摘要

Interference-fit is the main joint mode of the aircraft composite components, however, improper interference-fit percentage will lead to the onset and the expanding of the damage around the hole. Currently, the interference-fit percentage is decided only through experience, and theoretical foundation is lacked. This paper first analyzes the stress condition of the interference-fit joining process, and constructed the stress distribution model based on interference-fit percentage. Based on this, damage onset model is constructed combined with the Yamada criterion, and the damage expanding model is constructed with the help of the Characteristic curve method; Secondly ABAQUS is used to simulate the interference-fit joining process; Finally contrast is made between the numerical and experimental of joints with different diameters, and the result of the contrast shows that the damage region onset and expanding model and the degeneration model are good.
