The fretting fatigue life under complex loads monotonously decreases with the increase of the high cycleload while the lowcycle loads keep constant.
复合载荷下,低周幅值不变,增加高周载荷的幅值,微动疲劳寿命随幅值比的增加而降低。

The load displacement curve under static load, load displacement hysteric curve under repeated lowcycleload and strain data at key points are presented.
给出了静力荷载下的荷载变形曲线、低周反复荷载下的荷载变形滞回曲线以及关键部位的应变数据。

Under the same strength technique conditions, the size of lowcycle fatigue load will influence the strength effect, and the smaller load means more obvious effect.
