基于变载荷的滚动轴承疲劳寿命强化试验

摘要

The fatigue life intensification test for rolling bearings based on variable load is studied by using eight-level test load spectrum under multi -operating conditions.The intensification rule is confirmed for eight-level test load spectrum under multi-operating conditions,and the intensification test scheme is formulated.The fatigue life intensifi-cation tests are carried out for rolling bearings under constant load and variable load,and the test data is processed. The results show that the intensification test scheme and data processing method are reasonable and correct.%采用多工况8级试验载荷谱对基于变载荷的滚动轴承疲劳寿命强化试验进行研究，确定强化准则，制定强化试验方案，进行常载和变载滚动轴承疲劳寿命强化试验，并对试验数据进行处理。结果表明，强化试验方案及其数据处理方法是合理和正确的。
