Abstract:
T his paper describes drop hammer hydraulic dynamic-calibrat ion device. s operating principle and it s main funct ion. The problems of the current calibration methods are also studied in details. In order to improve the calibrat ion system’s accuracy, an absolute calibration method is introduced. A low-price and high-accuracy force transducer is used to replace pressure transducer to realize dynamic pressure absolute calibrat ion. The significance of the method is analy zed. The way of how to put the method into effect , and the theoret ical proof of the calibration accuracy are all stated. The experiments have proved the feasibility of the method.
