摘要: 在提出8(1/2)”XHP3S牙轮钻头失效判据的基础上,较全面地分析处理收集到的现场数据,得出了失效寿命分布规律、失效率曲线、可靠度函数及磨损与寿命、可靠度的经验公式,并对可靠度计算方法作了讨论,区分了钻头理想的可靠度与实际的可靠度.获得经验公式时剃除了异常数据.

关键词: 失效判据, 失效寿命, 可靠度, 磨损

Abstract: The detailed field data is presented on the basis of failure criterion of 8(1/2)"XHP3S rock bit, resulting in Life Distribution, Failure Rate Curve, Reliability Function and the empiric formula of wear versus life, reliability. A method of reliability calculation and the difference between idea reliability and practical reliability are presented. Those unconventional data are eliminated when studying the empiric formula. These jobs as well as the results are the first in and abroad.

Key words: failure criterion, life, reliability, wear
