论文部分内容阅读
北美铁道协会研究试验部副主任斯蒂尔(R.K.Steele)和主任斯通(D.H.Stone)都是金属学者,多年从事铁路钢轨的研究工作。在1986年北美铁道工程学会的年会上联名发表了题为“铁路钢轨的新发展”一文,后来刊登在该学会的1986年第87卷第707期论文集中。这篇论文不但涉及到改善钢轨材质的问题,而且还从轮轨关系的角度讨论了改进钢轨顶面外形的设计等问题,内容十分丰富。由于原文篇幅较长,特将其重点摘出介绍给读者。
R.K. Steele, deputy director of research and testing at the North American Railway Society, and D.H.Stone, both metallovers, have been engaged in the research of railroad tracks for many years. In 1986, North American Society of Railway Engineering Annual Meeting jointly issued a paper entitled “New Development of Railway Rails,” which was later published in the Institute’s 1986 Volume 87, Issue 707. This paper not only relates to the problem of improving the rail material, but also discusses the design of improving the top shape of the rail from the wheel-rail relationship, which is very rich in content. Due to the length of the original text, special emphasis on its introduction to readers.
