[0022] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0023] In the related art, common 3D modeling software, such as SolidWorks, ABAQUS, CATIA or Creo, only supports conventional simulation functions. There are also some advanced simulation software that can provide more comprehensive physical factor integration functions, but they are highly complex, expensive, and difficult to integrate into existing design processes.

[0024] Therefore, it is urgent to develop an enhanced module that can be seamlessly integrated into existing 3D modeling software to dynamically integrate the above physical factors in motion simulation, thereby providing a more accurate and practical simulation solution. This can not only improve the efficiency of the design phase, but also reduce development costs and shorten product time to market, which has important industrial application value.

[0025] In order to solve the above technical problems, an embodiment of the present invention provides a three-dimensional model motion simulation data processing method based on three-dimensional modeling software. Figure 1 The invention is a method for processing 3D model motion simulation data based on 3D modeling software, such as Figure 1 As shown, the method comprises the following steps:

[0026] Step S101, in response to the action of starting the 3D modeling software, loading the simulation enhancement module and initializing it, wherein the simulation enhancement module is a functional plug-in pre-created in the 3D modeling software using a development tool, and the simulation enhancement module is connected to the 3D modeling software through an application program interface;

[0027] Step S102, acquiring and importing a corresponding target three-dimensional model according to simulation requirements;

[0028] Step S103, in response to the input operation of the simulation configuration parameters, calling the parameter configuration interface of the simulation enhancement module, and receiving the input simulation configuration parameters through the parameter configuration interface;

[0029] Step S104, calculating simulation parameters in the simulation process using the mathematical model of the simulation enhancement module according to the simulation configuration parameters;

[0030] Step S105 , generating a simulation report from the simulation parameters, and visualizing it on the target three-dimensional model through a visualization tool.

[0031] The above-mentioned three-dimensional model motion simulation data processing method based on three-dimensional modeling software provided by the embodiment created by the present invention creates a simulation enhancement module through the development tool of the three-dimensional modeling software, and is connected to the simulation enhancement module through an application program interface. When in use, the data of the target three-dimensional model is directly obtained from the three-dimensional modeling software according to the simulation requirements, simulation calculations are performed, and corresponding simulation results are output, thereby realizing the configuration of the simulation mathematical model of the target three-dimensional model according to the requirements, thereby improving the simulation accuracy of the target three-dimensional model.

[0032] The execution subject of the above steps can be a computer or server running the 3D modeling software. It should be noted that the above simulation enhancement module is configured on the 3D modeling software and used in conjunction with the 3D modeling software. Therefore, the subject running the above 3D modeling software is also the subject running the simulation enhancement module.

[0033] The above-mentioned 3D modeling software may be common 3D modeling software such as SolidWorks, CATIA or Creo, etc. Generally, the accompanying simulation analysis often fails to fully integrate physical factors for simulation, and there is a problem of insufficient simulation accuracy.

[0034] The simulation enhancement module can be a functional plug-in created through a development platform based on the 3D modeling software. When in use, in response to the action of starting the 3D modeling software, the simulation enhancement module is loaded and initialized. Initialization includes confirming the compatibility of the software environment and loading basic data files to prepare for subsequent use.

[0035] Then, the corresponding target three-dimensional model is obtained and imported according to the simulation requirements. The target three-dimensional model can be a file imported by the three-dimensional modeling software. It can also be a three-dimensional model created based on the function of the three-dimensional modeling software. The simulation requirements can characterize the target three-dimensional model that needs to be simulated and the content that needs to be simulated.

[0036] For example, taking a five-axis machine tool as an example, the simulation requirement may be to simulate the machining process of the five-axis machine tool. The corresponding target 3D model is also the 3D model of the five-axis machine tool, and the simulation content is also the machining motion simulation of the five-axis machine tool.

[0037] When performing simulation calculations, it is necessary to rely on the physical parameters of different parts of the 3D model. These physical parameters can be set when the 3D model is created, or they can be defined during simulation. These physical parameters include material properties, strength, hardness, surface roughness, friction, friction coefficient, etc., which are used to characterize the physical parameters of the real hardware corresponding to the 3D model.

[0038] In this way, the simulation algorithm can be used to calculate and obtain the corresponding simulation parameters, including deformation at different positions, force and movement of different parts, etc.

[0039] When using the simulation enhancement module, in response to the input operation of the simulation configuration parameters, the parameter configuration interface of the simulation enhancement module is called. The user inputs the simulation configuration parameters through the parameter configuration interface, and the execution subject receives the input simulation configuration parameters.

[0040] Then, according to the simulation configuration parameters, the mathematical model of the simulation enhancement module is used to calculate the simulation parameters during the simulation process. The above mathematical model is also the mathematical model of the physical quantity actually used for simulation calculation. The mathematical model is created when the simulation enhancement module is created.

[0041] The simulation content and calculation results of each mathematical model are different. The simulation result data after the corresponding simulation movement can be calculated according to several known simulation configuration parameters. For example, the friction model can calculate the movement of the target part according to the friction coefficient and force of the target part.

[0042] After obtaining the simulation parameters after simulation, the simulation parameters are generated into a simulation report, and visualized on the target three-dimensional model through visualization tools. For example, charts, animations, etc. can intuitively show the simulation results.

[0043] As an optional embodiment, the simulation parameters in the simulation process are calculated according to the simulation configuration parameters using the mathematical model of the simulation enhancement module, and the method also includes: verifying the integrity and format of the simulation configuration parameters, and if the verification is passed, converting the simulation configuration parameters into a structured form required for calculation; calling a path planning model according to the structured simulation configuration parameters to calculate the initial motion path, wherein the mathematical model includes the path planning model; correcting the simulation configuration parameters according to actual motion conditions, and optimizing and adjusting the initial motion path according to the corrected simulation configuration parameters to obtain an optimized motion path; and performing simulation according to the optimized motion path to obtain simulation parameters in the simulation process.

[0044] Since different simulation configuration parameters have different formats and value ranges, after entering the simulation configuration parameters, integrity verification and format verification can be performed on the simulation configuration parameters. If the verification fails, the user is prompted to modify or provide the corresponding simulation configuration parameters again until the verification passes.

[0045] If the verification is passed, it means that there is no problem with the simulation configuration parameters, and the simulation configuration parameters need to be converted into the structured form required for calculation. This is to unify the data format with the 3D simulation software to facilitate subsequent simulation calculations, data storage and display.

[0046] The above path planning model calculates the motion path of each component according to the simulation configuration parameters. Specifically, according to the structured simulation configuration parameters, the path planning model is called to calculate the initial motion path.

[0047] In order to improve the accuracy of the motion path, the simulation configuration parameters are corrected according to the actual motion conditions, and the initial motion path is optimized and adjusted according to the corrected simulation configuration parameters to obtain the motion optimized path.

[0048] Then, simulation is performed based on a more accurate motion optimization path to obtain more accurate simulation parameters during the simulation process, thereby improving the accuracy of the simulation parameters.

[0049] As an optional embodiment, after calculating the simulation parameters in the simulation process using the mathematical model of the simulation enhancement module according to the simulation configuration parameters, it also includes: obtaining standard parameters, calculating the simulation error according to the simulation parameters and the standard parameters; optimizing the motion optimization path according to the simulation error to obtain the target motion path; simulating according to the target motion path to obtain corrected simulation parameters.

[0050] After the simulation parameters are calculated, the standard parameters can also be obtained, and the simulation errors can be calculated according to the simulation parameters and the standard parameters to determine the simulation accuracy and truth rate of the simulation parameters.

[0051] According to the simulation error, the motion optimization path can be further optimized to obtain a more accurate target motion path than the motion optimization path. Then, simulation is performed according to the more accurate target motion path to obtain more accurate simulation parameters after correction.

[0052] The above-mentioned standard parameters may be standard data obtained from actual experiments, and the simulation parameters may be corrected by the standard data to optimize the corresponding mathematical model and improve the accuracy of the simulation parameters.

[0053] It should be noted that the above method can be used as a correction step in the case of regular correction or correction according to demand.

[0054] As an optional embodiment, the method further includes: pausing the simulation and adjusting corresponding simulation configuration parameters according to adjustment requirements; performing motion simulation according to the adjusted simulation configuration parameters to obtain adjusted simulation parameters.

[0055] When using the simulation enhancement module, there may be a need to modify the simulation configuration parameters. For example, in some scenarios such as selecting the optimal parameters through trial and error, it is hoped that the simulation configuration parameters can be adjusted according to the needs.

[0056] If adjustments are needed, the adjustment requirements can be triggered through the simulation enhancement module or the 3D modeling software. The simulation is paused according to the adjustment requirements, and the simulation configuration parameters are updated.

[0057] According to the adjusted simulation configuration parameters, motion simulation is performed to obtain adjusted simulation parameters, thereby meeting more practical needs.

[0058] As an optional embodiment, in response to the action of starting the three-dimensional modeling software, loading the simulation enhancement module, and before initializing, the method also includes: building a development platform based on the three-dimensional modeling software, and configuring an application program interface; through the development platform, creating a corresponding mathematical model according to the physical factors in the simulation process to build the simulation enhancement module; connecting the simulation enhancement module with the three-dimensional modeling software through the application program interface to enable the simulation enhancement module to communicate data with the three-dimensional modeling software; creating an interactive page based on the simulation enhancement module, wherein the interactive page is used for users to input or select relevant parameters; and testing and debugging the simulation enhancement module.

[0059] When building the above simulation enhancement module, first build a development platform based on the 3D modeling software and configure the application program interface. The above development platform is generally matched with the 3D modeling software and can be obtained from the product side of the 3D modeling software. The development platform can be used to expand the functions of the 3D modeling software through programming.

[0060] The above-mentioned application program interface API is used to generate data interaction with the 3D modeling software, including obtaining required data and outputting data.

[0061] Through the development platform, according to the physical factors in the simulation process, the corresponding mathematical model is created as the core algorithm to build the simulation enhancement module. Different mathematical models are used to calculate the required simulation data according to different input data. The details will be explained later.

[0062] The simulation enhancement module is connected to the 3D modeling software through the application program interface so that the simulation enhancement module and the 3D modeling software can communicate data, thereby performing more accurate and detailed simulation enhancement according to the parameters of the target 3D model.

[0063] Based on the simulation enhancement module, an interactive page is created, through which the system can interact with users. Users can input or select relevant parameters through the interactive interface, and the interactive interface can display simulation results to users through charts and other means.

[0064] After the simulation enhancement module is built, it can be tested and debugged. This includes testing and debugging of each functional module, as well as overall testing and debugging. After the test is passed, it can be used to ensure the simulation accuracy of the simulation enhancement module.

[0065] As an optional embodiment, a development platform is built based on three-dimensional modeling software, and an application program interface is configured, including: downloading and installing the development platform and application program interface of the three-dimensional modeling software, and a programming language environment that supports the development platform and application program interface; configuring the auxiliary library required for the simulation of the target three-dimensional model, wherein the auxiliary library includes at least one of the following: a dynamic calculation library, a path optimization algorithm library; configuring the path and dependencies of the development platform, and setting modular compilation options related to the simulation of the target three-dimensional model; creating a test project for module debugging of the target three-dimensional model, and loading the processing path and workpiece model of the target three-dimensional model.

[0066] When building a development platform and configuring the application program interface, first download and install the development platform and application program interface of the 3D modeling software, as well as the programming language environment that supports the development platform and application program interface. This can be achieved through the application program interface development platform. For example, the application program interface API development platform can be SolidWorks API, CATIA CAAAPI, etc., which can be obtained from the product side of the corresponding 3D modeling software. The above-mentioned programming language environments, such as C++, Python or C#, can be obtained through their respective suppliers.

[0067] It also includes auxiliary libraries required for configuring the target three-dimensional model simulation, and the auxiliary libraries include at least one of the following: a dynamics calculation library, a path optimization algorithm library; and are used to provide the calculation method or mathematical model required for the simulation.

[0068] Then configure the path and dependencies of the development platform, and set the modular compilation options related to the simulation of the target 3D model, so that the target 3D model can be guided to perform simulation motion according to the motion path.

[0069] Create a test project for module debugging of the target 3D model, and load the processing path and workpiece model of the target 3D model, so as to debug and test the simulation enhancement module later.

[0070] As an optional embodiment, the mathematical model includes at least one of the following: a friction model, an assembly error model, and a weight factor model; through the development platform, a corresponding mathematical model is created according to the physical factors in the simulation process to build a simulation enhancement module, including: based on the Coulomb friction model, the friction force under different conditions is calculated, and the influence on the movement of the target three-dimensional model is simulated according to the friction force, wherein the friction force includes dynamic friction and static friction; and / or, based on the Gaussian distribution, the error range and standard deviation of the assembly error at different positions are calculated, and the error range and standard deviation are applied to the corresponding position to dynamically simulate the influence of the assembly error on the movement path; and / or, according to the mass and position of each component of the target three-dimensional model, the center of gravity distribution is calculated, and the force application point of each component is determined during the simulation according to the center of gravity distribution.

[0071] The above Coulomb friction model can be combined with the characteristics of the rotating axis and slide rail of the five-axis machining equipment to dynamically calculate the friction force F friction =μ⋅F normal , where F friction is the actual friction force, μ is the friction coefficient, F normal is the normal force acting on the contact surface.

[0072] Dynamic friction is the friction force that changes with the speed of movement. It is suitable for the simulation of rotating bearings in five-axis machine tool processing. Static friction is suitable for the initial motion analysis when the five-axis machine tool processing starts, taking into account the roughness of the contact surface.

[0073] The assembly error model generates the assembly errors of different components of the five-axis machine tool based on Gaussian distribution, and defines the error range and standard deviation of the rotary axis and linear axis; then the numerical value of the assembly error is applied to the starting position of each axis, and the influence of each axis on the machining path under the corresponding assembly error is dynamically simulated.

[0074] The weight factor model is to calculate the weight of each component in the five-axis machine tool by the following formula: W = m⋅g, where W is the weight, m ​​is the mass of the component, and g is the acceleration of gravity;

[0075] The mass and position of each component are summarized to calculate the center of gravity distribution of the entire five-axis machine tool system; during the simulation process, the weight is applied to the center of gravity of the component.

[0076] As an optional embodiment, a corresponding mathematical model is created through a development platform according to physical factors in the simulation process to build a simulation enhancement module, including: creating a data input module and connecting it to the three-dimensional modeling software through an application program interface, so as to automatically obtain the geometric parameters of the target three-dimensional model from the three-dimensional modeling software according to needs; creating a physical calculation module, incorporating the mathematical model into the physical calculation module for calling, and connecting it to the data input module; creating a simulation result display module, connecting it to the physical calculation module, and obtaining simulation parameters according to needs.

[0077] When building the simulation enhancement module, modular design is carried out. According to different functions, the simulation enhancement module is divided into data input module, physical calculation module, and simulation result display module. Each module has corresponding functions and can be programmed separately during programming, thereby improving the construction efficiency and facilitating subsequent maintenance and updates.

[0078] It should be noted that this embodiment also provides an optional implementation, which is described in detail below.

[0079] The purpose of this embodiment is to provide a mechanical motion simulation enhancement module based on 3D modeling software.
