摘要
采用SN 2 5拖拉机半轴的疲劳寿命表达式和Miner定则 ,预测了半轴在其原始载荷谱下的疲劳寿命 。
The expressions of fatigue life are presented for shaft of SN 25 type tractor by statistically analyzing the test data. According to the procedures outlined, one can use the fatigue life expression mentioned and the linear damage accumulation rule proposed by Miner to predict the fatigue life of shaft of tractor under original load spectrum. A good agreement is achieved between the predicted results and the service life.
