Optimized design method of airplane process equipment

Abstract

The invention discloses an optimized design method of airplane process equipment. Under the premise that fixture strength requirements are met, strain analysis is performed on a fixture of the process equipment, structural size is optimized, failing of a positioning function of the process equipment due to the fact that the fixture is insufficient in strength and wasting of a material due to the fact that the fixture is excessive in strength are avoided, weight after weight reducing is reduced by at least one tenth when compared with that of a conventional design method; in a three-dimensional math model, processing areas different in accuracy level are marked by colors, the math model together with a drawing is used during numerical-control processing and three-dimensional coordinate detection, processing accuracy requirements can be determined more visually, processing time can be reduced, and manufacturing and detection cost can be saved.

Description

technical field [0001] The invention relates to an optimal design method related to the design of aircraft technology equipment. Background technique [0002] In the traditional aircraft assembly process equipment, there are a large number of aircraft parts to be assembled, high positioning accuracy requirements for process equipment, strict coordination dimensions, and a large number of riveting work. Therefore, the size of the frame is often determined based on experience, resulting in The frame is bulky, bulky, excessive in strength, and poor in economy. [0003] At present, the basis for the manufacturing and inspection of process equipment parts is mostly drawings and three-dimensional digital models, especially for digital controls. When NC processing personnel compile NC machining programs based on drawings and digital models, it is not suitable to judge the machining accuracy of CNC machining profiles and holes. When it is required (especially for CNC parts with a ...

[0002] In the traditional aircraft assembly process equipment, there are a large number of aircraft parts to be assembled, high positioning accuracy requirements for process equipment, strict coordination dimensions, and a large number of riveting work. Therefore, the size of the frame is often determined based on experience, resulting in The frame is bulky, bulky, excessive in strength, and poor in economy

[0003] At present, the basis for the manufacturing and inspection of process equipment parts is mostly drawings and three-dimensional digital models, especially for digital controls. When NC processing personnel compile NC machining programs based on drawings and digital models, it is not suitable to judge the machining accuracy of CNC machining profiles and holes. When it is required (especially for CNC parts with a large number of profiles and holes), if some parts need CNC finishing, and some parts are only used for CNC rough machining, it is judged by CNC processing technicians based on experience based on drawings. The surfaces and holes in the digital model are all finished by CNC, which not only prolongs the processing cycle, but also wastes a lot of unnecessary processing costs

At the same time, it is difficult for three-coordinate inspection personnel to judge the accuracy and requirements of the profiles and holes to be inspected. They often perform all or multiple inspections on uncertain profiles and holes, resulting in unnecessary inspection costs.
