| 10. | Recently , train is running faster and faster , and considering the stability and security , seamless welded rails ( swr ) are used as the train orbits gradually . the temperature of the rails will vary with weather . so that the rails may release the energy due to the metal characteristic of expanding or contracting with temperature , there is some badly distortion in the swr , worsly occurring accidents on expanding orbits . the portrait thermal stress ( pts ) of the swr should be monitored in some parts regularly , as to avoid such accident
近年来,随着火车的提速造成的稳定和安全问题,轨道逐步转为采用无缝焊接钢轨,随着钢轨温度的变化,无缝钢轨可能会因为热胀或冷缩的金属特性并且在扣件阻力小而且路基较差的路段释放能量,可能会发生钢轨严重变形,更甚者会发生胀轨跑道等严重铁道事故,为了避免发生如此事故,有必要定期对钢轨的温度应力进行检测。 |
