Abstract

Abstract: This paper reported the study on the service life prediction of cable ties used for high-speed trains through hot-air accelerated aging according to Arrhenius equation. The relationship between aging time and stretching strength was investigated, and a predicting model was established. The service life of the cable ties was analyzed and predicted by an MATLAB software, and the obtained data were proved by the least square method. The results indicated that the service life of the cable ties was predicted as 28.44 years at a room temperature of 25 ℃.

Key words: polyamide cable tie, Arrhenius equation, hot-air accelerated aging, service life, prediction
