A source programme has been written to computer the drilling load oscillogram of a striking-penetrating system. The theoretical estimation of the fatigue life of the drill rod is carried out bY analyzing the rule and constitution of the load spectrum and its influence on the surplus life of drill rod. 收稿日期: 1986-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 宋守志 徐小荷 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I5/134 1 Newland, D.E., An Introduction to Random Vibrations and Spectral Analysis, Longman Group Ltd., Edinburgh, 1975, p. 42． 2 徐小荷,岩石力学与工程学报,3(1984) ,№1,75． 3 长沙矿冶研究院;贵阳钎钢研究所,矿冶工程,5(1985) ,№1,3． 4 徐濒,疲劳强度设计,机械工业出版社,1981,P.210． 5 宋守志;徐小荷;李润隆,钢铁,21(1986) ,№3,30．?
