钢丝绳残余应力检测及分析
|
摘要
通过使用微区X射线残余应力仪Proto-LXRD对钢丝绳中直径0.5 mm的外层钢丝表面和不同深度的轴向残余应力检测,分析不同等温介质和常温时效时间对钢丝残余应力的影响及钢丝绳内残余应力的分布情况,阐述钢丝绳拉拔和捻制过程中影响残余应力的因素以及残余应力对钢丝绳性能的影响。
By using Proto-LXRD micro-zone X-ray residual stress meter to detect the axial residual stress on the surface and at different depths of the outer steel wire with a diameter of 0.5 mm in wire rope, the effects of different isothermal media and aging time at room temperature on the residual stress in wire rope and the distribution of the residual stress in wire rope are analyzed. The factors affecting residual stress during drawing and twisting of steel wire rope and the effect of residual stress on the properties of steel wire rope are expounded.
