摘要
受力不均、夹持损伤和应力集中是影响钢绞线脉动拉伸疲劳试验的三个关键问题。针对这三个影响因素 ,提出了相应的三项改进措施及试验方法 ,并设计试制了一种与此配套的双层叠加式夹具 ,使试验在较高应力水平下取得了满意的结果。
The uneven distribution of loading, the clamping damage and the stress concentration were thought to be the three key factors influencing the fatigue test of steel strand with pulsating tensile load. To these three influence factors, the improving measure and the test method have been proposed correspondingly, and a set of doubly piled clamping apparatus also has been designed, under which the fatigue test was carried out successfully at higher level of stress.
