[0021] It should be understood that the specific embodiments described here are only used to explain the technical solutions of this application and are not used to limit this application.

[0022] To better understand the technical solutions of this application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific embodiments.

[0023] The main solution of the embodiment of this application is: obtaining the position information of each part of the target device model in multiple different postures; performing mesh division on the target device model in the initial posture, where the initial posture is one of the multiple different postures; in response to selecting the target posture, calculating the coordinate transformation matrix based on the mesh division result in the initial posture and the position information of each part in the target posture; based on the coordinate transformation matrix, transforming each mesh in the initial posture to obtain a transformed model; adding working condition information to the transformed model to obtain the solution file of the target device model in the target posture.

[0024] In the related art, with the development of automated production, finite element analysis is particularly important in industrial applications. Finite element analysis can accurately simulate the stress and deformation of complex mechanical systems under various load conditions.

[0025] However, in order to adapt to the variable working postures of the machine, it is necessary to frequently adjust the finite element model. Due to the complex changes in the positions and angles of the parts of the machine in different postures, mesh generation needs to be carried out repeatedly, which makes the whole process cumbersome and time-consuming, and is also prone to human errors, resulting in low efficiency.

[0026] In summary, how to improve the efficiency of finite element analysis of mechanical equipment is an urgent problem to be solved at present.

[0027] Based on this, the present application provides a solution, so that during the process of finite element analysis of mechanical equipment, there is no need to re-perform mesh cutting during the conversion between different postures, which improves the conversion efficiency and avoids human errors.

[0028] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a posture adjustment device capable of implementing the above functions. The following takes the posture adjustment device as an example to illustrate this embodiment and the following embodiments.

[0029] Refer to Figure 1 , Figure 1 shows a schematic flow chart of a posture adjustment method provided by an embodiment of the present application. The posture adjustment method can be applied to a posture adjustment device, including the following steps S110 to step S130: Step S110, obtain the position information of each part of the target device model in multiple different postures.

[0030] Among them, the target device refers to the mechanical equipment used for testing. Generally, a mechanical equipment can be composed of multiple parts, and through the cooperation between the parts, different posture adjustments can be realized. The target device model refers to the modeling of the mechanical equipment (target device), for example, it can be a 3D model in drawing software such as CAD and Solidworks.

[0031] In this embodiment, the finite element analysis scenario is involved. Finite Element Analysis (FEA) is a numerical calculation method widely used in the engineering field to solve complex physical problems. Its core idea is to divide the continuous physical structure into a finite number of small units (i.e., meshes), and connect these meshes through connecting elements to form a discrete mesh structure.

[0032] In some implementation manners, for each posture of the target device model, there may be a corresponding posture file in advance.

[0033] In this embodiment, the reading operation can be performed by geometric processing software. For example, software such as ANSYS SpaceClaim Direct Modeler (SCDM), Blender, ABAQUS, etc. can be used for reading.

[0034] Taking SCDM and CAD processing the pose file as an example, the staff can import the pose file into CAD and parse and extract the position of each part in the pose file through a pre-set script. For example, the position of the part can be extracted through "import clr; clr.AddReference('SpaceClaim.Api.V18'); import SpaceClaim.Api.V18 as sc; doc = sc.Document.Open('model.scdoc'); part = doc.Parts[i]; position = part.Position;", and the position of the part can be saved as the position information in step S110.

[0035] Among them, the position of the part referred to in this embodiment can be coordinates. For example, all parts can be in a pre-fixed coordinate system (such as a global coordinate system), and the coordinate values of the key points of each part (such as pre-set sampling points) can represent the position of the part described in this embodiment.

[0036] In some embodiments, after all the model files corresponding to each pose are imported, the part recognition and position parsing operations can be performed together; in other embodiments, the part recognition and position parsing operations can be performed on the model files corresponding to each pose in sequence. This embodiment does not make a limitation here.

[0037] Step S120, perform mesh division on the target device model in the initial pose.

[0038] In some embodiments, for multiple different poses of the target device model, any one of them can be selected as the initial pose, and the initial pose file corresponding to the initial pose is read; multiple parts are extracted from the initial pose file; based on the multiple parts, the corresponding mesh is divided.

[0039] Specifically, based on the initial pose file, for each part, the corresponding mesh can be divided based on the position of the part. That is, each part corresponds to a mesh. In other feasible embodiments, the mesh division can also be performed manually according to the specific requirements of the staff. This embodiment does not make a limitation here.

[0040] After obtaining the mesh, connection elements can be created for different meshes. A connection element refers to a special element used to connect meshes of different parts. These connection elements are usually used to simulate connections, constraints, or load transfer in a structure. As an example, connection elements can include rbe2, rbe3, join, cbeam, crod, etc., which are not limited in this embodiment.

[0041] In addition, after the connection elements are created, operations such as property definition can also be performed on the connection elements and the mesh.

[0042] Step S130, in response to selecting a target pose, calculate a coordinate transformation matrix based on the mesh division result of the initial pose and the position information of each part in the target pose.

[0043] It can be understood that regardless of the pose change, the part structure of the mechanical equipment itself does not change, but only the position changes.

[0044] Therefore, in order to accurately infer "how the model will change after the pose change", in some embodiments, the position change relationship between different poses can be calculated based on the positions of the foregoing parts, that is, the coordinate transformation matrix described in this embodiment.

[0045] Specifically, the first position information of each part in the target device model in the target pose and the second position information in the initial pose can be obtained; based on the first position information and the second position information, the corresponding coordinate transformation matrix is determined.

[0046] Among them, the three-point calibration method can be used, that is, the first position information is the coordinate values of three specified sampling points on the part in the initial pose in the foregoing global coordinate system, and the second position information is the coordinate values of the same three specified sampling points on the part in another pose (i.e., the target pose) in the foregoing global coordinate system.

[0047] Thus, we obtain the coordinate transformation matrix when converting from the initial pose to the target pose. In some embodiments, the coordinate transformation matrices corresponding to converting from the initial pose to any target pose can be calculated uniformly and all saved in a local file, and directly extracted and used when specifically used, which is not limited in this embodiment.

[0048] In this embodiment, for the preprocessing of the finite element (i.e., the foregoing steps S110 to S130), HyperMesh software can be selected. The user can select a target pose among various poses of the target device model in the HyperMesh interface. Based on the foregoing saved local file, the coordinate transformation matrix corresponding to the target pose can be determined.

[0049] Step S140: Based on the coordinate transformation matrix, transform each grid in the initial pose to obtain a transformation model.

[0050] For any grid, it can be processed through a preset script of Tool Command Language (TCL), and the corresponding coordinate transformation matrix is used for grid transformation to obtain the transformed grid. The combination of multiple transformed grids forms the transformation model described in this embodiment, which is essentially a model obtained by recombining the displacements and rotations of the parts in the target device model.

[0051] It can be understood that after the pose changes, the connection unit will also change accordingly. In some embodiments, after obtaining the transformation model, the repaired connection unit can also be calculated based on the initial connection unit and the initial attribute information, and the repaired connection unit is added to the transformation model. Among them, the repaired connection unit can also be the aforementioned rbe2, rbe3, join, cbeam, crod, etc.

[0052] Step S150: Add working condition information to the transformation model to obtain a solution file of the target device model in the target pose.

[0053] In FEA, the working condition information refers to various external conditions and constraints applied to the model during the simulation process, including but not limited to loads, boundary conditions, initial conditions, etc. These information are crucial for accurately simulating and analyzing the behavior of physical systems.

[0054] After the user adds the working condition information, the model can be exported to form a solution file. The FEM solution file is a file containing finite element model information, which is usually used in engineering applications such as structural analysis, optimization, and simulation. As an example, the solution file can be a file in the.fem format, and the content is usually ASCII and can be opened by a text editor.

[0055] This embodiment provides a pose adjustment method. By obtaining the position information of each part of the target device model in multiple different poses, and performing mesh division on the target device model in the initial pose, in response to selecting the target pose, based on the mesh division result in the initial pose and the position information of each part in the target pose, calculate the coordinate transformation matrix, so as to transform each of the grids in the initial pose based on the corresponding target transformation matrix to obtain a transformation model, and add working condition information to the transformation model to obtain a solution file of the target device model in the target pose, which avoids re-meshing during the pose conversion process, improves efficiency, reduces the workload of repeated modeling, eliminates manual operation errors, and improves the intelligence and accuracy of the analysis process.
