Description

Technical Field

[0001] This application relates to the technical field of model parameters, and particularly to a method for naming parameters of a model for cement industrial equipment. Background Art

[0002] Parametric modeling is a technology for creating and modifying geometric models through parameters and constraints, with multiple advantages.

[0003] First of all, parametric modeling can greatly improve design efficiency and flexibility. By introducing parameters, attributes such as the shape, size, and position of the model can be quickly adjusted. This enables designers to focus on inspiring work such as design and creation, thus achieving the efficient generation of complex designs. This method is not only applicable to simple geometric shapes but can also be used to create complex terrains, sculptures, and industrial equipment, etc.

[0004] Secondly, parametric modeling can also improve the accuracy and reliability of design. Since the elements in the model can be associated with both parameters and other elements. Therefore, when a certain parameter changes, not only the part directly associated with the parameter can change, but other parts in the model can also be automatically adjusted accordingly. This not only improves the flexibility of design but also reduces errors and rework caused by manual modification.

[0005] In addition, the results of parametric modeling can be widely spread through sharing. As long as one person creates a parametric model, others can directly use this model for work, effectively avoiding the repetitive work of modelers and being beneficial to improving the overall work efficiency of the team. Summary of the Invention

[0093] The present application will be further described in conjunction with the accompanying drawings and embodiments. The described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art shall fall within the scope of protection of the embodiments of the present application.

[0094] Although parametric modeling brings many benefits, there are also some problems and challenges. One of them is the naming issue of driving parameters. As the model accuracy increases and the model geometry becomes more complex, the number of parameters to be driven also increases.

[0095] When there is a lack of a unified parameter naming method, it will be difficult to ensure that different modelers give the same parameter names for the same driving actions. This not only means that the parameter names of parametric models lack a unified standard. More importantly, it may make it difficult for model users to accurately understand the intentions of modelers. Each model user needs to spend additional time costs to communicate face-to-face with modelers in order to understand the meanings of the parameters in the parametric model. Even for modelers themselves, when facing complex models and lacking a unified parameter naming method, they may forget the specific meanings represented by some parameters after a period of time. As a result, the advantages of high efficiency and convenience of parametric models are lost, excellent modeling results are difficult to be smoothly promoted and applied, and the accumulated digital assets are difficult to play their maximum utility.

[0096] For example, for a cuboid, as Figure 2 shown. Its own driving parameters of the geometry are length, width, and height. When the length is shorter than the width, the modeler may define the length as the direction corresponding to the longer side, or may define the length as the direction of horizontal extension. When the geometry is relatively simple and the number of driving parameters is small, the ambiguity of the above parameter names will not have too much impact on the use of the parametric model. However, when the geometry becomes complex, this semantic ambiguity of the parameters will directly make the parametric model difficult to use. For the parametric model of cement industry equipment, the number of its driving parameters can be up to 50. If there is semantic ambiguity at this time, it will directly affect the normal use and rapid promotion of the parametric model.

[0097] At the same time, due to the complexity of the geometry of parametric equipment models and their geometric components, when there is a lack of means for simplified analysis, it is itself a difficult thing to uniformly name the driving parameters. For example, as Figure 3 shown, for a parametric equipment model, it is composed of multiple component geometries. Each component not only contains functional geometries but also contains many constructive or decorative geometries. At the same time, there are also relative relationships to be driven between components. If simplified analysis is not carried out and the parametric relationships of the geometries are directly established. Then in the face of so many parameters, the number of parameters that may cause ambiguity will be several times that of a cuboid. More challenging is that when the specific meaning represented by the parameter positioning is lacking, the description of special geometric parameters will become complex and difficult. For example, it is necessary to drive Figure 3In [the text], the distance between the gas storage tank and the box body. Then, is this distance the distance of the gas storage tank relative to the center of the box body, or relative to the left surface of the box body, or relative to the front of the box body? In addition, for the gas storage tank, is it the distance relative to the center of the gas storage tank, or relative to the right support of the gas storage tank, or relative to the front of the support of the gas storage tank? Thus, it can be seen that if there is a lack of a unified parameter naming format, the parameter naming results will surely be chaotic.

[0098] Therefore, establishing a unified and applicable parameter naming method is essential for the parametric model of cement industry equipment.

[0099] To solve the problems existing in the naming process of the parametric model, this application provides an embodiment of a parameter naming method for the model of cement industry equipment. First, components and their names are defined. Then, by defining the approximation principle of the component form, the change methods of the component form are uniformly specified, and the specific steps for the simplified analysis of the component form are given, realizing the simplified analysis of complex forms. Subsequently, based on the simplified form, a space coordinate system of the cement industry equipment model (abbreviation: model) and the local coordinate system of the component itself are established. Furthermore, the specific meanings represented by the relative positioning name and the driving positioning name are defined, avoiding the semantic ambiguity of ordinary parameter names. Finally, based on the above relative positioning name, driving positioning name, and component name, the name formats of the component space positioning parameters, component geometric form parameters, and component visibility parameters are defined. Ultimately, the parameter naming method for the parametric model of cement industry equipment is realized.

[0100] See Figure 1 , the technical solution of the embodiment of this application includes:

[0101] S1. Determine the component form name. Among them, the component is a constituent unit of the model (cement industry equipment model).

[0102] If the component is the main body of the equipment, the name of this component is the name of the equipment;

[0103] If the component is a part of the equipment, the name of this component is the name of the part;

[0104] If the component is a fitting of the equipment, the name of this component is the name of the fitting;

[0105] If the component is a part of the equipment, the name of this component is the name of the part;

[0106] If the component is driven as a whole, such as Figure 3 the gas storage tank and its support in [the text], then the name of the whole component is the name of the functional component in this component.

[0107] If the component is a sub-component of a certain component, the name format of the component is "parent component name_sub-component name". The two are connected by an English underscore "_". If the parent component is the main body of the device, then the " parent component name_ ” is omitted; where the component is a constituent unit of the cement industry equipment model.

[0108] S2. Determine the approximate shape of the component body.

[0109] S21. Define the approximate shape of the component body as: a cuboid, or its variant (a shape obtained by changing based on the cuboid), a cylinder, or its variant (a shape obtained by changing based on the cylinder).

[0110] S22. Defining the approximation as a cuboid or its variant means that the component body can be wrapped with a cuboid or its variant. The specific wrapping steps include S221 to S224:

[0111] S221. Remove local protrusions or depressions in the component body.

[0112] S222. Remove the accessory parts in the component body. The accessory parts are the parts that do not require direct parameter drive and the decorative parts.

[0113] S223. The remaining part of the body can be wrapped with a cuboid or its variant, and the number of wrapping surfaces accounts for more than 66% of the total number of surfaces of the cuboid or its variant. Note that the wrapping surface mentioned here refers to a certain surface of the shape that can partially or completely occupy the surface of the cuboid or its variant. For example, a cuboid can be used to wrap an I-beam, and the upper and lower surfaces of the I-beam, as well as the two end surfaces, can be wrapped by the top and bottom surfaces, and the left and right surfaces of the cuboid, as Figure 4 shown.

[0114] S224. Define the change steps of the cuboid variant to include S2241 to S2243:
