[0071] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0072] The present application provides a structural design simulation analysis method. In the first embodiment of the structural design simulation analysis method of the present application, referring to Figure 1 , the structural design simulation analysis method includes:

[0073] Step S10, obtaining an effective structural model to be analyzed, performing grid discretization matching processing on the effective structural model, and obtaining grid units divided by the effective structural model;

[0074] Step S20, obtaining a simulated working condition of the effective structural model, and performing simulation analysis on the effective structural model based on the simulated working condition to obtain first simulation data of the grid unit connection under each of the simulated working conditions;

[0075] Step S30, based on the pre-classified working condition types of the simulated working condition, reducing the amount of simulation data in the first simulation data, obtaining the data to be analyzed for each working condition type, integrating and analyzing the data to be analyzed, and obtaining the simulation analysis results of the effective structural model.

[0076] In this embodiment, the specific application scenario may be:

[0077] To analyze the ultimate force that a certain structure of an automobile can withstand under different working conditions, it is necessary to simulate and analyze the effective structural model of the structure. Due to the different connection methods between structures, the connection method when creating the effective structural model is single, and the analysis of the effective structural model cannot be very close to reality, resulting in low accuracy of the structural analysis results.

[0078] Mechanical structure inspection in a machine, when conducting safety inspections on the machine under different operating conditions, requires modeling of the structure to be inspected in the machine and performing simulation analysis on the model of the structure to be inspected. During the analysis process, a large amount of data needs to be analyzed, which is prone to errors and results in low accuracy of the structural analysis.

[0079] This embodiment generally analyzes the simulation analysis results of the effective structural model by reducing the simulation data to be analyzed. Specifically, by analyzing the simulated operating conditions of different operating condition types, unnecessary data in the first simulation data of the effective structural model is reduced, the data to be analyzed in the first simulation data is determined, and the simulation analysis results of the effective structural model are analyzed from the data to be analyzed. Specifically, once the data to be analyzed in the first simulation data of the effective structural model is determined, the simulation analysis results of the effective structural model can be analyzed.

[0080] At present, in the method of structural design simulation analysis, when analyzing the effective structural model, all the first simulation data obtained from the analysis of the effective structural model are analyzed, which increases the amount of data analysis and is prone to data analysis errors during the analysis process. In the present application, the simulation analysis results of the effective structural model are obtained by screening the first simulation data, and the data to be analyzed are obtained by analyzing the data to be analyzed. The simulation analysis results of the effective structural model are analyzed, thereby reducing the amount of analysis of the first simulation data.

[0081] The specific steps are as follows:

[0082] Step S10, obtaining an effective structural model to be analyzed, performing grid discretization matching processing on the effective structural model, and obtaining grid units divided by the effective structural model;

[0083] In this embodiment, it should be noted that the structural design simulation analysis method can be applied to a structural design simulation analysis device, which belongs to a structural design simulation analysis equipment, and the structural design simulation analysis equipment belongs to a structural design simulation analysis equipment system.

[0084] For the structural design simulation analysis system, it should be noted that the effective structural model is a visual model created by modeling software.

[0085] It should be noted that the structural design simulation analysis is to obtain the unit analysis data of the grid unit by analyzing the grid unit, and then integrate and analyze the unit analysis data to obtain the simulation analysis results of the effective structural model.

[0086] Among them, the grid unit is the model block into which the effective structural model is divided by the grid.

[0087] The grid units must fit the effective structural model.

[0088] The effective structural model can be a 2D model or a 3D model.

[0089] It should be noted that the grid unit image must correspond to the effective structural model, that is, if the effective structural model is a 2D model, the grid unit is also a 2D model; if the effective structural model is a 3D model, the grid unit is also a 3D model.

[0090] For example, a rectangular model with an area of 6 is further divided by a grid with an area of 1 for each grid, and 6 rectangular units with an area of 1 are obtained. That is, the rectangular model is a valid structural model and the rectangular unit is a grid unit.

[0091] In this embodiment, an effective structural model to be analyzed is obtained, a grid discretization matching process is performed on the effective structural model, and the effective structural model is divided into a plurality of grid units through the grid.

[0092] Specifically, the steps of obtaining the effective structural model to be analyzed, performing grid discretization matching processing on the effective structural model, and obtaining grid units of the gridded effective structural model include:

[0093] Step S11, obtaining a valid structural model to be analyzed, and determining the simulation accuracy required for the simulation analysis;

[0094] Step S12, determining the size of a grid for dividing the effective structural model based on the simulation accuracy;

[0095] Step S13: Based on the size of the divided grid, a fine grid discretization matching process is performed on the effective structure model to obtain grid units of the effective structure model.

[0096] It should be noted that the accuracy required for simulation analysis is the target accuracy. When performing simulation analysis on an effective structural model, the simulation analysis results may not reach the target accuracy due to various reasons.

[0097] The size of the divided grid can be determined based on the simulation accuracy required by the simulation analysis results through the "grid number-accuracy" table, or it can be determined based on the simulation accuracy through the network size specifications within the industry.

[0098] In this embodiment, the effective structural model to be analyzed is obtained, wherein the method of obtaining the effective structural model may be:

[0099] Method 1: It can be data transmission, in which the effective structural model is transmitted to obtain the effective structural model to be analyzed.

[0100] Method 2: The structure to be analyzed can be modeled using modeling software based on rigid coupling unit connections and flexible coupling unit connections to obtain an effective structural model to be analyzed that fits the actual situation.

[0101] In this embodiment, the effective structural model to be analyzed is obtained, and the simulation accuracy required for the simulation analysis is determined. Based on the simulation accuracy, the size of the divided grid is determined by different methods. The effective structural model is meshed by meshing to obtain the mesh units of the effective structural model.

[0102] For example, the structure to be analyzed is modeled through modeling to obtain an effective structural model, and the simulation accuracy required for simulation analysis is determined. Based on the simulation accuracy, the size of the grid is determined through the network size specifications within the industry. Based on the size of the grid, the effective structural model is meshed to obtain fine grid units of the effective structural model.

[0103] In this embodiment, the effective structural model to be analyzed is obtained, and based on the simulation accuracy required for the simulation analysis, the size of the grid is determined, and the effective structural model is divided into grid units of the grid size by grid division.

[0104] Step S20, obtaining a simulated working condition of the effective structural model, and performing simulation analysis on the effective structural model based on the simulated working condition to obtain first simulation data of the grid unit connection under each of the simulated working conditions;

[0105] The simulated working condition is to simulate the working condition of the structure to be analyzed.

[0106] For example, the working condition of the suspension bracket can be simulated when the car is stationary, or the working condition of the suspension bracket can be simulated when the car is accelerating forward.

[0107] Among them, the grid units are connected through a certain connection method.

[0108] In this embodiment, the working conditions that need to be simulated for the structure to be analyzed, i.e., the simulated working conditions, are determined. Based on the simulated working conditions, the working conditions of the effective structural model are simulated, and the simulation of the working conditions of the effective structural model is analyzed to obtain the first simulation data at the connection of the grid units under each working condition.

[0109] Specifically, the steps of obtaining a simulated working condition of the effective structural model, performing simulation analysis on the effective structural model based on the simulated working condition, and obtaining first simulation data of the grid unit connection under each of the simulated working conditions include:

[0110] Step S21, obtaining a simulated working condition of the effective structural model, and analyzing the effective structural model based on the simulated working condition to obtain first analysis data of the first force concentration point and second analysis data of the second force concentration point;

[0111] Step S22: integrating and analyzing the first analysis data and the second analysis data to obtain first simulation data of each grid unit in each simulation working condition.

[0112] The rigid coupling unit connection is used to connect the units into one body without movement, that is, after the two units are connected into one body through the rigid coupling unit, the units are fixed.

[0113] The flexible coupling unit connection is used to movably connect the units into one body, that is, after the two units are connected into one body through the flexible coupling unit, the units are movable.

[0114] In this embodiment, a simulated working condition of the structure to be analyzed is obtained. In the process of simulating the working condition of the effective structural model, the first analysis data of the first force concentration point at the connection of the grid unit connected by two rigid coupling units and the second analysis data of the second force concentration point at the connection of the grid unit connected by two flexible coupling units are analyzed. That is, the first analysis data and the second analysis data are integrated to obtain the first simulation data of each of the grid units in each of the simulated working conditions.

[0115] Here, since each grid unit is connected to multiple grid units, and the connection between each grid unit and multiple grid units includes at least one connection mode, it may also include two connection modes.

[0116] In this embodiment, obtaining the structure to be analyzed requires simulating working conditions. During the simulation process of the structure to be analyzed for the simulated working conditions, first simulation data at the connection of each grid unit in the effective structural model is analyzed.

[0117] Step S30, based on the pre-classified working condition types of the simulated working condition, reducing the amount of simulation data in the first simulation data, obtaining the data to be analyzed for each working condition type, integrating and analyzing the data to be analyzed, and obtaining the simulation analysis results of the effective structural model.

[0118] The operating condition type includes at least one of a typical operating condition type, an extreme operating condition type, and a destructive operating condition type.

[0119] The classification of the simulated working conditions is based on the user's experience.

[0120] In this embodiment, the first simulation data is classified accordingly based on the working condition type to obtain second simulation data for each simulated working condition, and the data to be analyzed is screened out from the second simulation data. By analyzing the data to be analyzed, the simulation analysis results of the effective structural model are obtained.

[0121] In this embodiment, an effective structural model to be analyzed is obtained, and the connections of the grid units obtained after grid discretization matching processing of the effective structural model are analyzed to obtain first simulation data. The first simulation data is screened to obtain the data to be analyzed for each type of working condition. By analyzing the data to be analyzed, the simulation analysis results of the effective structural model are obtained.

[0122] The present application provides a structural design simulation analysis method, apparatus, equipment and storage medium. In the present application, an effective structural model to be analyzed is obtained, and a grid discretization matching process is performed on the effective structural model to obtain grid units divided by the effective structural model; a simulation working condition of the effective structural model is obtained, and based on the simulation working condition, a simulation analysis is performed on the effective structural model to obtain first simulation data of the grid unit connection under each of the simulation working conditions; based on the working condition type pre-classified for the simulation working condition, the amount of simulation data in the first simulation data is reduced to obtain data to be analyzed for each working condition type, and the data to be analyzed are integrated and analyzed to obtain simulation analysis results of the effective structural model. In the present application, based on the preset simulation working conditions, the effective structural model of the structure to be analyzed is simulated and analyzed to obtain the first simulation data at the connection of the grid units after the effective structural model is divided. Based on the working condition type classified by the simulation working condition, the simulation data in the first simulation data is reduced to obtain the data to be analyzed for each working condition type. The data to be analyzed are integrated and analyzed to obtain the simulation analysis results of the effective structural model. That is, in the present application, the actual structural state is accurately expressed by the effective structural model. Based on the working condition type, the data to be analyzed in the first simulation data is reduced. Therefore, the error rate of the simulation analysis is reduced and the accuracy of the structural design simulation analysis results is improved.

[0123] Further, based on the above embodiment of the present application, another embodiment of the present application is provided. In this embodiment, referring to Figure 2 The steps of reducing the amount of simulation data in the first simulation data based on the pre-classified working condition types of the simulated working condition, obtaining the data to be analyzed for each working condition type, and integrating and analyzing the data to be analyzed to obtain the simulation analysis results of the effective structural model include:

[0124] Step A10: sorting and classifying the first simulation data based on the pre-classified working condition types of the simulated working conditions to obtain second simulation data for each working condition type in the first simulation data;

[0125] In this embodiment, the first simulation data is sorted and classified based on the operating condition type. For example, the first simulation data corresponding to the simulated operating condition in the typical operating condition type is classified as the second simulation data of the typical operating condition type.

[0126] Step A20, analyzing the second simulation data based on a preset coordinate system and the coordinate axes of the coordinate system to obtain a maximum force value in each direction of the coordinate axis;

[0127] The second simulation data at least includes the displacement of the effective structural model under the simulated working condition.

[0128] Specifically, the step of analyzing the second simulation data based on a preset coordinate system and the coordinate axes of the coordinate system to obtain a maximum force value in the direction of the coordinate axis having the maximum force includes:

[0129] Step A21: performing displacement analysis on the second simulation data based on a preset coordinate system and the coordinate axes of the coordinate system to obtain a displacement in each direction of the coordinate axis;

[0130] Step A22: performing force calculation on the effective structural model based on the displacement to obtain a first force value in each direction of the coordinate axis;

[0131] Step A23: Compare the first force values in each same direction to obtain the maximum force value in each coordinate axis direction.

[0132] Among them, the displacement in each direction of the coordinate axis is the displacement of the effective structural model under the simulation of the working condition, and the displacement of the decomposed displacement in the direction of the coordinate axis.

[0133] In this embodiment, the second simulation data is analyzed to obtain the displacement in each direction of the preset coordinate axis. The first force value in each direction of the coordinate axis is obtained through the displacement. The first force value of each simulated working condition in the same coordinate axis direction in the working condition type corresponding to the second simulation data is compared to obtain the maximum force value with the largest force in each coordinate axis direction.

[0134] In this embodiment, the second simulation data is analyzed based on the preset coordinate system and the coordinate axis of the coordinate system, that is, the first force value of each simulated working condition in each coordinate axis direction in the second simulation data is analyzed, and the first force values in the same direction are compared to obtain the maximum force value with the largest force in each coordinate direction, wherein the maximum force value is the maximum force value with the largest force in each coordinate direction in a certain working condition type.

[0135] Step A30: obtaining data to be analyzed corresponding to the simulated working condition in the second simulation data based on the maximum force value;

[0136] In this embodiment, based on the maximum force value, the data to be analyzed of the simulated working condition in the working condition type corresponding to the maximum force value is obtained, that is, the data to be analyzed corresponding to the simulated working condition in the second simulation data is obtained.

[0137] Step A40, performing integration analysis on the data to be analyzed to obtain unit analysis data of the grid unit;

[0138] Specifically, the step of integrating and analyzing the data to be analyzed to obtain the unit analysis data of the grid unit includes:

[0139] Step A41, performing integrated analysis and calculation processing on the data to be analyzed to obtain a first stress value required for simulation analysis of the effective structural model based on the working condition type;

[0140] Step A42: Evaluate the first stress value to obtain unit analysis data of the grid unit.

[0141] In this embodiment, the data to be analyzed is computationally processed to obtain the first stress value required for analyzing the effective structural model under each operating condition type, and the first stress value is evaluated to obtain unit analysis data of the grid unit.

[0142] In this embodiment, the data to be analyzed are analyzed to obtain the grid unit analysis data of the mechanism model under the extreme conditions, wherein the data to be analyzed are the necessary data required to obtain the extreme value of the structure to be analyzed.

[0143] Step A50: integrating and analyzing the unit analysis data to obtain simulation analysis results of the effective structural model.

[0144] In this embodiment, the unit analysis data of the grid units are coordinated and integrated to obtain the simulation analysis results of the effective structural model.

[0145] In this embodiment, the first simulation data is sorted and classified based on the operating condition type to obtain second simulation data for each operating condition type. The second simulation data is then calculated and analyzed to obtain the maximum force value in each direction for each simulated operating condition within the same operating condition type. The data to be analyzed for the simulated operating condition corresponding to the maximum force value is then obtained. The data to be analyzed is then analyzed to obtain unit analysis data for each grid unit. The unit analysis data is then coordinated and integrated to obtain simulation analysis results for an effective structural model. In this embodiment, by reducing the amount of data to be analyzed, the probability of analysis errors is reduced, thereby improving the accuracy of the structural design simulation analysis results.

[0146] Furthermore, based on the above embodiment of the present application, another embodiment of the present application is provided. In this embodiment, before the step of obtaining the simulated working condition of the effective structural model, the method includes:

[0147] Step B10, analyzing the grid units to determine the connection types between the grid units;

[0148] Wherein, the connection types include rigid coupling unit connection and flexible coupling unit connection;
