绳索取心钻杆螺纹疲劳试验

Rod serew fatique testing for wire rope sampling

钻杆螺纹疲劳试验可以为钻杆螺纹参数设计提供试验依据,因此具有重要意义。本文介绍了国内首次对绳索取心钻杆螺纹进行疲劳试验所用装置及试验有关参数的确定和计算方法,可供今后进一步完善试验参考。

The rod screw fatique testing may present data for rod screw design parameters. Therefore, it has important significance. This paper introduces the equipment of rod screw fatique testing for wire rope sampling and the determination and calculation of the testing parameters. These works are the first time done in China. This paper may serve to improve such kind of testings hereafter.
