  • METHOD FOR TRACEABILITY CALIBRATION OF CALIBRATION DEVICE OF ROCK CHISELING SPECIFIC POWER TESTER
    Publication number: 20230304884
    Abstract: A method for traceability calibration of calibration device of rock chiseling specific power tester includes static calibration and dynamic calibration. Static calibration includes: placing impact indicator sensor of calibration device on static calibration stage; installing standard weight holder on adapter head of impact indicator sensor; adding a standard weight to standard weight holder several times; and calculating static coefficient k. Dynamic calibration includes: placing impact indicator sensor on dynamic calibration stage; resetting dynamic calibration coefficients a and b of calibration device; recording standard impact energy W0 of dynamic standard hammer and measured indication value W of impact indicator sensor to obtain standard deviation S=W?W0; and calculating dynamic coefficients a and b. Rock chiseling specific power magnitude is effectively traced to equal mass standard of standard weights. A new traceability method and system for specific power magnitude is constructed.
