Description

Technical Field

[0001] This application relates to the field of engineering simulation technology, and in particular to an integrated development system and method for magnetic levitation bearings and motors. Background Technology

[0002] Magnetic levitation bearings offer advantages such as no mechanical contact, no wear, long lifespan, low noise, and high speed. They can meet the requirements of high speed, high energy density, and low energy consumption during ultra-high-speed and critical bending operations. Currently, they are widely used in industrial manufacturing, semiconductor integrated circuits, medical and environmental protection, and energy and chemical industries, and have broad market application prospects.

[0003] Because magnetic levitation bearings may have unique requirements and challenges in different application scenarios, such as high temperature, high speed, and corrosive environments, it is necessary to consider how to adapt to different application environments and requirements, and carry out customized design and optimization adjustments, which increases the complexity of design and development. The design and development process of magnetic levitation bearings is complex, and currently, there is no established relevant theory that can be used to uniformly describe magnetic levitation bearings / permanent magnet synchronous motors. It is very difficult to establish a unified global model, and most existing simulation software is difficult to directly use for modeling multi-physical systems that include mechanical, electrical, magnetic, thermal, and control aspects. Summary of the Invention

[0004] Therefore, it is necessary to provide an integrated development system and method for magnetic levitation bearings and motors to address the technical problem of the difficulty in directly using existing simulation software for modeling multi-physics systems.

[0006] The magnetothermal coupling analysis module is used to construct a parameterized structural model based on the parameter scanning range obtained from the preliminary analysis of user design requirements by the control and interaction module. The parameterized structural model is used to perform parameterized scanning on the magnetic levitation bearing and motor to obtain structural parameters. The finite element software Ansys is then used to perform bidirectional coupled simulation of electromagnetic and temperature fields on the structural parameters to obtain magnetothermal coupling simulation results. The magnetothermal coupling simulation results include electromagnetic field simulation results and temperature field simulation results.

[0007] The control and interaction module includes a human-machine interface and a Simulink control system. The human-machine interface includes a parametric model area, a structural parameter design area, and a simulation result display area. The parametric model area is used to display the parametric model in real time; the structural parameter design area is used to obtain user design requirements and perform preliminary analysis to obtain the parameter scanning range; the simulation result display area is used to obtain and display the magnetothermal coupling simulation results output by the magnetothermal coupling analysis module and the dynamic simulation results output by the dynamic analysis module, and to perform multi-objective optimization on the magnetothermal coupling simulation results to obtain the optimal structural parameters of the magnetic levitation bearing and motor; the Simulink control system is used to construct the intelligent control algorithm model, electromagnetic force model, and sensor model of the magnetic levitation bearing and motor.

[0008] The dynamics analysis module is used to construct a parameterized model of the rotor system based on the optimal structural parameters output by the control and interaction module. It then calls Adams software to perform dynamic simulation analysis on the parameterized model of the rotor system, as well as the intelligent control algorithm model, electromagnetic force model, and sensor model constructed by the Simulink control system. This process continues until a parameterized model of the rotor system that meets the user's design requirements is obtained, and the final design parameters of the magnetic levitation bearing and motor are acquired. This completes the integrated development and design of the magnetic levitation bearing and motor and generates a design report.

[0009] In one embodiment, the magnetothermal coupling analysis module is used to obtain the parameter scanning range obtained by the control and interaction module from the preliminary analysis of the user's design requirements.

[0011] In one embodiment, the parameterized model area is used to display in real time the parameterized structural model constructed by the magnetothermal coupling analysis module and the rotor system parameterized model constructed by the dynamics analysis module.

[0012] In one embodiment, after obtaining the user's design requirements, the structural parameter design area calls AnsysElectronics software to perform a preliminary analysis of the user's design requirements, obtains the parameter scanning range, and displays it.

[0013] In one embodiment, the simulation results display area uses a multi-objective optimization algorithm in MATLAB to perform multi-objective optimization on the magnetic-thermal-mechanical coupling simulation results to obtain the optimal structural parameters of the magnetic levitation bearing and the motor.

[0014] In one embodiment, the human-computer interaction interface is designed based on the App Designer in MATLAB.

If the dynamic simulation results obtained from the analysis meet the user's design requirements, proceed to step 5; otherwise, continue to step 1.

[0020] Step 5: Output a parametric model of the rotor system that meets the user's design requirements and obtain the final design parameters of the magnetic levitation bearing and motor. Complete the integrated development and design of the magnetic levitation bearing and motor and generate a design report.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] In one embodiment, such as Figure 1 As shown, an integrated development system and method for magnetic levitation bearings and motors are provided.

[0030] The integrated development system for magnetic levitation bearings and motors includes: a magnetothermal coupling analysis module, a dynamic analysis module, and a control and interaction module;

[0031] The magnetothermal coupling analysis module is used to construct a parameterized structural model based on the parameter scanning range obtained from the preliminary analysis of user design requirements by the control and interaction module. This model is then used to perform parameterized scanning of the magnetic levitation bearing and motor to obtain structural parameters. The finite element software Ansys is then used to perform bidirectional coupled simulation of the electromagnetic and temperature fields on these structural parameters, yielding magnetothermal coupling simulation results. These results include electromagnetic field simulation results and temperature field simulation results. Based on these results, the electromagnetic and temperature rise characteristics of the magnetic levitation bearing can be understood. The electromagnetic and temperature field simulation results mainly contain electromagnetic force data, temperature rise data, eddy current loss data, and inductance values.

[0032] The control and interaction module includes the human-machine interface and the Simulink control system, such as... Figure 2 As shown, the human-computer interaction interface includes a parametric model area, a structural parameter design area, and a simulation result display area. The parametric model area is used to display the parametric model in real time; the structural parameter design area is used to obtain user design requirements and perform preliminary analysis to obtain the parameter scanning range; the simulation result display area is used to obtain and display the magnetothermal coupling simulation results output by the magnetothermal coupling analysis module and the dynamic simulation response results output by the dynamic analysis module, and to perform multi-objective optimization on the magnetothermal coupling simulation results to obtain the optimal structural parameters of the magnetic levitation bearing and motor; the Simulink control system is used to construct the intelligent control algorithm model, electromagnetic force model, and sensor model of the magnetic levitation bearing and motor.

[0033] The dynamics analysis module is used to construct a parameterized model of the rotor system based on the optimal structural parameters output by the control and interaction module. It then calls Adams software to perform dynamic simulation analysis on the parameterized model of the rotor system, as well as the intelligent control algorithm model, electromagnetic force model, and sensor model constructed by the Simulink control system. This process continues until a parameterized model of the rotor system that meets the user's design requirements is obtained, and the final design parameters of the magnetic levitation bearing and motor are acquired. This completes the integrated development and design of the magnetic levitation bearing and motor and generates a design report.

[0034] Furthermore, the integrated development system designed in this invention can also be applied to the design of integrated sensors in magnetic levitation bearings. In order to improve design efficiency, the system also introduces a database of commonly used design parameters, such as basic models of radial magnetic levitation bearings and permanent magnet synchronous motors with 8, 12, and 16 magnetic poles, so that users can directly select and apply them.

[0035] In one embodiment, the magnetothermal coupling analysis module is used to obtain the parameter scanning range obtained from the preliminary analysis of user design requirements by the control and interaction module. It then uses the control and interaction module to control Ansys Electronics software to construct a parameterized structural model. This model is used to perform parameterized scanning of the magnetic levitation bearing and motor, obtaining their structural parameters. Finally, Ansys Electronics and Ansys Workbench software are used to perform bidirectional coupled simulation of the electromagnetic and temperature fields on these structural parameters, obtaining the magnetothermal coupling simulation results. Specifically, the magnetothermal coupling analysis module determines, for example, the parameter scanning range obtained from the preliminary analysis of user design requirements by the control and interaction module. Figure 3 After scanning the parameter range as shown, as Figure 4 As shown, first select the simulation type, such as 2D, 3D, or UDP (User Datagram Protocol) simulation, then adjust the basic parameters of the magnetic levitation bearing and motor, and finally generate the parametric structural model with one click. Figure 4 The geometric model in the model is used to drive Ansys to perform simulation calculations.

[0036] In one embodiment, the optimal structural parameters of the magnetic levitation bearing and the motor include optimal electromagnetic force, optimal thermal field distribution, number of magnetic poles, optimal magnetic circuit, and optimal width-to-diameter ratio.

[0038] In one embodiment, such as Figure 5 As shown, after obtaining the user's design requirements, the structural parameter design area calls Ansys Electronics software to perform a preliminary analysis of the user's design requirements, obtains the parameter scan range, and displays it. Specifically, the structural parameter design area obtains the input user design requirements and exports a data file, including geometric parameter data, call ID for each calculation, and the type of calculation to be performed. Then, it invokes the Ansys Electronics script written in Python to perform calculations, determines whether the calculation type requires a graphical interface, selects the corresponding calculation method, obtains the parameter scan range, and displays it in the structural parameter design area.

[0039] In one embodiment, the simulation results display area uses a multi-objective optimization algorithm in MATLAB to perform multi-objective optimization on the magnetic-thermal-mechanical coupling simulation results to obtain the optimal structural parameters of the magnetic levitation bearing and the motor.

Then, use the finite element software Ansys to perform bidirectional coupled simulation of electromagnetic and temperature fields on the structural parameters to obtain magnetothermal coupling simulation results. The magnetothermal coupling simulation results include electromagnetic field simulation results and temperature field simulation results.

[0044] Step 3: Perform multi-objective optimization on the magnetothermal coupling simulation results to obtain the optimal structural parameters of the magnetic levitation bearing and motor, and call the Simulink control system to build the intelligent control algorithm model, electromagnetic force model and sensor model of the magnetic levitation bearing and motor.

[0045] Step 4: Construct a parameterized model of the rotor system based on the optimal structural parameters, and call Adams software to perform dynamic simulation analysis on the parameterized model of the rotor system, as well as the intelligent control algorithm model, electromagnetic force model, and sensor model constructed by the Simulink control system. If the dynamic simulation results obtained from the analysis meet the user's design requirements, proceed to step 5; otherwise, continue to step 1.

[0046] Step 5: Output a parametric model of the rotor system that meets the user's design requirements and obtain the final design parameters of the magnetic levitation bearing and motor. Complete the integrated development and design of the magnetic levitation bearing and motor and generate a design report.
