Based on this, the embodiment of the application provides a method and a device for adjusting a rigging grid, and an electronic device, by which the technical problem of low operation efficiency of simplifying and modifying the rigging grid can be alleviated.
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a method for adjusting a rigging grid according to an embodiment of the present application. Wherein, the method can be applied to terminal equipment capable of presenting a graphical user interface. As shown in fig. 1, the method includes:
step S110, obtain the rigging grid to be adjusted.
The lockset mesh to be adjusted comprises a plurality of vertexes, wherein each vertex records attribute information, and the attribute information is used for recording the coordinates and the vertex types of the vertexes.
For some parts of the rigging grid, modifications and simplifications are needed without affecting the Finite Element Analysis (FEA) results. For example, in the double-ring buckle model, the pin roll part in the original model file has a single cylinder liner primitive which can be seen through a two-dimensional drawing, while the original model file is opened by software to find that the original model file is a solid cylinder, for example, in the double-ring buckle two-dimensional drawing shown in fig. 2, the connection part between the single cylinder liner primitive and the pin roll before modification is shown as a part in a ring 301 in fig. 3.
And step S120, optimizing the vertex type of the rigging grid to be adjusted by using the trained grid optimization network to obtain the optimized rigging grid.
The principle of optimization of the rigging grid is simplified without affecting the finite element analysis results (i.e. whether it participates in the stress analysis results of the rigging grid to be adjusted). For the understanding of finite element analysis, it is solved by replacing the complex problem with a simpler one. Finite element analysis may consider a solution domain as consisting of many small interconnected subdomains called finite elements, assuming a suitable approximate solution for each element, and then deriving the overall satisfaction conditions (e.g., structural equilibrium conditions) for solving this domain, so that the solution finite element method to solve the problem fundamentally differs from other approximation methods for solving edge-value problems in that its approximation is limited to relatively small sub-domains, finite element methods define functions over the domain of elements of simple geometry (e.g., triangles or arbitrary quadrilaterals in two-dimensional problems) (piecewise functions) and do not consider the complex boundary conditions of the entire definition domain, which is one of the reasons why finite element methods outperform other approximation methods. The basic steps of finite element solvers are the same for problems of different physical properties and mathematical models, except that the specific formula derivation and the computational solution are different. The basic steps of finite element solving the problem may be:
first step problem and solution domain definition: determining the physical property and the geometric area of a solution domain approximately according to the actual problem; and a second step of solving domain discretization: the solution domain is approximated to be a discrete domain composed of a limited number of units which have different limited sizes and shapes and are connected with each other, which is conventionally called finite element network division, obviously, the smaller the unit (the thinner the network is), the better the approximation degree of the discrete domain is, the more accurate the calculation result is, but the calculation amount and the error are increased, so that the discretization of the solution domain is one of the core technologies of the finite element method; thirdly, determining a state variable and controlling the state variable: a particular physical problem can be represented generally by a set of differential equations containing the boundary conditions of the problem state variables, which are typically formulated into equivalent functional forms for finite element solution; the fourth step is derived by a unit: a proper approximate solution is constructed for the units, namely a finite unit column is deduced, wherein a reasonable unit coordinate system is selected, a unit trial function is established, the discrete relation of each state variable of the units is given in a certain method, and therefore a unit matrix (a rigidity matrix or a flexibility matrix in structural mechanics) is formed. For engineering applications, it is important to note the problem solving performance and constraints of each unit. For example, the shape of the cell should be regular, and when the cell is deformed, not only the accuracy is low, but also the risk of lacking rank exists, which may result in being unable to solve; and fifthly, final assembly solving: the units are assembled to form a total matrix equation (a combined equation set) of a discrete domain, the requirement of the discrete domain of an approximate solution domain is reflected, namely the continuity of a unit function needs to meet a certain continuous condition, the assembly is carried out at nodes of adjacent units, and the continuity of state variables and derivatives (if possible) thereof is established at the nodes; solving and result interpretation of a sixth step simultaneous equation set: the finite element method finally results in a simultaneous equation set, and the solution of the simultaneous equation set can be a direct method, a substitution method and a random method. The solution results are approximate values of the state variables at the cell nodes, and for the quality of the calculation results, it will be evaluated and determined whether repeated calculations are required by comparison with the allowable values provided by the design criteria.
For the process of simplification and modification of the rigging grid, for example, the actual single cylinder liner primitive also includes other components, and since this portion has substantially no influence on the finite element analysis result (i.e., substantially does not participate in influencing the stress of the rigging grid to be adjusted), the simplification can be performed by replacing the single cylinder liner primitive with a stepped shaft model, and the connection portion between the modified single cylinder liner primitive and the pin shaft is shown as the portion in circle 401 in fig. 4. For another example, for a rotating hook, the model was imported into ANSYS to find that the model displayed incompletely. In SolidWorks, partial solid bodies in the rotating hook model file are checked to be curved surface solid bodies, and the hook body only has an outer surface without the solid bodies by utilizing a cross section. The tongue portion of the rotating hook model before processing is shown as the portion in the loop 501 in fig. 5. Therefore, the model is to be curved and stitched, and the tongue in the model does not affect the finite element analysis result (i.e. does not affect the stress participating in the rigging mesh to be adjusted), the model can be eliminated from simplification, and the main difference between the rotation hook model before processing and the rotation hook model after processing is shown as the part in the ring 601 in fig. 6, i.e. the part without tongue in the ring 601 in the rotation hook model after processing. It can be seen that in contrast to the previous figures, the tongues have been omitted. It follows that the modification and simplification of the rigging grid is a simplification without affecting the results of the above-described finite element analysis (i.e. without affecting the stresses involved in the rigging grid to be adjusted).
And step S130, carrying out primitive splitting on the optimized rigging grid based on the optimized vertex type to obtain the split rigging grid.
Through the lockset mesh to be adjusted comprising the plurality of vertexes recorded with the coordinate for recording the vertexes and the attribute information of the vertex types, the optimized rigging mesh can be subjected to primitive splitting based on the optimized vertex types, and then the split rigging mesh is obtained.
Step S140, providing a graphical user interface containing the split rigging grids through the terminal equipment, and displaying different graphic elements in a differential mode.
In this step, the separated rigging grids can be displayed on a computer screen, wherein different primitives are displayed differently.
Step S150, in response to the designated operation for the target position node on the split rigging grid, determining a target primitive corresponding to the target position node on the split rigging grid.
Illustratively, a user clicks a certain position point on a rigging grid to be adjusted through operation, and the terminal device determines a target primitive corresponding to the rigging grid after the target position node is split.
And step S160, displaying the simplified control aiming at the target graphic element in the graphical user interface.
In this step, a simplified part of the first rigging grid may be displayed at the target location node through a dotted line, and the dotted line is correspondingly prompted to indicate a simplified model effect corresponding to the target location node, and meanwhile, the user may be asked whether to confirm that the model at the target location node is modified to the simplified model effect by providing an option.
Step S170, in response to the simplified operation of the simplified control confirmation, deleting the target primitive on the split rigging grid.
In this step, a plurality of target vertices in the target primitive that are shared by other primitives on the split rigging mesh may be determined, where the vertex types of the target vertices include a type corresponding to the target primitive and a type corresponding to the shared primitive, and then other vertices in the target primitive except for the target vertices are deleted, and then the types corresponding to the target primitive in the target vertices are deleted.
In the embodiment of the application, the rigging grid to be adjusted is obtained, the vertex type of the rigging grid to be adjusted is optimized by utilizing the trained grid optimization network to obtain the optimized rigging grid, the optimized rigging grid is subjected to primitive splitting based on the optimized vertex type to obtain the split rigging grid, a graphical user interface comprising the split rigging grid is provided through a terminal device, different primitive difference display is performed, a target primitive corresponding to a target position node on the split rigging grid is determined in response to a specified operation aiming at the target position node on the split rigging grid, a simplified control is displayed aiming at the target primitive in the graphical user interface, the target primitive on the split rigging grid is deleted in response to a confirmed simplified operation aiming at the simplified control, and further redundant primitives which do not participate in stress are deleted after primitive stress participates in analysis, the method and the device realize accurate simplified modification of the rigging grid to be adjusted, can also finish simplified modification of the rigging grid at the node of the target position when a user selects and confirms the simplified modification effect, further realize that the simplified effect after accurate processing is prompted when the user operates and simplifies and modifies the rigging grid, are more convenient for the user to simplify the process of operating the rigging grid, can also flexibly select different simplified results aiming at different position points, improve the operation efficiency of simplifying and modifying the rigging grid, and relieve the technical problem of lower operation efficiency of simplifying and modifying the rigging grid.
The above steps are described in detail below.
In some embodiments, step S170 may specifically include the following steps:
step S1702, determining a plurality of target vertexes shared by the target primitives and other primitives on the split rigging grid, wherein the vertex types of the target vertexes include types corresponding to the target primitives and types corresponding to shared primitives;
step S1704, deleting other vertexes except the target vertex in the target graphic primitive;
step S1706, deletes the type corresponding to the target primitive in the target vertex.
In some embodiments, the method may further comprise the steps of:
and step S180, judging whether each split primitive participates in the stress of the lockset or not, and deleting the redundant primitives which do not participate in the stress from the optimized rigging grid to simplify the control.
In some embodiments, after the step of displaying the simplified control for the target primitive in the graphical user interface, the method may further comprise the steps of:
and step S190, responding to the rejection operation aiming at the simplified control, and hiding the simplified control.
By means of rejection operation aiming at the simplified prompt control, the simplified prompt control can be hidden, and part of the rigging grids at the target position nodes on the rigging grids to be adjusted are kept unchanged, so that simplified modification prompts recommended by a system can be flexibly rejected, and the flexibility of simplified modification is improved.
In some embodiments, the specified operation comprises any one or more of: and aiming at the click operation, the sliding operation and the operation that the touch control time length of the target position node is greater than the preset time length.
Through various operation modes such as click operation, sliding operation, long-time pressing operation and the like, the appointed operation can be more flexible, and the user operation is facilitated.
In some embodiments, the method may further comprise the steps of:
step S200, obtaining a training sample, wherein the training sample comprises an initial lockset grid and a final lockset grid;
step S205, training the initial neural network by using the training sample to obtain a trained grid optimization network; the neural network is used for optimizing the vertex type in the initial rigging grid to obtain the adjusted final rigging grid.
In this regard, one vertex type corresponds to one primitive, and one primitive corresponds to one or more vertex types. The training process of the neural network can be realized through the rigging grid training sample, so that the trained grid simplified network is more accurate, and the rigging grid adjustment process is more efficient and accurate.
The embodiment of the application also provides an adjusting method of the rigging grid, wherein the method can be applied to terminal equipment capable of presenting a graphical user interface, and the method comprises the following steps:
step S210, obtain the rigging grid to be adjusted.
For some rigging grids, modifications and simplifications without affecting the FEA results are needed. For example, in the double-ring buckle model, the pin roll part in the original model file has a single cylinder liner primitive which can be seen through a two-dimensional drawing, while the original model file is opened by software to find that the original model file is a solid cylinder, for example, in the double-ring buckle two-dimensional drawing shown in fig. 2, the connection part between the single cylinder liner primitive and the pin roll before modification is shown as a part in a ring 301 in fig. 3.
Step S220, the trained grid simplified network is utilized to split the pixels of the rigging grid to be adjusted, whether each split pixel participates in the stress of the rigging grid to be adjusted is judged, and the redundant pixels which do not participate in the stress are deleted from the rigging grid to be adjusted so as to simplify the rigging grid to be adjusted, and the simplified first rigging grid is obtained.
The principle of simplification and modification of the rigging grid is that the simplification and modification are simplified without affecting the finite element analysis result (i.e. whether the principle participates in affecting the stress analysis result of the rigging grid to be adjusted). For the understanding of finite element analysis, it is solved by replacing the complex problem with a simpler one. Finite element analysis may consider a solution domain as consisting of many small interconnected subdomains called finite elements, assuming a suitable approximate solution for each element, and then deriving the overall satisfaction conditions (e.g., structural equilibrium conditions) for solving this domain, so that the solution finite element method to solve the problem fundamentally differs from other approximation methods for solving edge-value problems in that its approximation is limited to relatively small sub-domains, finite element methods define functions over the domain of elements of simple geometry (e.g., triangles or arbitrary quadrilaterals in two-dimensional problems) (piecewise functions) and do not consider the complex boundary conditions of the entire definition domain, which is one of the reasons why finite element methods outperform other approximation methods.

It follows that the modification and simplification of the rigging grid is a simplification without affecting the results of the above-described finite element analysis (i.e. without affecting the stresses involved in the rigging grid to be adjusted).
Step S230, providing a graphical user interface including the rigging grid to be adjusted through the terminal device.
Illustratively, the three-dimensional model of the rigging to be adjusted is displayed in a computer screen.
Step S240, in response to the designated operation for the target position node on the rigging grid to be adjusted, determining a simplified portion of the first rigging grid corresponding to the target position node in the first rigging grid.
For example, the user clicks a certain position point on the rigging grid to be adjusted by an operation, and the terminal device searches for a part of the first rigging grid at the position point from the simplified overall first rigging grid, that is, the simplified part of the first rigging grid.
Step S250, displaying a simplified prompt control of a portion of the first rigging grid for the target location node in the graphical user interface.
Illustratively, the simplified part of the first rigging grid is displayed at the target location node by a dotted line, and the dotted line is prompted to indicate the simplified model effect corresponding to the target location node, and the user may be asked by providing an option whether to confirm the modification of the model at the target location node to the simplified model effect.
Step S260, in response to the confirmation operation for the simplified prompt control, adjusting a part of the rigging grid at the target position node on the rigging grid to be adjusted to a part of the first rigging grid.
If the user selects the option of confirming the effect of modifying the model at the target position node into the simplified model, the terminal device adjusts the part of the rigging grid at the target position node on the rigging grid to be adjusted into the simplified part of the first rigging grid.
The trained mesh simplification network is used for splitting the primitives of the rigging mesh to be adjusted, redundant primitives which do not participate in the stress are deleted after the primitive stress participates in the analysis, the accurate simplification modification of the rigging mesh to be adjusted is realized, a user can prompt the effect of the rigging mesh after the simplification modification aiming at a target position node selected by the user when operating the rigging mesh to be adjusted, the rigging grid simplification modification at the target location node can be completed when the user elects to confirm the effect of the simplification modification, and then, the simplified effect after accurate processing is prompted when the user operates the simplified rigging grid to be modified is realized, the process of operating the rigging grid by the user is facilitated to be simplified, different simplified results can be flexibly selected according to different position points, the operating efficiency of simplifying and modifying the rigging grid is improved, and the technical problem of low operating efficiency of simplifying and modifying the rigging grid is solved.
The above steps are described in detail below.
In some embodiments, after step S250, the method may further include the steps of:
