The fabric clip is an important component in textile machine. The creep deformation on the clip body hole at high temperature acted on different pulling forces during a period of 6 240 h was researched by using ABAQUS software. The Norton-Bailey's with time hardening constitutive equation was used to simulate the creep deformation on the clip body hole made of A380 aluminum alloy at high temperature, and the simulation results showed that for different pulling forces, the creep deformation on the clip body hole increased with an increase in the pulling force. Then, the experimental dimensional changes test was performed on three different specimens of the clip body hole at different service time(l 200 h, 4 800 h, 6 240 h) by using a Global Performance test machine. A comparison between the finite element method (FEM) and the experimental results show a good correlation. The simulation results also indicate that the creep deformation on the clip body hole has an important effect on the relaxation of the blade clamping fastness which leads to fabric clip failure.
