Transform a Mechanical Testing Machine into High-Temperature Disk Spring Stress Relaxation Test Equipment

Abstract:

Prediction of disk spring failure life due to stress relaxation is necessary for users; the problem was not solved before. According to special test requirement, we modified a 100N mechanical testing machine into high temperature testing equipment which can be used for different types of disk spring. With a test for 36 days on a group of 45×22.5×3.5×2.5 mm disk springs, a result of prediction of 3.38% load loss ratio after 12 years relaxation is obtained, these disk springs are qualified. Our modified equipment has the advantages of real time, heavy loading, high sensitivity and good generality.
