| 摘 要： | 超长无缝钢轨减少了列车行驶过程中的振动。为保证行车安全,必须将轨温升高引起的钢轨压力限制在一定范围内,以免压屈现象发生。为确定温升引起的压力,须计算出钢轨中零应力所对应的温度(简称零应力轨温)。如何测出零应力轨温就是本文的研究内容。 |
| 关 键 词： | 无缝钢轨 零应力轨温 实用测试方法 |

| Abstract: | The application of seamless rails reduces train vibration. To ensure safety, the pressure existing in the rail, caused by temperature increasing, should be limited to avoid buckling. To determine the pressure value, the temperature corresponding to the zero-stress of the rail should be calculated. This article focuses on the practicable testing method of the zero-stress of the rail. |
| Keywords: | seamless rail zero-stress rail temperature practicable testing method |
