Description

Technical Field

[0001] The present application belongs to the field of elevator technology, and in particular, relates to a method, device and storage medium for establishing an elevator simulation connection. Background Art

[0002] CAD, the full name of which is Computer Aided Design, is a technology and method that uses computers and their graphics processing capabilities to assist designers in design work. The main uses and functions of CAD software include but are not limited to: 2D drawing, 3D modeling, analysis and simulation, etc.

[0003] CAE, the full name of Computer Aided Engineering, is a process of simulating, predicting and optimizing the performance of engineering products or systems using advanced computer science and numerical algorithms. The core of CAE is to conduct quantitative analysis and simulation research on engineering problems through high-performance computing methods based on a variety of mathematical models and physical theories (such as finite element method, finite difference method, finite volume method, meshless method, etc.).

[0004] At present, the common way to create contact connections such as spot welding and gluing in the elevator design industry is: CAD designers physically mark the locations of spot welding or gluing in the model, such as generating a series of points or lines where welding points are required, and generating line geometry or surface geometry where gluing is required. There are many locations on the elevator that require spot welding or gluing. Marking the locations of spot welding or gluing in the model or generating reference points, lines, and surface geometries will increase the workload of CAD designers, and may also increase communication costs in subsequent CAE links. In some cases where rapid model iteration is required, due to the tight project development time, there may not be enough time to mark the locations of spot welding or gluing or generate reference points, lines, and surface geometries.

[0069] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0070] Embodiment 1

[0071] Figure 1 is a flow chart of a simulation connection creation method provided in an embodiment of the present application, such as Figure 1 As shown, the simulation connection creation method includes:

[0072] Step S101: Acquire a three-dimensional model of a target object established using three-dimensional modeling software.

[0073] The 3D modeling software can be CAD software, such as Figure 2 As shown, the target object may be an object with a large number of components such as an elevator car and a vehicle car, and some of the components need to be connected by gluing, some need to be connected by spot welding, and some need to be connected by bolts.

[0074] Exemplarily, a three-dimensional model of an elevator car created using CAD software may be obtained, the three-dimensional model consisting of component geometries.

[0075] The above method provided in the present application is mainly used in the pre-processing stage of the CAE simulation process. The pre-processing stage mainly involves model establishment, grid division and boundary condition setting. The above method provided in the present application specifically performs simulation creation of connections between components when dividing the grid.

[0076] Step S102: meshing the three-dimensional model of the target object to establish a finite element model.

[0077] In this step, the three-dimensional model of the target object is meshed using pre-processing software, and the continuous geometric model is discretized into a finite number of small units to obtain a finite element model.

[0078] Step S103: in the finite element model, identifying mesh region pairs whose spacing is within a preset distance range.

[0079] The mesh region pair includes two mesh regions that are geometrically adjacent; specifically, in the finite element model, a preset recognition algorithm is used to identify two mesh regions with contact characteristics within a preset distance range, and component information of the two mesh regions is obtained, as well as contact areas of the two mesh regions. The preset recognition algorithm may be a built-in algorithm of the Hypermesh software.

[0080] Each component in the finite element model is a mesh model. The two adjacent mesh surfaces of two similar components are connected together, and these two mesh surfaces constitute a mesh region pair.

[0081] The recognition of mesh area pairs is mainly based on the spacing between the two mesh areas. However, there will be errors in the spacing after the actual model is generated, so there will also be errors in the recognition of mesh area pairs. The error in mesh area pair recognition comes from the set distance tolerance, that is, the preset distance range. If the tolerance is too small, too few similar mesh areas will be recognized. If the tolerance is too large, too many similar mesh areas will be recognized. Generally, if there should be 0 gap between component geometries, but there will be errors when building the model, a smaller preset distance range can be set, such as less than 0.1, and the recognition of mesh area pairs with 0 gaps will be more accurate. If the preset distance range is too large, such as set to less than 0.2, the recognition of mesh area pairs with 0 gaps will be inaccurate.

[0082] Specifically, the built-in algorithm of Hypermesh software can be used to specify the search distance range, identify all mesh area pairs in the model whose distance is within the preset distance range, and record information such as the components where the two mesh areas are located and the size of the contact area. Figure 3 Shown is an identified grid region pair, including grid region 1 and grid region 2.

[0083] Step S104: determining a connection mode of the grid area pairs, and creating a simulation connection between the grid area pairs according to the connection mode.

[0084] The connection mode of mesh area pairs can be contact connection, adhesive connection or spot welding connection. Contact connection means that the two parts are not adhesively connected or spot welded, but may be connected by bolts, and the surfaces of the two parts are in contact with each other. Adhesive connection means that the surfaces of the two parts are glued together. Spot welding connection means that the surfaces of the two parts are welded together.

[0085] In some embodiments, the above step S104 may be implemented as: determining that the connection mode of the mesh area pair is a contact connection, and creating a simulated contact connection between the mesh area pair.

[0086] like Figure 3As shown, after the mesh area pair is identified, it is also identified that there are bolt holes on mesh area 1, so it can be determined that the mesh area pair is connected by bolts, so the mesh area pair is contact connected, not adhesively connected or spot welded. In addition, the user can determine the connection method of the mesh area pair through the drawing, so it can be determined that the mesh area pair is contact connected according to the instructions entered by the user. After determining that the connection method of the mesh area pair is contact connection, create a simulated contact connection between the mesh area pairs. Users can select multiple mesh area pairs to create batches with one click.

[0087] In some embodiments, the above step S104 may be implemented as: determining that the connection mode of the mesh area pairs is an adhesive connection, and creating a simulated adhesive connection between the mesh area pairs.

[0088] Specifically, when creating the simulated adhesive connection between the mesh area pairs, two components where the two mesh areas in the mesh area pair are located can be determined first, and then simulated adhesive connections are created for all mesh area pairs belonging to the two components, which can improve the creation speed of the simulated adhesive connection.

[0089] In actual applications, users can determine the connection method of mesh area pairs through drawings, so they can determine that the mesh area pairs are glued according to the instructions entered by the user, and then create simulated glue connections between the mesh area pairs. Users can select multiple mesh area pairs to create batches with one click.

[0090] For example, Figure 4 As shown, the grid area 1 and the grid area 2 in the grid area pair are connected by gluing, the grid area 1 is a reinforcing rib, the grid area 2 is a side of the elevator car, and the reinforcing rib is fixed to the elevator car by gluing to reinforce the elevator car.

[0091] In some embodiments, the above step S104 may be implemented as: determining that the connection mode of the mesh area pair is a spot welding connection, and creating a simulated spot welding connection between the mesh area pair.

[0092] In practical applications, users can determine the connection method of mesh area pairs through drawings, so they can determine that the mesh area pairs are spot welded according to the instructions input by the user, and then create simulated spot welded connections between the mesh area pairs.

[0093] For example, Figure 5 As shown, the grid area 1 and the grid area 2 in the grid area pair are connected by spot welding, the grid area 1 is a frame, the grid area 2 is a side of the elevator car, and the frame is fixed on the elevator car by spot welding. Figure 5 The six simulated solder joints created are shown in FIG.

[0094] Specifically, the step of creating a simulated spot welding connection between the grid area pair comprises: determining a spot welding area and welding point arrangement information on any grid area in the grid area pair, and creating welding points in the spot welding area according to the welding point arrangement information.

[0095] like Figure 6 As shown, the solder joint arrangement information includes: starting point offset, solder joint spacing, solder joint quantity and arrangement direction. The starting point offset refers to the distance from the starting point to the first solder joint in the arrangement direction after the spot welding area is selected.

[0096] Specifically, when determining the spot welding area and the arrangement information of the welding points on any grid area in the grid area pair, a regular area that meets the preset shape can be determined in the grid area, and then the starting point offset, welding point spacing, welding point quantity and arrangement direction of the welding points are determined in this regular area. The preset shape can be a regular shape such as a square, a rectangle, a circle, etc.

[0097] For spot welding connections, how to quickly determine the location of the welding point without a reference position of the welding point is the most critical core requirement. This application can determine the relatively accurate location of the welding point. Figure 6 As shown, based on the solder joint drawing, after the user fills in the solder joint spacing and the number of solder joints (generally there will be intuitive markings on the drawing), select the grid area where the solder joints are located. The area where the solder joints are located is generally a relatively regular area, so the distribution size of the solder joints in the area can be automatically calculated by selecting the size of the grid area and solder joints can be created in batches.

[0098] The simulation connection creation method of the embodiment of the present application is to obtain a three-dimensional model of a target object established by using three-dimensional modeling software; to mesh the three-dimensional model of the target object and establish a finite element model; in the finite element model, to identify pairs of grid areas with spacing within a preset distance range; to determine the connection method of the grid area pairs, and to create a simulation connection between the grid area pairs according to the connection method. Compared with the prior art, the present application does not require the three-dimensional model designer to separately mark the locations of spot welding or gluing in the model or generate reference points, lines, and surface geometries. In the finite element model creation link, based on the above method of the present application, the user only needs to specify the connection method of similar grid area pairs to quickly create the corresponding simulation connection, thereby improving work efficiency and reducing communication costs between designers.
