Description

Technical Field

[0001] This invention relates to the field of simulation technology, and more specifically, to a method, system, medium, and equipment for simulating and analyzing the wear of optoelectronic rotary connectors. Background Technology

[0002] In the operational state of an optoelectronic rotary connector, as the brush ring rotates, wear occurs between the brush filaments and the V-groove of the brush ring. Typically, studying this wear requires prototyping and conducting numerous repeated experiments simulating actual working conditions. Experimental wear studies provide reliable data, but require a large number of test specimens. While finite element method (FEM) simulations can be performed without limit on the number of simulations, at virtually no cost, the drawback is that simulation results may deviate significantly from reality due to variations in the model, constraints, loads, mesh, and wear theory. Therefore, combining experimental and simulation methods can leverage the advantages of both.

[0003] Most existing finite element analysis software lacks native wear simulation capabilities, requiring secondary development to create wear models. The mechanism of wear is relatively complex. The most commonly used theoretical model is the Archard wear model, which was first proposed by Archard et al. in 1953 and has been improved over the following decades. It has been applied to the finite element platform for solving. For example, Li Congbo et al. proposed a method for analyzing the wear of machine tool guideways based on the Archard model and finite element simulation test in their paper "Wear Model and Finite Element Analysis of Machine Tool Guideways Based on Archard Model" in the Journal of Mechanical Engineering (2016, 52(15):106-113), and conducted simulation tests using the ANSYS platform. Chang Kai used ANSYS to simulate the wear of O-ring seals in his paper "Research on Wear Simulation Method of O-ring Seals Based on ANSYS" in Hydraulics and Pneumatics (2018(02):98-103), and solved the problem of material loss during wear that is difficult to simulate by the ANSYS platform through programming. Abaqus, as another commonly used finite element platform, supports calling user subroutines for secondary development to realize the function of wear simulation. For example, Bose and Ramkumar proposed a method for analyzing the wear of O-ring seals based on the Archard model and finite element simulation test in their paper "Proceedings of...". In her paper "Finite element method based slidingwear prediction of steel-on-steel contacts using extrapolation techniques" published in "Institut ion of Mechanical Engineers" (2019; 233(10):1446-1463), wear simulation was performed using the Umeshmot ion user subroutine of the Abaqus platform and the Arbitrary Lagrangian–Eulerian method, and the results were verified by experiments. In her paper "Research on the Wear Mechanism of Carbide Tools Based on ABAQUS Finite Element Simulation" published in Machine Tools and Hydraulics, Lü Na used Abaqus to establish a finite element model of carbide tool turning and simulated the wear of the tool.

[0004] However, in general, wear simulation is often prone to non-convergence due to the complexity of the working conditions and various factors. Therefore, it is necessary to make certain improvements to the simulation model and method according to specific cases. Summary of the Invention

[0061] The controller includes the computer-readable storage medium storing the computer program described above, or the controller includes the wear simulation analysis system for the photoelectric rotary connector described above.

[0062] Example 2

[0063] Example 2 is a preferred example of Example 1.

[0064] This invention proposes a wear simulation analysis method for optoelectronic rotary connectors. The wear components include brush filaments and a brush ring. As the brush ring rotates, friction occurs between the brush filaments and the V-groove of the brush ring, leading to wear. This simulation method uses the Abaqus platform, simplifying the wear model of the brush filaments and brush ring as friction between a rigid body and a deformable body. The simulation steps are divided into multiple analysis steps. In each analysis step, the contact pressure of the deformable body is calculated. Based on the principle of the Archard model, the contact pressure value of the node is multiplied by the wear coefficient to obtain the regression displacement of the node. Through continuous iteration of multiple analysis steps, the contact wear between the brush ring and brush filaments is discretely simulated.

[0065] Specifically, the wear simulation analysis method for the optoelectronic rotary connector includes:

[0066] Simplified model and import steps: For brush bristles and brush rings, only the area near the contact point needs to be retained; other parts have little impact on wear analysis and can be deleted. Figure 1 The model shown is simplified to Figure 2The model is shown below. After simplifying the model in other 3D modeling software, import the model into Abaqus. Create two sets of simulation models. In one set, the brush filaments are set as deformable bodies and the brush ring as a discrete rigid body. In the other set, the brush ring is set as a deformable body and the brush filaments are set as rigid bodies (discrete rigid bodies or geometric rigid bodies). The former simulates the wear of the brush filaments without considering brush ring wear, and the latter simulates the wear of the brush ring without considering brush filament wear. After importing, set a reference point RP on the rigid body component, with the reference point coordinates set at the contact point.

[0067] (2) Set and assign material properties: When the part is a deformable body, set the material properties. The brush bristle material is AuNi9, the Young's modulus is set to 96236 MPa, and the Poisson's ratio is 0.3; the brush ring material is copper, the Young's modulus is set to 119000 MPa, and the Poisson's ratio is 0.3.

[0068] (3) Assembly: Instantiate the brush ring and bristle components and assemble them. Figure 2 The point of contact between the two is set as the origin of the coordinate system.

[0069] (4) Set analysis steps and ALE adaptive mesh properties: Set several analysis steps, the number of which depends on the number of frames to be simulated. In each analysis step, set the ALE adaptive mesh with parameters of volume 0.5, initial configuration projection 0.5, initial characteristic angle 30, and transition characteristic angle 30.

[0070] The motion of nodes can be defined using user subroutines in conjunction with ALE adaptive meshes, and the motion of nodes is related to the contact pressure of the current node; ALE adaptive mesh properties can be assigned to flexible bodies;

[0071] The user subroutine is:

[0072]

[0073]

[0074] (5) Set the interaction: Set the mechanical-interaction-tangential behavior to "frictionless"; set the mechanical-interaction-normal behavior to "hard contact"; and set the constraint execution method to "Standard". Add the interaction to the two contact surfaces, with the primary surface being the rigid body contact surface and the secondary surface being the deformable body contact surface.

[0075] (6) Setting loads and constraints: When the brush bristles are deformable bodies, set both end faces as completely fixed constraints. Figure 3 When the brush ring is a deformable body, one of its non-contact surfaces is set as a completely fixed constraint. Figure 4For a rigid body, constraints are placed on the reference point RP, constraining its 6 degrees of freedom. For static analysis without considering friction, a force load of 0.3 N is added to the rigid body reference point RP, perpendicular to the deformable body's normal and pointing inwards. To simulate the process of the rigid body continuously pressing into and wearing down the deformable body, no load needs to be defined; the boundary conditions of the rigid body are directly modified. For example, in the first analysis step, the rigid body presses into the deformable body by 0.003 mm; in the second analysis step, it is set to 0.006 mm; in the third analysis step, it is set to 0.009 mm, and so on.

[0076] (7) Mesh settings: Flexible body mesh is set to mainly hexahedron, element type C3D8; Discrete rigid body (shell) mesh is set to mainly quadrilateral, element type R3D4; Geometric rigid body mesh is not set;

[0077] (8) Call the user subroutine to submit the job analysis;

[0078] The subroutine specifies a k value as the wear coefficient and extracts the contact pressure value of the node in Abaqus. Multiplying this coefficient by the pressure value yields the wear ablation amount of the node in that analysis step. The job calls the specified subroutine file with the .for suffix, submits the job, and waits for the analysis results.

[0079] (9) Results visualization: View the analysis results in Abaqus and plot cloud maps.

[0080] The above analysis steps are as follows: Figure 5 As shown.

[0081] Example 3

[0082] Example 3 is a preferred example of Example 1.

[0083] The simulation of brush bristle wear on the brush ring (where the bristles are rigid and the brush ring is deformable) will be used as an example for further explanation. The simulation flowchart is shown below. Figure 5 This includes the following steps:

[0084] (1) Simplify and import the model, and set up rigid bodies and deformable bodies;

[0085] (2) Establish and assign material properties;

[0086] (3) Assembly;

[0087] (4) Set the analysis step and ALE adaptive mesh properties;

[0088] (5) Set up interactions;

[0089] (6) Set loads and constraints;

[0090] (7) Grid settings;

[0091] (8) Call the user subroutine and submit the analysis;

[0092] (9) Results visualization.

[0093] The following is a detailed explanation of each step.

[0094] (1) Simplify and import the model, and set rigid and deformable bodies. Import the simplified model of the brush ring and set it as a deformable body; draw the model of the brush bristles (a section of cylindrical arc surface) in Abaqus and set it as a geometric rigid body.

[0095] (2) Establish and assign material properties. Create a new material, select Mechanics-Elasticity-Elasticity, set Young's modulus to 119000 MPa, Poisson's ratio to 0.3, and assign it to the section on the brush ring.

[0096] (3) Assembly. Instantiate the brush ring and bristle components and move them to the correct positions, such as... Figure 2 As shown.

[0097] (4) Set the analysis steps and ALE adaptive mesh properties. Set 25 analysis steps, each representing the brush ring rotating 1.25°. When the simulated rotation reaches 7.5°, it returns to the 0° position and performs the second iteration, and so on. There are a total of 5 iterations for the 25 analysis steps. In each analysis step, the geometric nonlinearity is set to "on", and the ALE adaptive mesh is set with parameters of volume 0.5, initial configuration projection 0.5, initial characteristic angle 30°, and transition characteristic angle 30°. Set its motion to "user-defined", that is, define its motion through a user subroutine and assign the ALE adaptive mesh properties to the brush ring.

[0098] (5) Set the interactions. Set the mechanical-interaction-tangential behavior to "frictionless"; set the mechanical-interaction-normal behavior to "hard contact"; and set the constraint enforcement method to "penalty (Standard)". Add the interactions to the two contact surfaces, with the primary surface being the brush filament contact surface and the secondary surface being the brush ring contact surface.

[0099] (6) Set loads and constraints. Set one non-contact surface of the brush ring as a completely fixed constraint. Figure 4 The six degrees of freedom of the brush bristle reference point RP are constrained, and the values ​​of these six degrees of freedom are continuously modified to change the position of the brush bristles. The movement of the brush bristles is divided into lateral and longitudinal movements. The lateral movement is parallel to the axis of the brush bristles, rotating 1.25° around the axis of the brush ring in each analysis step. After rotating 7.5 degrees, the brush bristles are moved back to the initial position; this is one iteration. A second iteration is then performed, and so on. Before the second iteration, the brush bristles must first be moved radially inward towards the brush ring (corresponding to increased wear depth) by a certain distance; this is the longitudinal movement of the brush bristles. Figure 6 As shown.

[0100] (7) Mesh Settings. The brush ring mesh is set to primarily hexahedral, element type C3D8; the brush filaments are geometric rigid bodies and do not require meshing. Figure 7 ).

[0101] (8) Call the user subroutine and submit it. Write the user subroutine described above, and call it in the job manager to submit the job.

[0102] (9) Result Visualization. Set the plotting data as a displacement diagram, and select the displacement data in the U-U2 direction (in this example, this direction is parallel to the normal of the contact surface) to plot a contour map. Figure 8 ); and use the slice function to observe the cross-section of the brush ring ( Figure 9 ); Select CPREES data to plot a chromatogram and obtain the pattern of the contact patch. Figure 10 ).

[0103] As can be seen from the analysis results, this simulation method can obtain very intuitive wear simulation results.

[0104] Those skilled in the art will understand that, in addition to implementing the system, apparatus, and their modules provided by this invention in purely computer-readable program code, the same program can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps.
