Abstract:

       We designed a calibrating rack for calibrating contact wire geometry measuring instrument. It included simulation contact wire component and simulation rail component and could determine such critical parameters as contact wire height and stagger value. Evaluation on measurement uncertainty of related parameters shows that the device can calibrate and adjust a measuring instrument with 1 grade accuracy. Practical application demonstrates that the device is stable and reliable.

Key words: calibrating rack, contact wire height, stagger value, measuring instrument for contact wire geometry
