Study on the Force of Flexible Vacuum Cup Fixture for Aircraft Skin Trimming

Abstract:

When the aircraft skin is in the process of trimming and on the flexible vacuum cup fixture, by analyzing the stress to the aircraft skin and studying the relationship between vacuum pressure and deformation of aircraft skin, vacuum pressure, vacuum force and cutting parameters, the relationship which between vacuum pressure of flexible fixture and cutting parameters, clamping points of flexible fixture, friction coefficient of cup and aircraft skin, the maximum deformation allowed on aircraft skin is obtained. It provides a methodology to improve the precision of trimming of aircraft skin components.
