Problems solved by technology

Although it is possible to unify the grades of these different types of corner profiles in the most complicated form, make an Excel table for multi-parameter sorting, and then perform matching, it still cannot reduce the repetitive workload of designers

Abstract

The invention discloses an extruded profile mark screening method. The method comprises the following steps of: establishing a database and grouping extruded profile sections according to different extruded profile section shapes; selecting a corresponding extruded profile section group for a to-be-manufactured part; obtaining a section parameter of the to-be-manufactured part; setting a preset condition without considering through-connection corner radii; selecting the through-connection corner radii, calculating theoretical maximum through-connection corner radii and screening a theoretical maximum through-connection corner radius which is smaller than a through-connection corner radius of the to-be-manufactured part; and after an extruded profile mark which accords with the section parameter is obtained, selecting the extruded profile mark to use. According to the method disclosed by the invention, optimum extruded profile marks can be selected for extruded profile-manufactured parts, and proper marks can be selected during the lack of corresponding marks.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and in particular relates to a method for screening grades of extrusion profiles. Background technique [0002] There are a large number of parts made of extruded profiles on the aircraft. At present, designers need to consult the extruded profile manual when selecting the grade of extruded profiles for these parts. The repetitive workload is relatively large, time-consuming and laborious. [0003] Such as figure 1 As shown, the commonly used extruded profiles are divided into: angle profiles, T profiles, channel profiles, Z profiles and I profiles according to their cross-sectional shapes. For example, the commonly used specifications of angle profiles are first divided into right-angle profiles, acute-angle profiles and obtuse-angle profiles in the extrusion profile manual according to the angle between the two sides, and right-angle profiles can be divided into equilateral profiles ac...
