Paper Abstract

Leadscrew is used to translate turning motion into linear motion. The alternative stress is happening during the motion, and fatigue may happen when the leadscrew undergoes reciprocating motion.The purpose of this study is to measure the deformation of leadscrew in-service by digital image correlation method (DIC) for fatigue failure evaluation. The leadscrew was undergoing reciprocating motion, and the deformed leadscrew images were captured by a CCD camera. Full-field strain of the deformed leadscrew was obtained by using digital image correlation, and to further obtain the full-field stress. The deformation at several points were examined. The results show that at the points of concentrated stress, the maximun Von Mises stress is about four times bigger than that at the other points, and fatigue may be occured.
