[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. The present application provides a method, device, equipment and storage medium based on joint simulation, which are used in the field of simulation analysis technology. The above is only an example and does not limit the application field of the method and device name provided by the present application.

[0051] The three-dimensional thermal simulation analysis software TAITherm can fully simulate heat conduction, heat convection and heat radiation problems. With its professional model library and material library, convenient thermal modeling method and good thermal solution ability, it is widely used in thermal simulation, thermal protection design, thermal feature simulation, etc. in the automotive, industrial automation, rail transportation, heavy machinery and other industries. The CoTherm coupling optimization platform of the same series can support applications such as thermal flow coupling, one-three-dimensional coupling, FMU integration, design optimization, sensitivity analysis, etc. The CoTherm software provides automatic coupling functions between TAITherm and various tools such as Start-CCM+, Fluent, OpenFoam, GT, Simulink, etc., and supports FMU integrated coupling simulation, making the method of using thermal flow coupling to simulate long-term instantaneous heating processes more efficient.

[0052] At present, when using the three-dimensional thermal simulation analysis software TAITherm for multi-disciplinary joint simulation in China, the technology provided by CoTherm software is adopted to realize the integrated solution of multiple models such as one-dimensional thermal simulation and heat exchange, such as joint optimization of thermal system and control algorithm, driving cycle thermal comfort simulation and thermal management system optimization.

[0053] In the existing TAITherm-based simulation process, if you want to achieve joint simulation, you need to use the supporting Cotherm software to achieve simulation interaction with a specific model. For other models other than the third-party simulation tools supported by the CoTherm software, joint simulation of the model cannot be achieved.

[0054] Taking the engine thermal simulation as an example, the engine is composed of the following components: crank-connecting rod structure: composed of the main body group, piston-connecting rod group, crankshaft flywheel group; valve mechanism: composed of valve group and valve transmission group; cooling system: composed of water pump, radiator, fan, thermostat, coolant; lubrication system: composed of oil pump, oil filter, oil filter element, oil radiator and medium lubricating oil; ignition system: composed of battery, generator, ignition coil, spark plug, ignition switch; starting system: composed of battery, starter and ignition switch; fuel supply system: composed of fuel tank, gasoline pump, air filter, intake manifold, high-pressure oil pump, fuel injector, sensor, electronic control unit.

[0055] The integrated thermal management of the engine is to manage the heat of the whole machine in a unified way to achieve the rational use of energy. Each system of the engine needs to use different simulation tools to build models to achieve thermal simulation of the whole machine, involving multiple types and dimensions of simulation tools, including third-party simulation tools that CoTherm does not support, so joint simulation cannot be achieved.

[0056] After research, the inventor proposed the technical solution of the present application. When executing the method, the user interface library provided by the three-dimensional thermal simulation analysis software is first called to obtain the processing program for the model parameters in different model control stages, and the processing program is encapsulated into an interface function. Then, a first dynamic link library is constructed using the interface function, and the first dynamic link library is imported into the three-dimensional thermal simulation analysis software. Then, a second dynamic link library is constructed based on the user interface library, wherein the second dynamic link library is used to parse the model parameters. Then, a first simulation model is constructed in the three-dimensional thermal simulation analysis software, and a second simulation model is constructed in the target simulation software. The model parameters of the first simulation model are parsed using the second dynamic link library to obtain the input variables and output variables of the first simulation model. The input variables and output variables of the first simulation model are bound to the input variables and output variables of the second simulation model to obtain the first simulation model and the second simulation model after the input and output variable relationship is bound. Finally, the interface function in the first dynamic link library is used to jointly simulate the first simulation model and the second simulation model after the input and output variable relationship is bound. That is, according to the user interface library provided by the three-dimensional thermal simulation analysis software, a first dynamic link library for processing model parameters in different model control stages and a second dynamic link library for parsing model parameters are constructed. The model parameters of the first simulation model are first parsed using the second dynamic link library to obtain the input and output variables of the first simulation model, and the input and output variables of the first simulation model are bound to the input and output variables of the second simulation model. Finally, the joint simulation of the first simulation model and the second simulation model can be realized by calling the interface function in the first dynamic link library. In this way, the joint simulation of the three-dimensional thermal simulation analysis software and different simulation tools can be realized.

[0058] See also Figure 1 , Figure 1 A flowchart of a joint simulation method provided in an embodiment of the present application includes:

[0059] S101: calling the user interface library provided by the three-dimensional thermal simulation analysis software TAITherm to obtain the processing procedures for the model parameters in different model control stages.

[0060] The 3D thermal simulation analysis software TAITherm provides a user interface library, which is a library that provides interaction between users and software. The programs in the user interface library can realize the acquisition and configuration of model parameters. You can use C++, Paython and other languages ​​to call the user interface library provided by TAITherm to obtain the processing program for model parameters in different model control stages, where the model control stage includes model loading, model starting, model running and model stopping.

[0061] S102: Encapsulate the processing program into an interface function.

[0062] First determine the function of each handler, and then encapsulate the handlers into different interface functions according to different functions. For example: the function of the handler is to initialize and configure the model's variables when the model is loaded, then encapsulate the handler into an initialization configuration interface function, and the initialization configuration interface function is used to call the model when the model is loaded during the model control phase; the function of the handler is to obtain the initial input variables and allocate memory resources when the model starts, then encapsulate the handler into an initial input variable acquisition interface function, and the initial input variable acquisition interface function is used to call the model when the model starts during the model control phase; the function of the handler is to call once at the beginning of each model step when the model is running to obtain the input variables, then encapsulate the handler into a first input variable acquisition interface function, and the first input variable acquisition interface function is called when the model is running during the model control phase; the function of the handler is to call a fixed number of times at each model step when the model is running, and the fixed number can be set according to the actual situation to obtain the input variables and configure them to the model, then encapsulate the handler into The processing program is encapsulated as a second input variable acquisition interface function, which is called when the model is running in the model control stage; the function of the processing program is to call a fixed number of times at each model step when the model is running, and the fixed number of times can be set according to actual conditions to obtain output variables for the interactive model, and the processing program is encapsulated as a first output variable acquisition interface function, which is called when the model is running; the function of the processing program is to call once at the end of each model step when the model is running to obtain output variables for the interactive model, and the processing program is encapsulated as a second output variable acquisition interface function, which is called when the model is running; the function of the processing program is to obtain the final solution result and release memory resources when the model stops, and the processing program is encapsulated as a final solution interface function, which is called when the model stops in the model control stage.

[0063] S103: constructing a first dynamic link library using the interface function, and importing the first dynamic link library into the three-dimensional thermal simulation analysis software.

[0064] The multiple interface functions encapsulated in S102 are constructed into a first dynamic link library, and the first dynamic link library includes multiple interface functions, for example, the first dynamic link library includes: an initialization configuration interface function, an initial input variable acquisition interface function, a first input variable acquisition interface function, a second input variable acquisition interface function, a first output variable acquisition interface function, a second output variable acquisition interface function, and a final solution interface function. After the first dynamic link library is constructed, the first dynamic link library is imported into the three-dimensional thermal simulation analysis software TAITherm, so that the interface function in the first dynamic link library can be called through the TAITherm software during the simulation process.

[0065] S104: Building a second dynamic link library based on the user interface library.

[0066] The three-dimensional thermal simulation analysis software TAITherm provides a TDFIO interface library, which provides functions including creating, reading, querying, modifying and writing TAITherm TDF files, and by calling the TDFIO interface library, the model parameters of the TAITherm model constructed by the three-dimensional thermal simulation analysis software TAITherm can be changed. In some embodiments, the TDFIO interface library can be called using a C++ language program, and the C++ language program can be encapsulated as a second dynamic link library for external calls. The second dynamic link library can be used to parse the model parameters of the TAITherm model.

[0067] S105: Constructing a first simulation model in three-dimensional thermal simulation analysis software.

[0068] Open the three-dimensional thermal simulation analysis software TAITherm, and construct a TAITherm model in the three-dimensional thermal simulation analysis software TAITherm as the first simulation model.

[0069] S106: Constructing a second simulation model in the target simulation software.

[0070] Open the target simulation software, and construct a second simulation model in the target simulation software. For example, open the visualization simulation software Simulink, and construct a Simulink model in Simulink as the second simulation model.

[0071] S107: Utilize the second dynamic link library to parse the model parameters of the first simulation model to obtain input variables and output variables of the first simulation model.

[0072] The second dynamic link library is called to parse the model parameters of the first simulation model to obtain a parsing result, wherein the parsing structure includes input variables and output variables of the first simulation model.

[0073] S108: Binding the input variables and output variables of the first simulation model with the input variables and output variables of the second simulation model to obtain the first simulation model and the second simulation model after binding the input and output variable relationship.

[0074] Before the joint simulation begins, the input variables and output variables of the first simulation model need to be bound to the input variables and output variables of the second simulation model to obtain the first simulation model and the second simulation model after the input and output variable relationship is bound. In some embodiments, the input and output variable table can be generated by calling the second dynamic link library, and the input variables and output variables of the first simulation model and the input variables and output variables of the second simulation model are filled into the input and output variable table to achieve the input and output variable binding of the first simulation model and the second simulation model.

[0075] S109: Using the interface function in the first dynamic link library, jointly simulating the first simulation model and the second simulation model after binding the input and output variable relationship

[0076] Before executing step S109, it is necessary to first determine the simulation steps of the first simulation model in different model control stages, and set the association relationship between the interface corresponding to the interface function in the first dynamic link library and the simulation step, so as to call the corresponding interface function during the simulation process of the model. For example, when the model control stage is model loading, the simulation step needs to initialize the variables, and then it is necessary to call the initialization configuration interface function to implement the initialization configuration of the variables.

[0077] The joint simulation process of the first simulation model and the second simulation model after binding the input-output variable relationship is performed as follows: the model control stage of the first simulation model includes: model loading, model starting, model running and model stopping, and the interface function in the corresponding first dynamic link library is executed in different model control stages to realize the joint simulation of the first simulation model and the second simulation model after binding the input-output variable relationship. For example, when the model control stage is model loading, the initialization configuration interface function is called to initialize the configuration of the model variables; when the model control stage is model start, the initial input variable acquisition interface function is called to acquire the initial input variables and allocate memory resources; when the model control stage is model operation, the first input variable acquisition interface function can be called once at the beginning of each model step to acquire the input variables; when the model control stage is model operation, the second input variable acquisition interface function can be called a fixed number of times in each model step, and the fixed number can be set according to actual conditions to acquire the input variables and configure them to the first simulation model; when the model control stage is model operation, the first output variable acquisition interface function can be called a fixed number of times in each model step, and the fixed number can be set according to actual conditions to acquire the output variables for interaction with the second simulation model; when the model control stage is model operation, the second output variable acquisition interface function can be called once at the end of each model step to acquire the output variables for the interactive model; when the model control stage is model end, the final solution interface function is called to acquire the final solution result and release memory resources.

[0078] In some implementations, after obtaining the final solution result, that is, completing the joint simulation, the simulation result can be displayed, and the specific display form is not limited here.

[0079] In an embodiment of the present application, a user interface library provided by the three-dimensional thermal simulation analysis software is first called to obtain a processing program for model parameters in different model control stages, and the processing program is encapsulated into an interface function. Then, a first dynamic link library is constructed using the interface function, and the first dynamic link library is imported into the three-dimensional thermal simulation analysis software. Then, a second dynamic link library is constructed based on the user interface library, wherein the second dynamic link library is used to parse the model parameters. Then, a first simulation model is constructed in the three-dimensional thermal simulation analysis software, and a second simulation model is constructed in the target simulation software. The model parameters of the first simulation model are parsed using the second dynamic link library to obtain input variables and output variables of the first simulation model. The input variables and output variables of the first simulation model are bound to the input variables and output variables of the second simulation model to obtain the first simulation model and the second simulation model after the input and output variable relationship is bound. Finally, the interface function in the first dynamic link library is used to jointly simulate the first simulation model and the second simulation model after the input and output variable relationship is bound. That is, according to the user interface library provided by the three-dimensional thermal simulation analysis software, a first dynamic link library for processing model parameters in different model control stages and a second dynamic link library for parsing model parameters are constructed. The model parameters of the first simulation model are first parsed using the second dynamic link library to obtain the input and output variables of the first simulation model, and the input and output variables of the first simulation model are bound to the input and output variables of the second simulation model. Finally, the joint simulation of the first simulation model and the second simulation model can be realized by calling the interface function in the first dynamic link library. In this way, the joint simulation of the three-dimensional thermal simulation analysis software and different simulation tools can be realized.
