[0002] With the continuous improvement of power transmission levels and scale, spring components in operating mechanisms play a crucial role in high-voltage electrical appliances. The performance of spring components directly affects the reliability and safety of high-voltage circuit breakers. During the operation of high-voltage electrical appliances, spring components may experience performance degradation due to improper design, incorrect material selection, or manufacturing defects, leading to mechanical failures and affecting the safe and stable operation of the power grid.

[0003] In high-voltage electrical appliances, the operating environment of spring-operated mechanisms is typically harsh, subject to multiple environmental loads. Therefore, exploring the optimal structural parameters of the spring components in the operating mechanism and optimizing the operating mechanism are of great significance for improving the operational stability of high-voltage circuit breakers.

[0004] Existing research has limited scope for designing and optimizing the structure and parameters of spring components in operating mechanisms, and the relationship between the mechanical structural parameters during the operation of the operating mechanism and their impact on the mechanism's performance is incomplete. Therefore, it is urgent to analyze the structural parameters of springs in operating mechanisms, optimize the structural design, improve the mechanical distribution characteristics of the operating mechanism, and increase the safety margin during operation.

[0014] As a preferred embodiment of the design method for the spring component of the operating mechanism based on virtual prototyping technology described in this invention, the step of performing mechanical simulation analysis on the operating mechanism by repeatedly changing the spring structure parameters to obtain the mechanism contact force dataset includes: determining the variation range of the spring structure parameters, setting upper and lower limits for each parameter, generating several parameter combinations using a random sampling method, setting the corresponding spring structure parameters in the virtual prototyping software for each parameter combination to ensure that the parameters of other non-spring components remain unchanged, thereby isolating the influence of spring parameter changes on the simulation results; performing mechanical simulation analysis on the operating mechanism model under each parameter combination, including static analysis, dynamic analysis, and transient analysis; obtaining the contact force between the spring and other components during the simulation process; extracting the mechanism contact force data from the simulation results, including the magnitude, direction, and point of application of the contact force; preprocessing the collected data; classifying and storing the preprocessed contact force data according to the parameter combinations; and constructing a mechanism contact force dataset.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Example 1, referring to Figures 1-7 This is the first embodiment of the present invention, which provides a design method for an operating mechanism spring component based on virtual prototyping technology, including, for example... Figure 1 As shown:

[0034] S1. Obtain the geometric parameters of the operating mechanism and construct the structural model of the spring operating mechanism to be optimized.

[0035] The geometric parameters of the operating mechanism include its structure and dimensions. Based on the structure and dimensions of the operating mechanism, the basic geometric shapes of the transmission system, energy storage system and spring system are established respectively to ensure that the geometric parameters of each component match the actual dimensions, including but not limited to gears, shafts, bearings, springs, etc. The preliminary model is refined and necessary detailed features are added, including chamfers, holes, threads, etc.

[0036] Assemble the various subsystems (transmission system, energy storage system, and spring system), and check the assembled model for interference or gaps. If any are found, adjust the assembly structure to meet design requirements, ensuring proper fit and relative position between components. Figure 2 As shown.

[0037] S2. Apply boundary conditions to the structural model of the spring operating mechanism, and obtain the mechanical simulation parameters based on the dynamic simulation model of virtual prototyping technology.

[0038] Based on the actual working conditions of the operating mechanism, define the connection pair constraints between each component. For example, the connection between a gear and a shaft is defined as a rotary pair, and the connection between a bearing and the frame is defined as a fixed pair.

[0039] The contact between the spring and other components is controlled using an impact function to simulate the nonlinear characteristics of the actual contact process.

[0040] Set the initial conditions of the model, including initial position and initial velocity. Apply gravity load and driving force load according to the actual working conditions to simulate the actual working conditions. Perform preliminary simulation analysis on the model to obtain the accuracy and stability of the model.

[0041] Based on the simulation results, the model was adjusted and optimized. The adjusted and optimized spring operating mechanism structural model was then used for simulation to obtain the mechanical simulation parameters.

[0042] S3. Perform mechanical simulation analysis on the operating mechanism by changing the spring structure parameters multiple times to obtain the contact force dataset of the mechanism.

[0043] The structural parameters of the spring include the material shear modulus G of the spring in the operating mechanism, the spring wire diameter d, the spring major diameter d2, the effective number of spring coils n, the spring stiffness coefficient k, and the spring compression Δx.

[0044] The formula for calculating the spring stiffness coefficient is expressed as follows:

[0045]

[0046] Determine the range of variation for the spring structure parameters, and set upper and lower limits for each parameter. For example, determine the parameter range:

[0047] Material shear modulus G: The set range is 50-80 GPa.

[0048] Spring wire diameter d: The setting range is 2-5mm.

[0049] Spring major diameter d2: The setting range is 20-30mm.

[0050] Effective number of spring coils n: The setting range is 5-10 coils.

[0051] Spring stiffness coefficient k: Calculated based on material and geometric parameters, and not directly used as a variable.

[0052] Spring compression Δx: The setting range is 10-20mm.

[0053] Using a random sampling method, several parameter combinations are generated. For each parameter combination, the corresponding spring structure parameters are set in the virtual prototyping software to ensure that the parameters of other non-spring components remain unchanged, thereby isolating the influence of spring parameter changes on the simulation results.

[0054] Mechanical simulation analysis is performed on the operating mechanism model under each parameter combination to simulate the motion and force conditions of the operating mechanism under actual working conditions. The simulation time can be 10 seconds with a step size of 0.01 seconds. The simulation types include static analysis, dynamic analysis, and transient analysis. The adjustment of each parameter combination is as follows: Figure 3 As shown, the contact force between the spring and other components is obtained during the simulation. Contact force data every 0.1 seconds is extracted from the simulation results, including the magnitude, direction and point of application of the contact force. The collected data is preprocessed, and the preprocessed contact force data is classified and stored according to the parameter combination to construct the mechanism contact force dataset.

[0055] S4. Based on virtual prototyping technology, optimize the spring component of the operating mechanism by setting decision variables and optimization objectives. The optimization objective is to reduce the impact force on the operating mechanism parts and output the optimal structural parameters of the spring component of the operating mechanism.

[0056] Based on the variation range of the spring structure parameters, decision variables are determined. The decision variables are one or more parameters among the spring structure parameters. The optimization objective is set as minimizing the impact force on the operating mechanism parts. The impact force is evaluated through the mechanism contact force dataset.

[0057] An initial population is randomly generated based on an optimization algorithm. Each individual represents a set of decision variable values. Simulation analysis is performed on each individual to calculate the impact force on the operating mechanism parts, which is used as the fitness value. Based on the fitness value, excellent individuals are selected to enter the next generation. Crossover and mutation operations are performed on the selected individuals to generate new individuals. The evaluation, selection, crossover and mutation process is repeated until the termination condition is met. After the optimization process is completed, the individual with the smallest fitness value is output, which is the optimal structural parameter of the operating mechanism spring component. For example, the optimal parameters are: G = 70 GPa, d = 3.5 mm, d2 = 25 mm, n = 7 turns, k = 50 N / mm, Δx = 15 mm.

[0058] The cam collision contact force curves of the operating mechanism before and after optimization are as follows: Figure 4 and Figure 5 As shown, the force curves of the output crank arm of the operating mechanism before and after optimization are as follows: Figure 6 and Figure 7 As shown, the horizontal axis "time" represents time, and the vertical axis "force" represents stress.

[0059] Example 2, refer to Figure 8 This is the second embodiment of the present invention, which differs from the first embodiment in that: a system for designing a spring component of an operating mechanism based on virtual prototyping technology includes a model building module 100, a mechanical simulation parameter acquisition module 200, a contact force dataset acquisition module 300, and an optimal structural parameter output module 400; the model building module 100 acquires the geometric parameters of the operating mechanism and constructs a structural model of the spring operating mechanism to be optimized; the mechanical simulation parameter acquisition module 200 applies boundary conditions to the structural model of the spring operating mechanism and acquires mechanical simulation parameters based on the dynamic simulation model of virtual prototyping technology; the contact force dataset acquisition module 300 performs mechanical simulation analysis on the operating mechanism by changing the spring structural parameters multiple times, and acquires the contact force dataset of the mechanism; the optimal structural parameter output module 400 optimizes the spring component of the operating mechanism by setting decision variables and optimization objectives based on virtual prototyping technology, the optimization objective being to reduce the impact force on the operating mechanism parts, and outputs the optimal structural parameters of the spring component of the operating mechanism.
