Abstract

To obtain the characteristic life of a chain tool magazine and automatic tool changer under normal working condition, a small-sample accelerated life test method was developed. The inverse power law model and small-sample virtual augmented theory was applied while taking vibration as the accelerated stress. The accelerated life test of the automatic tool changer was carried out under different stress levels. The results showed that the “Mean Cycles between Failures” of exchanging tool under normal stress was about 28283 times for the chain tool magazine and automatic tool changer. The proposed small-sample accelerated life test method, which based on the inverse power law model, could also be used in other relevant large-scale and complex products.
