[0062] As mentioned earlier, physical object modeling scenarios demand a high level of user skill and involve complex operations, resulting in low simulation modeling efficiency and a poor user experience. Specifically, GCKontrol software lacks the ability to model physical objects; users must first gain a thorough understanding of the physical object to be modeled before manually building the corresponding simulation model, and only then can simulation testing be conducted.
[0063] To address the aforementioned problems, this application provides a method for modeling a physical object, comprising: responding to a user-submitted modeling request, obtaining the physical object to be modeled, and first determining the working principle of the physical object. Then, based on the working principle, generating a bond graph for the physical object, and based on the bond graph, generating a signal flow graph of the physical object. In this way, a simulation model of the physical object can be constructed using the bond graph and the signal flow graph.
[0064] It is evident that by clearly defining the working principle of the physical object, a unified physical law can be provided to support subsequent modeling, ensuring that the model conforms to the objective physical essence and improving the accuracy of modeling. In this way, subsequent generation of bond graphs, signal flow graphs, and ultimately simulation models of the physical object can be achieved based on the working principle, without requiring manual construction by the user. This helps reduce user operational complexity and improves simulation modeling efficiency.
[0065] Furthermore, bond graphs can be used to transform abstract physical laws into standardized graphical representations, enabling a unified framework for multi-physics domain modeling; signal flow graphs can be used to transform physical essence descriptions into platform-recognizable causal relationship expressions, improving the compatibility between physical essence and platform implementation.
[0066] It should be noted that the embodiments of this application do not limit the executing entity of the physical object modeling method. For example, the physical object modeling method of this application embodiment can be applied to data processing devices such as servers or terminal devices. The server can be a standalone server, a cluster server, or a cloud server. The terminal device can be an electronic device such as a smartphone, computer, personal digital assistant (PDA), or tablet computer.
[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0068] Figure 1 This is a flowchart illustrating a method for modeling a physical object as provided in an embodiment of this application. (In conjunction with...) Figure 1 As shown, the physical object modeling method provided in this application embodiment may include the following steps S101-S105.
[0069] S101: In response to a user-submitted modeling request, obtain the physical object to be modeled.
[0070] Here, a modeling request refers to a user-initiated instruction that explicitly requests the construction of a model of a specific physical object. In practical applications, users can issue this instruction through the GCKontrol software.
[0071] The physical object to be modeled is the physical object that the user expects to simulate and test through modeling. For example, in the field of mechanics, rotating inertia elements or spring dampers; in the field of electrical engineering, capacitors or resistors; and in the field of hydraulics, cylinders or relief valves are all physical objects to be modeled.
[0072] Accordingly, in practical applications, the modeling request submitted by the user can be read directly to determine the physical parameters.
[0073] S102: Determine the working principle of the physical object.
[0074] Here, the working principle of a physical object refers to the core physical laws, energy conversion mechanisms, and variable correlation logic that the physical object follows in its actual operation. It is the essential basis for the physical object to realize its function. That is, the working principle can explain which physical quantities (such as force, torque, or voltage) will act on the physical object, what physical laws (such as the laws of mechanics, electromagnetic laws, or the law of conservation of energy) the physical object uses to transform input into output, and what kind of motion state or physical effect it ultimately exhibits.
[0075] For example, if the physical object is a rotating inertia element, its working principle is that the net external torque is proportional to the angular acceleration; that is, the input torque is converted into a change in angular velocity through the inertial effect of the rotational inertia. If the physical object is a capacitor element, its working principle is based on the correlation between charge storage and voltage; that is, the input voltage is converted into charge accumulation through the charge storage effect of the capacitor, which in turn affects the change in current. If the physical object is a spring damper, its working principle is the superposition of Hooke's law and the damping law; that is, the input displacement or velocity is converted into output elastic force or damping force through elastic deformation and damping dissipation.
[0076] Accordingly, in this embodiment, standard working principle information of common physical objects in different physical domains such as mechanics, electricity, hydraulics, or thermodynamics can be pre-written and stored using GCKontrol software. Then, based on the physical objects identified above, precise matching is performed in the stored information to obtain the corresponding working principle.
[0077] S103: Based on the working principle, generate a bond graph for the physical object.
[0078] Bond graphs are graphical modeling tools that uniformly describe the energy flow and transformation laws of multi-physics domain systems. They use a set of standardized graphical symbols to transform the working principles of physical objects into intuitive and unambiguous graphical representations, without relying on the technical terms of specific physical domains, thus achieving unified modeling of cross-domain physical systems.
[0079] Accordingly, in the embodiments of this application, firstly, based on the working principle, the basic components that match the working principle can be determined. For example, based on the working principle, it can be determined whether the basic components corresponding to the physical object belong to the type of kinetic energy storage, potential energy storage, energy consumption, or energy conversion.
[0080] Next, the power bonds of the basic components are determined. These power bonds include potential variables and current variables. For example, in the working principle of a moment of inertia element, torque is a potential variable and angular velocity is a current variable; while in the working principle of a resistor, voltage is a potential variable and current is a current variable.
[0081] In this way, topological connections can be made based on basic components and power bonds to generate a bond graph.
[0082] S104: Generate the signal flow graph of the physical object based on the bond graph.
[0083] A signal flow graph is a graphical modeling tool that uses directed graphs to describe the causal relationships between variables in a system. It can associate the energy flow of physical objects with variables and transform it into a clear logical chain from input signals to processing modules to output signals.
[0084] Accordingly, in the embodiments of this application, firstly, the causal relationship between potential variables and current variables can be determined based on the bond graph. This causal relationship is used to indicate the input and output variables in the signal flow graph. For example, the causal relationship between the potential and current variables of a moment of inertia element is: the input variable is torque, and the output variable is angular velocity change; the causal relationship between the potential and current variables of a resistive element is: the input variable is voltage, and the output quantity is current (current variable). Furthermore, in practical applications, the direction between input and output variables is that the input variable points to the output variable. Generally speaking, the input variable is located on the left side of the model, and the output variable is located on the right side of the model.
[0085] Furthermore, a signal flow graph can be generated based on the basic components, input variables, and output variables. Here, the signal flow tool in GCKontrol software can be used to transform the abstract basic components used to generate the bond graph into graphical modules. For example, a rotational inertia component can be transformed into an integral module in the signal flow. Then, a signal flow graph is generated based on the transformed graphical modules, input variables, and output variables.
[0086] S105: Construct a simulation model of the physical object using bond graphs and signal flow graphs.
[0087] In this embodiment, the bond graph and signal flow graph can be integrated based on the working principle to obtain a simulation model. Specifically, the working principle of the physical object can be used as a unified constraint to associate parameters and logically bind the bond graph and signal flow graph to generate a simulation model.
[0088] Furthermore, in this embodiment, the simulation model of the physical object can also be simulated and solved using an Ordinary Differential Equation (ODE) solver in the GCKontrol software, and the simulation results can be obtained and output. Since the bond graph can provide the physical essence of the simulation model and the signal flow graph can realize the platform operability of the model, the simulation model constructed by combining the two has a reliable physical foundation and can be directly compiled and run on the GCKontrol software.
[0089] Specifically, the GCKontrol software includes a simulation model of the control system. Accordingly, during the simulation process, a connection can be established between the simulation model of the physical object and the simulation model of the control system. Based on this connection, control commands can be sent from the simulation model of the control system to the simulation model of the physical object, and the simulation model of the physical object can respond to these control commands to perform the simulation.
[0090] Next, the simulation process of the physical object's simulation model is solved using the ODE solver to obtain the simulation results. Since the state changes of a physical object (such as velocity, temperature, or pressure) often follow the laws of ordinary differential equations, the ODE solver can accurately solve these equations using numerical calculation methods to obtain the state changes of the physical object under different times and control commands, i.e., the simulation results.
[0091] As can be seen, since the final simulation model is consistent with the control system model in the GCKontrol software, it can achieve seamless integration between the physical object model and the control system model and provide real-time simulation functionality.
[0092] Based on the relevant content of steps S101-S105 above, it can be seen that in this embodiment, after obtaining the physical object to be modeled in response to the user's submitted modeling request, the working principle of the physical object can be determined first. Then, based on the working principle, a bond graph is generated for the physical object, and based on the bond graph, a signal flow graph of the physical object is generated. In this way, a simulation model of the physical object can be constructed using the bond graph and the signal flow graph. It is evident that by clarifying the working principle of the physical object, a unified physical law can be provided to support subsequent modeling, ensuring that the model conforms to the objective physical essence and improving the accuracy of modeling. Thus, the subsequent generation of the bond graph and signal flow graph based on the working principle, and subsequently the generation of the simulation model of the physical object, does not require manual construction by the user, helping to reduce the complexity of user operations and improve the efficiency of simulation modeling.
[0093] Based on the physical object modeling method provided in the above embodiments, this application embodiment can also provide an application example of the physical object modeling method. The application example of the physical object modeling method will be described below with reference to the embodiments and accompanying drawings.
[0094] Figure 2 This diagram illustrates an application example of a physical object modeling method provided in this embodiment. The physical object is taken as an example of a rotating inertia element, combined with... Figure 2 As shown, in the left bond graph, the input torque is a potential variable, while in the right bond graph, the output speed is a flow variable.
[0095] The signal flow graph in the middle describes the calculation logic of physical quantities, corresponding to the formula of rotational dynamics. That is, the summation module T summarizes the input torque, the division module accel divides the torque by the torque by the moment of inertia to obtain the angular acceleration (accel), and the integration module (1 / s) integrates the angular acceleration to obtain the speed output.
[0096] As can be seen, this modeling approach allows for the definition of energy domain physical quantities for input (torque) and output (rotational speed) using the bond graph, and the description of the mathematical transformation process from torque to angular acceleration and then to rotational speed using the signal flow graph. In this way, the combination of bond graphs and signal flow graphs intuitively expresses the working principle of the physical object, constructing a simulation model of the physical object without requiring manual user setup, thus reducing user complexity and improving simulation modeling efficiency.
