Description

Technical Field

[0001] This invention relates to a method for processing pattern information of acoustic flexible structures, and also to a storage medium for pattern information of acoustic flexible structures. Background Technology

[0002] Noise-reducing acoustic packages are important components in transportation vehicles such as locomotives, airplanes, and ships. These packages, including sound insulation layers, insulating films, and foam components, are typically located between the cabin structure and the interior materials and equipment, serving functions such as heat insulation, noise isolation, and flame retardancy. The noise-reducing acoustic package itself is often a soft, multi-layered textile component. During manufacturing, the component is a flat, two-dimensional structure; after installation, it adheres to a rigid structure, resulting in a three-dimensional installation.

[0003] Traditional acoustic package design is based on two-dimensional drawings, which makes it difficult to unify and coordinate the three major design elements: configuration management, manufacturing drawings, and installation drawings. It largely relies on designers to manually measure and quantify between three-dimensional digital prototypes, two-dimensional manufacturing states, and actual installation states. This limits the design and production efficiency of flexible structures and materials such as acoustic packages. While consuming a lot of manual design time, it also implies the drawback of asymmetry between configuration, manufacturing, and installation design, becoming a major technical bottleneck for flexible structures and materials in terms of drawing information and storage. Summary of the Invention

[0004] The purpose of this invention is to provide a method and storage medium for processing graphic information of acoustic flexible structures, which solves the problem of how to unify and coordinate the three major design elements of configuration management, manufacturing drawings, and installation drawings.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a method for processing graphic information of acoustic flexible structures. It includes placing a three-dimensional solid model, a two-dimensional geometric set for production, and installation point information in the same geometric model, so that at least three parameters of installation point position, boundary size, and material information are linked. The unfolded size of the three-dimensional solid model and the boundary size of the two-dimensional geometric set for production are related through a set magnification factor. The information expressed in the three-dimensional solid model includes the three-dimensional solid structure, the planar unfolded state, and engineering annotations including manufacturing process specifications, installation process specifications, and management process specifications. The two-dimensional geometric set for production includes the unfolded state of components, the unfolded state of the core, the selection elements of interlayer materials, the elements of component installation method, and annotation information. The installation point information includes the installation position information of fasteners.

[0006] Preferably, it further includes obtaining design compliance inspection information, obtaining product geometric dimension compliance review information based on the geometric dimensions of the component unfolded state, obtaining material selection design compliance review information based on the interlayer material of the component, and obtaining weight design compliance review information based on the statistical values ​​of the component unfolded state in the drawing.

[0007] Preferably, spatial station information is introduced into the three-dimensional solid model to reflect the spatial coordination of the interference structure and system.

[0008] Preferably, the magnification factor between the unfolded dimensions of the three-dimensional solid model and the boundary dimensions of the two-dimensional geometry set used for production is adaptively adjusted according to the production process, installation method, and materials.

[0009] Furthermore, the magnification factor is 1.03~1.05.

[0010] Preferably, the three-dimensional solid model includes thermal and sound insulation layer components, which include core material, covering layer, tape, fasteners, and stitching information, and a separate geometry set is established for each material information.

[0011] Preferably, the two-dimensional geometry set for production includes the component unfolded state, the core unfolded state, the interlayer material selection elements, and the component installation method elements, wherein the component unfolded state includes the geometric dimensions of the heat insulation and sound insulation layer covering layer, glass wool core, installation holes and cuts, and seam elements.

[0012] Preferably, the installation point information also includes fastener instance representations, showing the installation status of the 3D solid model and the fasteners.

[0013] A pattern information storage medium for an acoustic flexible structure is also provided, on which a computer program is stored, which, when executed by a processor, implements the pattern information processing method for any of the aforementioned acoustic flexible structures.

[0014] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art: The present invention provides a method and storage medium for processing pattern information of acoustic flexible structures, defining a full three-dimensional pattern information and storage medium for acoustic flexible structures and materials, defining a three-dimensional solid model, installation points and a two-dimensional geometric set for production, and placing them in the same geometric model, thereby realizing full three-dimensional configuration management of the model and directly using it for production and installation.

Detailed Implementation

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1 As shown, the acoustic flexible structure pattern information processing method of the present invention places the three-dimensional solid model, the two-dimensional geometry set for production, and the installation point information in the same geometric model. Furthermore, some parameters among the three are related, thereby ensuring consistency from design (three-dimensional solid model), production (two-dimensional geometry set for production), to installation (installation point information). The acoustic flexible structure is a heat and sound insulation layer.

[0020] The 3D solid model drawings include: assemblies defining the heat and sound insulation layers according to the machine body's laying area; a single sound insulation layer component defined as a part; the planar unfolded state of a single heat and sound insulation layer; the planar unfolded state of the core of a single heat and sound insulation layer; and the planar unfolded state of the core of a single heat and sound insulation layer. The machine body laying area can be determined according to the machine body's structure or based on the machine body's noise analysis.

[0021] The graphic components of a 3D solid model can include: the solid model, the unfolded planar state, engineering annotations, material information, and a set of annotations. The solid model is generated or drawn based on the 3D structure of the organism and can be used for spatial coordination of interference structures and systems, as well as for calculating the geometric center, center of mass, and volume. It can also be used for weight calculation (after writing the material information).

[0022] The 3D solid model also includes engineering annotations, which reference the manufacturing process specifications, installation process specifications, and management process specifications for the thermal insulation and sound insulation layer.

[0023] Information on all materials required for the thermal and sound insulation layer components, including core materials, covering layers, tapes, fasteners, and stitching, is used to establish separate geometric sets in the "Material Information" geometric set, named "Material 1", "Material 2", "Material 3", and so on.

[0024] Based on the production process of the thermal and sound insulation layer, a secondary geometry set is created in the digital model, using a 1:1 scale production-grade 2D geometry set. This production-grade 2D geometry set is primarily used for producing the core and covering layers of the thermal and sound insulation layer, providing drawings for production. The production-grade 2D geometry set mainly includes: a) Component unfolded state: containing the geometric dimensions of the covering layer, glass wool core, mounting holes and cuts, seams, etc.; b) Core unfolded state: containing the geometric dimensions of the glass wool core within the thermal and sound insulation layer; c) Interlayer material selection: containing the material selection elements for the covering layer and glass wool core of the thermal and sound insulation layer; d) Installation method or installation diagram: containing the component installation method elements. The production-grade 2D geometry set contains various production drawing information, mainly including: component unfolded state, core unfolded state, interlayer material selection, and installation method or installation diagram, as well as the physical assembly state. The component unfolded state is used to express the cutting of the thermal and sound insulation layer covering layer, the positioning of mounting holes, cuts, and seams, and the unfolding of the component after forming. The core unfolded state is used to show the cutting pattern information of the glass wool core inside the thermal and sound insulation layer. The installation method or installation diagram is used to show the installation method at the fixed positions between components and between components and the body structure. The physical installation state is used to show the installation pattern information of the thermal and sound insulation layer on the body structure.

[0025] The installation point information is generated by constructing a geometric set in the digital model based on the installation position of the thermal and sound insulation layer on the machine. The positions of the fasteners are marked using points, lines, and surfaces. Furthermore, the fasteners are instantiated using a "full three-dimensional representation of fasteners," displaying the installation status of the thermal and sound insulation layer and its fasteners, thus providing more intuitive guidance for fastener installation.

[0026] There is a certain correlation between the three main geometric sets mentioned above—the three-dimensional solid model, the two-dimensional geometric set for production, and the installation point information. This ensures that changing some parameters in one set will change the corresponding parameters in the others, thus guaranteeing consistency from design and production to installation. Specifically, the unfolded dimensions of the three-dimensional solid model are correlated with the boundary dimensions of the two-dimensional geometric set for production through a certain magnification factor. This is because the present invention is applied to acoustically flexible structures, namely thermal and sound insulation layers, which have a certain degree of compressibility and will shrink in size during production or installation. Therefore, to ensure that the dimensions of the produced planar thermal and sound insulation layer still match the surface of the machine body after being covered, the planar dimensions are magnified to a certain extent during the production of the thermal and sound insulation layer. The magnification factor is generally 1.03~1.05, and in special cases, it can reach 1.1, but generally will not exceed 1.1. The magnification factor is related to the way the thermal and sound insulation layer is covered on the machine body, such as external or internal covering. It is also related to the manufacturing process of the thermal and sound insulation layer. For example, the shrinkage of the material may vary under different manufacturing processes. It is also related to the thickness and material of the material. For example, if the material is thicker, the magnification factor will be appropriately increased.

[0027] The drawing information processing method of the present invention further includes obtaining design compliance check information, which can be obtained based on existing information. This includes reviewing the product's geometric dimensions, material selection, and weight for design compliance. The product's geometric dimensions are reviewed based on the geometric dimensions of the component in its unfolded state. The material selection is reviewed based on the interlayer materials of the component. The weight is reviewed based on the statistical values ​​of the component in its unfolded state as shown in the drawing.

[0028] like Figure 2 As shown, the 3D solid model, the 2D geometry set for production, and the installation point information are all housed within a single geometric model. Furthermore, the parameters of these three elements—installation point location, boundary dimensions, and material information—are interconnected. For example, modifying the dimensions of the 3D solid model will automatically change the boundary dimensions of the 2D geometry set for production. Similarly, modifying the installation point location information will adaptively update the drawings of the 3D solid model, the 2D geometry set for production, and the installation point location. This ensures consistency from design and production to installation.

[0029] The present invention also relates to a storage medium storing a computer program that, when executed by a processor, constructs the aforementioned pattern information.

[0030] In this invention, a two-dimensional and three-dimensional consistent method and storage medium for processing graphic information of acoustic flexible structures are adopted to solve the following problems in graphic expression, thereby improving the information integration and consistency of flexible structure and material design, production and installation.

[0031] (1) Integrate the three-dimensional entity, two-dimensional information, process annotations and installation position requirements of flexible structures and materials into a single drawing or digital model; (2) Output the flexible structure and material components and the unfolded state of the core in layers, and use the unfolded state of the core for cutting, production and processing; (3) To realize the simultaneous construction and storage of two-dimensional unfolding information and three-dimensional installation information of flexible structure and material under one drawing information, so as to ensure consistency from design, production to installation.

[0032] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
