摘　　要：针对采用传统人工方法检定铁路机车车辆专用压力表中存在的效率低、影响测量结果准确性等问题,设计一种专用压力表双工位自动检定装置。提出专用压力表双工位自动检定装置设计要求,设计双工位自动检定装置整体结构,分析双工位自动检定装置工作原理,重点阐述关键技术设计,并评定专用压力表双工位自动检定装置测量结果不确定度。评定结果表明,测量结果扩展测量不确定度小于最大允许误差绝对值的1/3,具备对专用压力表量值溯源能力。应用效果表明,使用双工位自动检定装置检定专用压力表,不仅能够提升检定效率,提高检定结果准确度,而且自动化程度高,操作简便。In response to the problems such as low efficiency and affecting the accuracy of measurement results mea-sured by traditional manual methods for verifying bourdon pressure gauge for railway locomotive and vehicle,an auto-matic verification device with dual work station for bourdon pressure gauge is designed.Design requirements for the automatic verification device with dual work station for bourdon pressure gauge are proposed.The overall structure of the automatic verification device with dual work station is designed,and the working principle of the automatic verifi-cation device with dual work station is analysed.The key technical design is emphasized,and the uncertainty of the measurement results of the automatic verification device with dual work station for bourdon pressure gauges is evalu-ated.The evaluation result shows that the extended measurement uncertainty of the measurement results is less than 1/3 of the absolute value of the maximum allowable error,and it has the ability to trace the values of the quantity of the bourdon pressure gauge.The application effect shows that using the automatic verification device with dual work station to verify the bourdon pressure gauges,can not only improve verification efficiency and accuracy of verification results,but also have a high degree of automation and easy operation.
