The Practicable Testing Method of the Zero-stress Temperature of the Seamless Rail

超长无缝钢轨零应力轨温实用测试方法

Based on the urgent needs and practical significance for the seamless rail safety monitoring , this paper carried out the research of the distributed wireless monitoring system for rail stress .

本文针对无缝钢轨安全监测的迫切需求和现实意义，开展了分布式钢轨应力无线监测系统的研究。

Seamless rail plays the role of guiding and hosting the train , it has become imperative to monitor the health status of the seamless rail .

无缝钢轨起着列车导向和承载的作用，监测无缝钢轨的健康状况已成为当务之急。

Because the reserved space of the seamless rail is very short , the changing temperature will bring more greater impact to the seamless rail than the common rail .

由于无缝钢轨的预留间隙很小，因此温度变化对无缝钢轨的影响比传统钢轨要大的多。

The region 's leaders have dreamed since the1990s of seamless rail travel between Singapore and Kunming , capital of the south-western Chinese province of Yunnan .

东南亚的领导人们从90年代就开始梦想着从新加坡到昆明（中国西南的云南省省会）的无缝铁路。

However , when the temperature changes , the seamless rail in a locked state can not be freely expanded and contracted , which will cause a great internal longitudinal stress and will lead to the track damage if the safety range is exceeded .

但当温度发生变化时，由于其处于锁紧状态不可以自由伸缩，导致其内部产生很大的温度应力，如果超出安全范围就会导致钢轨损伤。

Rail fixing system is a basis to ensure stable and safe operation of crane . With an analysis on the rail stress , the Paper compares and illustrates the advantages and disadvantages of seam rail fish plate rigid fixing system and seamless rail flexible fixing system .

轨道固定系统是起重机平稳安全运行的基础，文章从轨道的受力分析出发，比较说明有缝轨道鱼尾板硬式固定系统和无缝轨道柔性固定系统的优缺点。
