In order to investigate the influencing factors on the fatigue life of electroforming corrugated tubes under bending conditions,this study conducted corresponding rotational bending fatigue experiments using a bending test fixture,and analyzed the experimental results.The results indicate that in the bending fatigue experiments,the fracture of electroforming corrugated tubes occurred is at the trough,and all fractures are ductile.With the decrease in the wall thickness of the electroforming corru-gated tubes,the increase in the wave height,the fatigue life increases.Compared with the bending limit angle,the fatigue life of electrodeposited corrugated pipes increases by 6.8 times under normal working conditions.The experiment shows that the fa-tigue performance of multilayer electroforming corrugated tubes with a wall thickness of 0.03 mm,a wave height of 2.3 mm,and a working bending angle of 110° is the best.
