[0024] Term Explanation:

[0025] LS-DYNA is a globally leading explicit dynamics finite element analysis (FEA) software, widely used in simulating complex physical phenomena, especially in the fields of collision, impact, explosion, metal forming, etc. It was developed by Livermore Software Technology Corporation (LSTC) in the United States and was initially based on the DYNA3D code of Lawrence Livermore National Laboratory (LLNL).

[0026] In a meta-analysis, data extraction is a crucial step, which involves extracting relevant information from the selected studies for subsequent data analysis and synthesis. The following are the specific steps for meta-analysis data extraction: Determine the data sources for the meta-analysis. The data sources for a meta-analysis are usually published scientific research literatures. These literatures can be obtained through database searches (such as PubMed, Web of Science, etc.), reference tracing, and manual searching. Ensuring the comprehensiveness and representativeness of the data sources is the prerequisite for data extraction; Select appropriate data extraction tools or methods. To efficiently extract data, appropriate data extraction tools or methods can be selected. For example, use literature management software (such as EndNote, Zotero, etc.) to manage the literatures and record the key information during the extraction process. In addition, formulating a standardized data extraction form is also an effective method, which can help researchers clarify the data fields to be extracted and maintain the consistency of data extraction; Extract the required data fields according to the meta-analysis specifications. When extracting data, it is necessary to follow the meta-analysis specifications to ensure that the extracted data fields meet the analysis requirements. Generally, the data fields to be extracted include the basic information of the study (such as author, publication year, research type, etc.), sample characteristics (such as age, gender, sample size, etc.), intervention measures and control group information, outcome indicators (such as mean, standard deviation, ratio, etc.), and statistical data (such as P-value, confidence interval, etc.).

[0027] The inventor's research found that: In the relevant tests of CNCAP (China New Car Assessment Program), CIASI (China Insurance Automotive Safety Index), and national standards (national standards), for the assessment of side collisions, it usually involves the performance of the vehicle structure in side collisions, aiming to ensure that the vehicle can effectively protect the safety of the occupants inside the vehicle during a side collision. A moving obstacle (such as a simulated vehicle or a rigid column) is used to impact the side of the vehicle to be tested at a certain speed to evaluate whether the side structure of the vehicle can maintain sufficient strength during the collision to reduce the impact on the occupants. Since the establishment of the automotive CAE model, submission of routine tasks, extraction of results, and statistics of data in each analysis process are all cumbersome and time-consuming tasks, seriously affecting the project development progress.

[0028] Therefore, the embodiments of the present application provide an automobile collision analysis system, method, device and medium. The technical solution of the present application will be described in detail below with reference to specific embodiments.

[0029] Please refer to Figure 1 , Figure 1 which is a schematic architecture diagram of an automobile collision analysis system in an embodiment of the present application. The automobile collision analysis system provided by the embodiments of the present application includes: an interaction interface 01, configured to obtain a target configuration of information to be submitted by a vehicle simulation model after a vehicle collision in response to an interaction operation; a collision analysis module 02, configured to obtain corresponding information to be submitted according to the target configuration and convert it into data to be analyzed, and call a preset analysis tool to solve the data to be analyzed, and extract target data associated with collision indicators from the solution results; a report generation module 03, configured to call a matching report template according to the data to be analyzed, the solution results and the target data to generate an analysis report. The user can input information through the interaction interface 01. The input information may include a vehicle simulation model to be used, a code file for solving the data to be analyzed, a code file for extracting data from the solution results, etc. The vehicle simulation model may include setting information, material information, a body model, a tire model, link information, etc. Exemplarily, the interaction interface 01 can display selectable simulation model files and their sources. When the user selects a model header file or main file to be used, the interaction interface 01 can link to the folder storing the header file or main file, and then display a list of selectable files, and configure the model according to the displayed file list to meet the current simulation requirements. The interaction interface 01 can be a display interface of a portable terminal (such as a mobile phone, a tablet, etc.) or a touch interface integrated on a specific device, and can be specifically set and adjusted according to actual needs, which is not limited here.

[0030] In one embodiment, the interaction interface 01 can also obtain a matching file from a target terminal according to the input information and generate a list of selectable files. Exemplarily, the user can input a piece of text (such as a description text of collision requirements, etc.) in the interaction interface 01; the interaction interface 01 sends the input information to the server side or uses a local processor to perform text recognition, and extracts feature information from the text, and based on the feature information, obtains matching files from the server side or locally, such as vehicle simulation model files, configuration files and other associated data files, and generates a file list according to the relevance of the matching files for the user to select and apply. Of course, after receiving the text information of the interaction interface 01, the server side can use relevant text recognition models for recognition, or use a knowledge graph to associate various files for matching and calling. The specific recognition tool can be set and selected according to actual application requirements, which is not limited here.

[0031] In one embodiment, various vehicle simulation models can also be pre-stored in a specified file path. When setting the vehicle simulation model through the interaction interface 01, the vehicle simulation model to be used for collision analysis can be determined by selecting the file path. The corresponding vehicle simulation model can be selected according to the actual collision requirements for collision simulation. The collision analysis here can be a vehicle side collision analysis or other types of collision analysis, which can be determined according to the project requirements and are not limited here.

[0032] In one embodiment, various configuration information in the entire collision automated analysis process can be input through the interaction interface 01, such as the information to be submitted by the vehicle simulation model after completing the collision simulation, the model configuration to be used, the vehicle simulation model parameter configuration, the operating environment configuration, etc. The model configuration can include configuration module information, file type information, file list requirements, control information, calculation time information, etc.

[0033] In one embodiment, the collision analysis module 02 further includes: a model update module for updating the model parameters according to the target configuration so that the updated vehicle simulation model outputs the corresponding information to be submitted after completing the collision simulation; a solver for receiving the solution code corresponding to the preset analysis tool to solve the data to be analyzed based on the solution code and obtain the solution result; a data extraction module for obtaining the extraction code according to the target configuration information and passing it to the corresponding data extraction tool to identify the data associated with the collision index in the solution result as the target data. Exemplarily, the target configuration may include the parsing code corresponding to the vehicle simulation model required for collision analysis, and parameters such as the format or type of the data required by the solver during analysis. The model is parsed using the parsing code to facilitate the extraction of more targeted data from the information submitted by the model for analysis, reduce interference data, and improve the analysis and processing efficiency. The solver can integrate the LSDYNA software, and use LSDYNA as one of the preset analysis tools to solve the information submitted by the model to obtain the solution result. Before solving, if the information submitted by the model does not meet the corresponding type or parameter requirements, the submitted information can be converted into the data to be analyzed that meets the requirements and then passed to LSDYNA for solving. The specific solving method can be adjusted according to the data of different collision analyses and is not limited here. During the information conversion process, the LSDYNA analysis configuration information can be parsed from the target configuration obtained from the interaction interface 01, so that the solver can automatically obtain the model information in LSDYNA for solving. The data extraction module can integrate the META software, and use META to extract the key information associated with the collision index in the solution result as the target data. Information such as the target data and the solution result can be saved to a specific file for subsequent query and use.

[0034] In one embodiment, the model update module includes a parsing unit for parsing a code file according to a target configuration link model and passing the model parsing code file to a corresponding vehicle simulation model to parse the vehicle simulation model to obtain sub-models corresponding to different collision indicators; a model update unit for updating the sub-models according to the model parameters in the target configuration so that each sub-model completes a collision simulation based on the updated parameters. Exemplarily, the model parsing code file can be pre-saved in a specified file path. During the configuration process through the interactive interface 01, the required model parsing code file can be called from the corresponding file path and passed to the parsing unit, so that the parsing unit parses the vehicle simulation model to be used according to the model parsing code file, disassembling the model into multiple sub-models, and each sub-model corresponds to a different collision indicator. The collision indicators and the model parsing code file here can be set and adjusted according to the actual model and collision analysis requirements, and are not limited here. After completing the model parsing, update the model parameters configured in the interactive interface 01 to the corresponding sub-models, and use the updated vehicle simulation model to perform a collision simulation. Of course, the model parsing code can also only parse the architecture, parameters, etc. of the vehicle simulation model to be used, so as to correspond the configuration of the interactive interface 01 with the parsed parameters, so as to perform parameter replacement and update based on the configuration.

[0035] In one embodiment, the solver is further configured to obtain a solution code file according to the target configuration and pass the solution code file to a corresponding preset analysis tool, so that the preset analysis tool automatically completes the solution based on the information submitted by the updated sub-models and obtains a solution result. Before the vehicle simulation model submits information, the submission code file can be obtained by parsing the target configuration and passed to each LSDYNA software, so that the LSDYNA software calls the corresponding model in the software based on the code file to perform a solution calculation and obtain a solution result.

[0036] In one embodiment, the data extraction module is further configured to obtain a data extraction code file according to the target configuration and pass the data extraction code file to a corresponding data extraction tool, so that the data extraction tool extracts data based on the solution result to obtain target data. Specifically, the data extraction code file specified by the interactive interface 01 can be obtained by parsing the target configuration, and the data extraction code file is passed to the META software, and then the relevant data extraction tools in the META software are called to extract data. The data type, characteristics, etc. of the target data to be extracted can be specified in the data code file, so that the software can identify the associated data in the solution result based on the corresponding type or characteristics and obtain the required target data to automatically complete data collation.

[0037] In one embodiment, before generating a report, the report generation module 03 can automatically generate a collision analysis report according to the report requirement information (report file type, format, etc.) configured in the aforementioned interaction interface 01. Further, a code file for generating a report in a specific form can be specified in the interaction interface 01. After obtaining the data required for generating the report, the corresponding code file can be called to automatically generate a collision analysis report that meets the format requirements. The analysis report can be in the form of a PPT or a text, and can be specifically set and adjusted according to actual requirements, which is not limited here.

[0038] In one embodiment, the system may further include a data feedback module for feeding back the data to be analyzed, the solution results, and the target data to the target storage path. After operations such as solution, data extraction, and report generation are completed, various types of data can be fed back to the specified storage path through the data feedback module. The storage path can be in the cloud or a local path, and can be flexibly configured according to requirements.

[0039] In one embodiment, the aforementioned code files for generating reports, data extraction, and model submission information can all be pre-written and stored in a specific file path for easy configuration and invocation through the interaction interface 01.

[0040] Based on the technical solutions of the embodiments of the present application above, systematic management of the collision calculation model and calculation results can be achieved, facilitating subsequent query and optimization; the workload of model submission by engineers can be effectively reduced, and the time for viewing model results can be shortened; key data for collision analysis can be directly obtained, reducing the workload of manual collation, and thus effectively shortening the project R & D time.
