Desigh and Analysis of Railway Nominal Dimensions Inspection Sample Plate

钢轨型式尺寸是关系钢轨质量优劣的一项重要指标,钢轨生产和验收过程中必须对钢轨型式尺寸进行准确检测。对钢轨型式尺寸检查样板的设计进行了分析,按照样板设计原则计算了各类样板的公称尺寸,研究了样板使用过程中磨损对测量结果的影响,总结了钢轨尺寸检测与控制中样板使用的注意事项。研究内容对于规范日常钢轨型式尺寸检测、提高钢轨型式尺寸检测准确性、提升钢轨质量有借鉴意义。

The nominal dimensions of rails are important indicators of the rail quality,and its compliance with the standard must be accurately tested during the production and acceptance.The design of the sample plate was analyzed and the nominal dimensions of each sample plate were calculated according to the design principle,the influence of each sample plate wear on measurement results during the use was studied,the different effects of each sample plate wear on the measurement results and the precautions for the use,regular calibration and daily verification were obtained.The rail inspection was standardized to improve the detection accuracy and quality of the rail.
