钢轨中残余应力的产生、影响及调控研究现状
Review on production,influence and control of residual stress in rail
摘要
Abstract
In recent years,with the rapid development of high-speed and heavy-haul railways in China,higher requirements are put forward for the reliability of rail service performance.If there is excessive residual stress and adverse distribution state in the rail,it is easy to promote the formation of fatigue cracks and accelerate the propagation,which seriously affects its service performance.In this paper,the current measurement methods of residual stress in rail are summarized.In addition,the source of residual stress and the influence of residual stress on comprehensive performance of rail are discussed.At the same time,according to the technological process of rail production,such as pre-bending,cooling,straightening,tempering,the research achievements in the field of rail residual stress evolution and control are reviewed.Finally,the development of rail residual stress evolution and control technology are prospected.关键词
