[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Example 1, reference Figure 1-Figure 7 , which is the first embodiment of the present invention, and provides a design method for a spring component of an operating mechanism based on virtual prototype technology, including: Figure 1 As shown:

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

[0035] The geometric parameters of the operating mechanism include its structure and size. According to the structure and size 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 are consistent with the actual size, including but not limited to gears, shafts, bearings, springs, etc. The preliminary constructed model is refined and necessary detail features including chamfers, holes, threads, etc. are added.

[0036] Assemble each subsystem (transmission system, energy storage system and spring system) and check whether there is interference or gap in the assembled model. If so, adjust the assembly structure to meet the design requirements and ensure the correct fit and relative position between the components, such as Figure 2 shown.

[0037] S2. Boundary conditions are applied to the spring operating mechanism structure model, and the mechanical simulation parameters are obtained by the dynamic simulation model based on the virtual prototype technology.

[0038] According to the actual working conditions of the operating mechanism, the connection pair constraints between the components are defined. For example, the connection between the gear and the shaft is defined as a rotating pair, and the connection between the bearing and the frame is defined as a fixed pair.

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

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

[0041] According to the simulation results, the model is adjusted and optimized, and the adjusted and optimized spring operating mechanism structure model is used for simulation to obtain the mechanical simulation parameters.

[0042] S3. The spring structural parameters are changed multiple times to perform mechanical simulation analysis on the operating mechanism to obtain a contact force data set of the mechanism.

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

[0044] The calculation formula of the spring stiffness coefficient is expressed as,

[0045]

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

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

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

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

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

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

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

[0053] A random sampling method is used to generate several parameter combinations. For each parameter combination, the corresponding spring structure parameters are set in the virtual prototype software to ensure that the parameters of other non-spring components remain unchanged, so as to isolate the impact of spring parameter changes on the simulation results.

[0054] Perform mechanical simulation analysis on the actuator model under each parameter combination to simulate the motion and force of the actuator under actual working conditions. The simulation time can be 10 seconds, the step length is 0.01 seconds, and the simulation types include static analysis, dynamic analysis and transient analysis. The adjustment of each parameter combination is as follows: Figure 3 As shown; during the simulation process, the contact force between the spring and other components is obtained, and the contact force data every 0.1 second is extracted from the simulation results, including the magnitude, direction and point of action 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 a mechanism contact force data set.

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

[0056] According to the variation range of the spring structure parameters, the decision variables are determined. The decision variables are one or several parameters of the spring structure parameters. The optimization goal is set to minimize the impact force on the parts of the operating mechanism. The impact force is evaluated through the mechanism contact force data set.

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

[0058] The collision contact force curves of the operating mechanism cam before and after optimization are shown in Figure 4 and Figure 5 As shown in the figure, the force curves of the upper hole 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, reference Figure 8 , which is the second embodiment of the present invention, and is different from the first embodiment in that: a system for a design method of an operating mechanism spring component based on virtual prototype technology, comprising a model building module 100, a mechanical simulation parameter obtaining module 200, a contact force data set obtaining module 300 and an optimal structural parameter output module 400; the model building module 100 obtains the geometric parameters of the operating mechanism and constructs a spring operating mechanism structural model to be optimized; the mechanical simulation parameter obtaining module 200 applies boundary conditions to the spring operating mechanism structural model and obtains mechanical simulation parameters based on the dynamic simulation model of the virtual prototype technology; the contact force data set obtaining module 300 changes the spring structural parameters for multiple times to perform mechanical simulation analysis on the operating mechanism and obtains the mechanism contact force data set; the optimal structural parameter output module 400 optimizes the operating mechanism spring component based on the virtual prototype technology by setting decision variables and optimization targets, the optimization target is to reduce the impact force on the operating mechanism parts, and output the optimal structural parameters of the operating mechanism spring component.
