Abstract:With the continuous improvement of product quality and production efficiency of high-speed train industry product in China,the introduction and implementation of digital rail transit production lines have been promoted.Online calibration of automatic testing equipment has become a key factor in ensuring product quality.In this paper,the automatic wheelset detection equipment is taken as the research object,through a comprehensive discussion and analysis of its principle,structural composition,measurement model and metrology characteristics,an online calibration method for automatic wheelset detection equipment based on standard samples is proposed.The source of uncertainty in the measurement process is analyzed,and the measurement uncertainty is evaluated.The calibration test shows that the online calibration method can effectively compensate for the influence of various factors on the measurement results,and can evaluate the comprehensive measurement capability of the wheelset detection equipment with good standardization and operability.
Keywords:wheelset  automatic detection equipment  calibration  measurement uncertainty
