Description

一种基于CATIA的航空制动紧固件库的建立方法A CATIA-Based Establishment Method of Aviation Brake Fastener Library

技术领域 technical field

本发明属于参数化建模领域,尤其涉及一种基于CATIA的航空制动紧固件库的建立方法。 The invention belongs to the field of parametric modeling, in particular to a method for establishing a CATIA-based aviation brake fastener library.

背景技术 Background technique

在机械产品中,有30%-70%的零件是标准件或非标准常用件,这些零件结构相似但尺寸不同,在产品设计和开发过程中,零部件的标准化、系列化、通用化成为提高产品设计质量、缩短产品开发周期的有效途径。因此广泛应用标准件,即研制标准件库能够为产品设计带来便利。在航空制动结构的设计与制造过程中,标准件的种类非常多,其中螺纹紧固件的使用数量占总零件的30%~40%。因此在设计过程中合理地应用标准件,尤其是螺纹紧固件,可以简化结构设计,提高装配效率,对缩短产品设计制造周期、降低生产成本、提高产品质量都具有十分重要的技术经济意义。 In mechanical products, 30%-70% of the parts are standard parts or non-standard common parts. These parts are similar in structure but different in size. An effective way to improve product design quality and shorten the product development cycle. Therefore, the wide application of standard parts, that is, the development of standard parts library can bring convenience to product design. In the design and manufacture of aerospace brake structures, there are many types of standard parts, among which the number of threaded fasteners used accounts for 30% to 40% of the total parts. Therefore, the rational application of standard parts, especially threaded fasteners, in the design process can simplify structural design and improve assembly efficiency, which has very important technical and economic significance for shortening product design and manufacturing cycles, reducing production costs, and improving product quality.

近年来,特别是进入20世纪90年代以来,数字化技术在全世界制造企业,尤其是在大型飞机制造企业中的地位越来越得到重视,己经成为一个能否战胜同等地位企业的重要标志。数字化研制是一场由里到外、由旧到新的全新生产方式的变革,它推动着管理体制、组织体系、标准规范、设计方法、生产运作、思维方式及工作方式的根本改变。 In recent years, especially since the 1990s, the status of digital technology in manufacturing companies around the world, especially in large aircraft manufacturing companies, has been paid more and more attention, and it has become an important symbol of whether they can beat companies with the same status. Digital R&D is a transformation of a new production method from the inside to the outside, from the old to the new. It promotes fundamental changes in management systems, organizational systems, standards, design methods, production operations, ways of thinking and ways of working.

MBD技术是CAD技术发展的新趋势,己经在飞机设计制造中得到应用。飞机的设计制造要求使用三维实体模型作为生产制造过程中的唯一依据,采用MBD模型后,三维模型将贯穿于设计、工装、工艺、制造和装配等生产的各个环节。但是有很多零件在结构上都有相似性,所以在建立MBD模型时需要去做重复的工作,这将浪费大量的时间,降低开发的效率,延长新产品的开发周期。 MBD technology is a new trend in the development of CAD technology, and has been applied in aircraft design and manufacture. The design and manufacture of aircraft requires the use of a three-dimensional solid model as the only basis in the manufacturing process. After the MBD model is adopted, the three-dimensional model will run through all aspects of production such as design, tooling, process, manufacturing and assembly. However, there are many parts that are similar in structure, so it is necessary to do repetitive work when building the MBD model, which will waste a lot of time, reduce the efficiency of development, and prolong the development cycle of new products.

以半圆头螺栓为例,首先在“公式”中建立决定螺栓形状的特征参数,然后建立半圆头螺栓的三维模型模板,并用特征参数对其草图进行完全约束,最后利用“设计表”功能添加先前整理好的参数表,使其与模型相关联,实现零件的系列化。 Taking the round head bolt as an example, first establish the characteristic parameters that determine the shape of the bolt in the "formula", then establish the 3D model template of the round head bolt, and use the characteristic parameters to fully constrain its sketch, and finally use the "design table" function to add the previous Organize the parameter table and associate it with the model to realize the serialization of parts.

在CATIA中新建“Catalog”文件,通过“添加零件系列”选择已经建立好的模型文件,考虑到后期装配过程中可能暂时不会用到零件的尺寸信息,故MBD定义完成后将标注集信息暂时隐藏,在调用时如需零件的尺寸信息可在模型树中显示标注集信息。 Create a new "Catalog" file in CATIA, and select the model file that has been established through "Add Part Series". Considering that the size information of the part may not be used temporarily in the later assembly process, the label set information will be temporarily added after the MBD definition is completed. Hidden, if you need the size information of the part when you call it, you can display the annotation set information in the model tree.

在进行装配设计过程中,通过“工具”菜单中的“目录浏览器”命令,在对话框中打开建好的HBStandards零件库文件,即可在目录浏览器窗口浏览零件库中的零件。在图形目录列表中选取相应规格的零件,双击即可生成对应的零件,并加入到当前的装配体中。 In the process of assembly design, through the "Catalogue Browser" command in the "Tools" menu, open the built HBStandards parts library file in the dialog box, and then browse the parts in the parts library in the directory browser window. Select the part of the corresponding specification in the graphic catalog list, double-click to generate the corresponding part, and add it to the current assembly.
