0040] Moreover, in the specific calculation process, stress needs to be comprehensively confirmed in combination with axial stress and bending stress. From the specific values ​​of comprehensive confirmation, the corresponding total stress is locked, and the characteristics of similar bearing points are verified in combination with the total stress. The numerical differences associated with the same type of features are identified, so as to achieve better numerical evaluation processing results.

[0041] Step 3: For the load-bearing sections that meet the standards, perform dynamic verification on the building model. During the dynamic verification process, identify the stress change characteristics of the same classification of bearing points, and confirm whether the dynamic verification of the same classification of bearing points meets the standards based on the identified stress change characteristics. The specific method for confirmation is as follows:

[0042] Confirm the built-in center line of the building model. The built-in center line can be directly confirmed from the building model. It is a center line inside the corresponding model. The building model is offset according to the built-in center line. The built-in center line of the building model after the angle offset is recorded as the offset center line, and the original built-in center line is recorded as the built-in center line. After the offset process is completed, the angle between the offset center line and the built-in center line is 30 degrees. The initial position of the offset center line in the offset process is recorded, and then the building model is controlled to rotate around the original built-in center line in the offset state until it rotates back to the corresponding offset center line. When it moves to the initial position, it stops and completes a set of offset rotation processes. Specifically, the corresponding building model needs to be tilted 30°. After the tilt, the center line of the corresponding building model is the offset center line, and the original center line position is the built-in center line. When the building model is in the offset rotation process, the corresponding offset center line will rotate along the built-in center line, and then an offset rotation process will be generated. In the corresponding offset rotation process, the offset center line will complete a movement process with an angle of 30° around the built-in center line, and rotate. That is to say, the corresponding building model will rotate an angle process;

[0043] During the offset rotation process, the total stress ZL associated with a single anchorage in the same classification anchorage is monitored in real time, and the maximum total stress and the minimum total stress are determined based on the real-time monitoring process, and the stress difference CZ is determined based on the maximum total stress and the minimum total stress.k , where k represents different bearing points, and the stress difference CZ of multiple different bearing points is k , perform variance processing, lock the variance to be verified, and compare the locked variance to be verified with the preset value Y2, where Y2 is the preset value, and its specific value is determined by the operator based on experience. If the variance to be verified ≤ Y2, it means that the dynamic verification of the load-bearing section meets the standard. If the variance to be verified > Y2, it means that the dynamic verification of the load-bearing section does not meet the standard, and a dynamic verification failure signal is directly generated for display. When external personnel find that there is a dynamic verification failure signal, they need to adjust and verify the positions of different load-bearing beams again, so that the corresponding dynamic verification process stops when it meets the standard, so that the corresponding load-bearing section meets the standard in the subsequent dynamic verification process;

[0044] The verification process for this part also includes further confirmation methods:

[0045] The specific method is:

[0046] During the offset rotation process, the height status of each anchoring point is monitored, and the base surface of the building model is used as the reference surface to confirm the height data of the corresponding anchoring point in real time during the rotation process, and record the rotation stage in which the height data of the corresponding anchoring point is at the lowest state (that is, among multiple anchoring points, the height data of this anchoring point is at the lowest value state, and its corresponding duration is the corresponding rotation stage). According to the different rotation stages confirmed by different anchoring points, the total stress data associated with the corresponding anchoring point in the corresponding rotation stage is confirmed, and the maximum total stress and the minimum total stress are selected from the confirmed total stress data, and the stress difference CZ associated with the corresponding anchoring point is confirmed from the selected maximum total stress and minimum total stress. k , and adopt the same confirmation and assessment method as the above-mentioned verification variance to identify whether the corresponding load-bearing section has met the dynamic verification standards, and generate relevant signals for display;

[0047] Specifically, compared with the above-mentioned processing process, the data processed in this processing process is more accurate, that is, the stress data corresponding to the bearing point is in the lowest value state. This lowest value state is the stage where the stress characteristics are most obvious. Therefore, compared with the accuracy of the above-mentioned stages, the stress difference associated with the corresponding stage has a higher accuracy in the rotation stage.

[0048] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0049] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
