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

[0061] The simulation solving method of an aero-engine provided by the embodiment of the present application can be applied to the application environment of aero-engine multi-system joint simulation. The method can be applied to a terminal, a server, or a system including a terminal and a server, and is realized through the interaction of the terminal and the server. The terminal can be, but is not limited to, various personal computers, notebook computers, medium-sized computers, etc. The terminal identifies the simulation interaction information between the structure systems after simulating and modeling each structure system by using the system running function information, the system structure data, and the system association information of each structure system, and finally constructs a joint simulation model of the aero-engine capable of simulating and interacting data jointly based on the simulation interaction information. The joint simulation model not only avoids the problem of large simulation deviation of single system modeling, but also can identify the simulation running data and the simulation running result of each system when the aero-engine is running, thereby improving the simulation accuracy of the aero-engine. Finally, the joint simulation result of the aero-engine is distributedly solved and jointly progressively solved by using the constructed joint simulation solving algorithm in the actual simulation process, which avoids the problem of significantly increased solving difficulty and long solving time and difficulty in convergence caused by the large number of solving equations after unified modeling, thereby improving the simulation accuracy, efficiency, and convergence robustness of the aero-engine.

[0062] In an exemplary embodiment, as shown in Figure 1 A simulation solving method of an aero-engine is provided. The method is applied to a terminal as an example, and includes the following steps S101 to S104. Wherein:

[0063] In step S101, system operation function information of each structural system of the aero-engine, system structure data of each structural system, and system association information between the structural systems are acquired, and based on the system operation function information of each structural system and the system structure data of each structural system, a sub-simulation operation model of each structural system is constructed.

[0064] In this embodiment, the terminal acquires, in response to an information uploading operation of the staff, the system operation function information of each structural system of the aero-engine, the system structure data of each structural system, and the system association information between the structural systems. The system structure of each system is a device structure that constitutes the aero-engine. The system structure includes an air intake system, a compression system, a combustion chamber system, a turbine system, an exhaust system, and a fuel supply system. The system operation function information includes system functions of each system structure and system operation information of each system structure, and the system structure data is system three-dimensional structure data of each system structure, which can be obtained by the staff performing three-dimensional scanning on each system structure. The system association information between each system structure includes association information of each association type. The association type is used to represent data interaction association and operation interaction association between two system structures. The association type includes but is not limited to a data transmission direction type, a data format conversion type, a data transmission restriction type, an operation function interaction type, an operation mode interaction type, and an operation flow interaction type. The association type belonging to the data interaction type includes but is not limited to the data transmission direction type, the data format conversion type, and the data transmission restriction type, and the association type belonging to the operation interaction type includes but is not limited to the operation function interaction type, the operation mode interaction type, and the operation flow interaction type. The specific identification will be described in detail later. Finally, the terminal constructs a sub-simulation operation model of each structural system based on the system operation function information of each structural system and the system structure data of each structural system. Each sub-simulation operation model can simulate the operation process of the structural system.

[0065] In step S102, based on the system association information between the structural systems, data interaction association information between the structural systems and operation interaction association information between the structural systems are identified, and based on the data interaction association information between the structural systems and the operation interaction association information between the structural systems, simulation interaction information between the structural systems is constructed.

[0066] In this embodiment, the terminal identifies the data interaction association information between the structural systems and the operation interaction association information between the structural systems based on the system association information between the structural systems, and constructs the simulation interaction information between the structural systems based on the data interaction association information between the structural systems and the operation interaction association information between the structural systems. The data interaction association information includes the data interaction information between the structural systems and the data transmission information between the structural systems, and the operation interaction association information includes the operation interaction mode between the structural systems and the operation interaction process between the structural systems. The specific identification process will be described in detail later. The constructed simulation interaction information between the systems is the simulation operation interaction process between the structural systems and the simulation data interaction process between the structural systems. The specific construction process will be described in detail later.

[0067] In step S103, based on the simulation interaction information between the structural systems, the terminal performs simulation association processing on the structural systems to obtain a joint simulation model of the aero-engine, and collects the demand input data of the aero-engine.

[0068] In this embodiment, the terminal performs simulation association processing on the structural systems based on the simulation interaction information between the structural systems to obtain a joint simulation model of the aero-engine, and collects the demand input data of the aero-engine. The simulation association processing process is to associate the simulation operation processes of the structural systems to ensure that the joint simulation process between the structural systems can be realized in the simulation operation process. The specific association processing process will be described in detail later. Then, the terminal collects the demand input data of the aero-engine, which is the data information corresponding to the simulated operation condition, the simulated operation mode, and the simulated operation process of the aero-engine required by the staff. The data information is the data information uploaded to the terminal by the staff, which can be changed according to the adjustment of the staff.

[0069] In step S104, based on the demand input data, the terminal generates a joint simulation result of the aero-engine through the joint simulation model of the aero-engine, and identifies the operation solving data of the aero-engine through a joint simulation solving algorithm based on the joint simulation result.

[0070] In this embodiment, the terminal generates a joint simulation result of the aero-engine through the joint simulation model of the aero-engine based on the demand input data, and identifies the operation solving data of the aero-engine through a joint simulation solving algorithm based on the joint simulation result. The joint simulation solving algorithm includes the system simulation solving algorithm of each structural system and the system association solving algorithm between each structural system, and the solving mode of the system association solving algorithm and the solving mode of the system simulation solving algorithm will be described in detail later.

[0071] Based on the above scheme, by simulating and modeling each structural system respectively from the system operation function information, system structure data and system association information of each structural system, identifying the simulation interaction information between each structural system, and finally, based on the simulation interaction information, constructing a joint simulation model of the aero-engine which can simulate and interact data respectively, not only avoids the problem of large simulation deviation of single system modeling, but also through the joint simulation model, when the aero-engine operation simulation is carried out, the simulation running data and simulation running result of each system can be identified respectively, thereby improving the simulation accuracy of the aero-engine. Finally, in the actual simulation process, the joint simulation result of the aero-engine is distributed and solved by the joint simulation solving algorithm constructed in the scheme, and is solved by joint progressive solving, which avoids the problem that the solving equation increases greatly after unified modeling, which causes the solving difficulty to increase significantly and is difficult to converge, thereby improving the simulation accuracy of the aero-engine while effectively improving the simulation efficiency and simulation convergence robustness of the aero-engine.

[0072] Optionally, based on the system operation function information of each structural system and the system structure data of each structural system, a sub-simulation running model of each structural system is constructed, including: based on the system structure data of each structural system, constructing a system structure model of each structural system through a three-dimensional modeling program, and for each structural system, based on the system operation function information of the structural system, identifying the structural running data of each running function type; based on the structural running data of each running function type, converting the structural running data of each running function type into the structural running data of each running function type through a data parameter conversion program, and adjusting the system structure model of the structural system based on the structural running data of each running function type to obtain a sub-simulation running model of the structural system.

[0073] In this embodiment, the terminal constructs a system structure model of each structural system based on the system structure data of each structural system through a three-dimensional modeling program, and for each structural system, identifies structural operation data of each operation function type based on system operation function information of the structural system. The three-dimensional modeling program is a structural modeling method based on modeling languages such as Modelica, C / C++, Fortran, and Python. Then, the terminal converts the structural operation data of each operation function type into structural operation parameters of each operation function type based on the structural operation data of each operation function type through a data parameter conversion program, and adjusts the system structure model of the structural system based on the structural operation parameters of each operation function type to obtain a sub-simulation operation model of the structural system. The data parameter conversion program stores data conversion instructions between the structural operation data of different operation function types and the structural operation parameters, and then the terminal generates the structural operation parameters of each operation function type through the data conversion instructions of each operation function type. Each operation function type is a function type corresponding to each operation function included in each structural system. For example, the operation functions of the fuel supply system include fuel supply function, fuel adjustment function, and fuel protection function, and the operation function types of the fuel supply system include fuel supply function type, fuel adjustment function type, and fuel protection function type.

[0074] Based on the above scheme, the three-dimensional structure modeling is performed on each structural system, and the structural operation data of each structural system is split and converted to generate a sub-simulation operation model of each structural system, thereby improving the operation practicality and simulation accuracy of the constructed sub-simulation operation model.

[0075] Optionally, based on the system association information between the structural systems, the data interaction association information between the structural systems and the operation interaction association information between the structural systems are identified, including: based on the system association information between the structural systems, identifying association information of each association type between the structural systems, and querying an interaction type to which each association type belongs in an association database; based on the association information of each association type corresponding to the data interaction type, identifying data interaction information between the structural systems and data transmission information between the structural systems, and taking the data interaction information between the structural systems and the data transmission information between the structural systems as the data interaction association information between the structural systems; based on the association information of each association type corresponding to the operation interaction type, identifying an operation interaction mode between the structural systems and an operation interaction process between the structural systems, and taking the operation interaction mode between the structural systems and the operation interaction process between the structural systems as the operation interaction association information between the structural systems.

[0076] In this embodiment, the terminal identifies the association information of each association type between the structural systems based on the system association information between the structural systems, and queries the interaction type to which each association type belongs in the association database. The association database stores the interaction type range corresponding to the data interaction type and the interaction type range corresponding to the running interaction type. Then the terminal identifies the association type corresponding to the data interaction type and the association type corresponding to the running interaction type through range query.

[0077] Then, the terminal identifies the data interaction information between the structural systems and the data transmission information between the structural systems based on the association information of the association type corresponding to the data interaction type, and takes the data interaction information between the structural systems and the data transmission information between the structural systems as the data interaction association information between the structural systems. Each association type corresponding to the data interaction type includes the association type for data transmission and the association type for data interaction. The terminal processes the association information of the association type for data transmission to obtain the data interaction information between the structural systems, and then processes the association information of the association type for data interaction to obtain the data transmission information between the structural systems.

[0078] The terminal identifies the running interaction mode between the structural systems and the running interaction process between the structural systems based on the association information of the association type corresponding to the running interaction type, and takes the running interaction mode between the structural systems and the running interaction process between the structural systems as the running interaction association information between the structural systems. Each association type corresponding to the running interaction type includes the association type for interaction mode and the association type for interaction process. The terminal processes the association information of the association type for interaction mode to obtain the running interaction mode between the structural systems, and then processes the association information of the association type for interaction process to obtain the running interaction process between the structural systems.

[0079] Based on the above scheme, the association information is split into the association information of each association type through data query, and the association information of each association type is summarized according to the data interaction type and the running interaction type respectively to obtain the running interaction association information between the structural systems and the data interaction association information between the structural systems, which improves the comprehensiveness and accuracy of identifying the running interaction association information between the structural systems and the data interaction association information.

[0080] Optionally, based on the data interaction association information between the structure systems and the operation interaction association information between the structure systems, simulation interaction information between the structure systems is constructed, including: based on the operation interaction mode between the structure systems and the operation interaction process between the structure systems, simulation operation interaction processes between the structure systems are constructed; based on the data interaction information between the structure systems and the data transmission information between the structure systems, simulation data interaction processes between the structure systems are constructed; the simulation operation interaction processes between the structure systems and the simulation data interaction processes between the structure systems are taken as the simulation interaction information between the structure systems.

[0081] In this embodiment, the terminal constructs simulation operation interaction processes between the structure systems based on the operation interaction mode between the structure systems and the operation interaction process between the structure systems. The construction mode is to convert the operation interaction mode and the operation interaction process between the structure systems into operation processes (including operation interaction sequence, operation interaction process, operation interaction range, etc.) between the structure systems by modeling languages corresponding to languages such as Modelica, C / C++, Fortran, and Python, to obtain the simulation operation interaction processes between the structure systems.

[0082] Then, the terminal constructs simulation data interaction processes between the structure systems based on the data interaction information between the structure systems and the data transmission information between the structure systems. Then, the terminal takes the simulation operation interaction processes between the structure systems and the simulation data interaction processes between the structure systems as the simulation interaction information between the structure systems. The construction mode is to convert the data interaction information between the structure systems and the data transmission information between the structure systems into data transmission processes (including data transmission direction, data transmission limitation, data transmission format conversion and adjustment, etc.) between the structure systems by modeling languages corresponding to languages such as Modelica, C / C++, Fortran, and Python, to obtain the simulation data interaction processes between the structure systems.

[0083] Based on the above scheme, through the construction of the simulation operation interaction processes between the structure systems and the simulation data interaction processes, the actuality and accuracy of the simulation interaction between the structure systems are ensured.

[0084] Optionally, based on the simulation interaction information between the structure systems, the structure systems are simulated and associated to obtain a joint simulation model of the aero-engine, including: collecting physical connection information between the structure systems, and based on the physical connection information between the structure systems, performing model connection processing on the sub-simulation running models of the structure systems to obtain a joint three-dimensional structure model of the aero-engine; based on the simulation interaction information between the structure systems, constructing simulation interaction parameters between the structure systems in the joint three-dimensional structure model, and adjusting the simulation interaction parameters between all the structure systems to adjust the joint three-dimensional structure model to obtain the joint simulation model of the aero-engine.

[0085] In this embodiment, the terminal collects the physical connection information between the structure systems, and based on the physical connection information between the structure systems, performs model connection processing on the sub-simulation running models of the structure systems to obtain a joint three-dimensional structure model of the aero-engine. The physical connection information includes connection information such as connection points between two structure systems, connection modes of the connection points, and connection angles of the connection points.

[0086] Then, based on the simulation interaction information between the structure systems, the terminal constructs simulation interaction parameters between the structure systems in the joint three-dimensional structure model, and adjusts the simulation interaction parameters between all the structure systems to adjust the joint three-dimensional structure model to obtain the joint simulation model of the aero-engine. The terminal predefines parameter conversion strategies corresponding to the simulation data interaction process and the simulation running interaction process, thereby converting the simulation interaction processes into simulation interaction parameters, and improving the conversion efficiency of the simulation interaction parameters.

Finally, the terminal calculates the operation solving data of the aero-engine according to the system correlation solving algorithm between each structural system based on the system simulation solving data of each structural system.

In this process, on the one hand, the correctness of the whole solving simulation calculation result is ensured, because all the solving equations are satisfied; on the other hand, through the decomposition and separate solving of the equations to be solved, the effect of dimension reduction calculation is realized, which can reduce the difficulty and calculation amount of the whole solving, and improve the simulation calculation efficiency.
