| 摘 要： | 本文运用机械可靠性理论,将滚动轴承处理为由内圈,外圈和滚动体串联而成的机械系统,并认为它们的接触疲劳寿命服从三参数威布尔分布.在此基础上导出了以接触疲劳强度为基础的滚动轴承疲劳寿命预测公式.同时证明了Lundberg-Palmgren方法的寿命公式为新模型的一个特殊形式.

| Abstract: | Based on the mechanical reliability theory, a rolling bearing is treated as a system consisting of an inner ring, an outer ring and Z rolling elements in series. The fatigue life formula based on contact fatigue strength is derived, assuming that the fatigue life of three components in the system follows the three-parameter Weibull distribution. It is shown that the fatigue life formula by the Lundberg-Palmgren's method is a special form of the new model. |
