A new multiaxial fatigue life prediction method based on grey theory under small sample condition

Abstract: It is always a challenge to accurately predict the fatigue life of specimens in engineering, and it is urgent to establish a convenient and accurate approach to estimate the fatigue life of specimens with different materials under small sample conditions. To solve the above problems, a new multiaxial fatigue life prediction method is proposed based on grey theory. First, established a modified MGM (1, N) model by fine-adjusting the time series based on the GM (1, N) model. Then the MGM (1, N) model is used to … Show more

“…The key dimension measurement of train wheelset is taken as the starting point and the safe operation of the train is ensured as the foothold. Besides, the measured key dimensions can be used to study the fatigue life and reliability of train wheelsets [44][45][46][47]. The mechanical structure of the wheelset measurement system is built by analyzing and studying the fast measurement algorithm of the key dimension of train wheelset based on image processing.…”
