| Abstract: | Taking 14×6JJ alloy wheels for automotive research, in the load spectrum based on the analysis, using the estimation of high accuracy and safety of the cumulative damage theory-Miner rule amendments for the wheel load variation of fatigue strength evaluation and life estimation. With the use of reliability theory, the predicted lifetime reliability wheel was calculated. The results showed that the amended rules Miner vehicle wheel to predict the fatigue life with high reliability. |
