The compliance is very sensitive to internal mechanical factors concerning the load system, as the hammer, the tup, the anvils and the base to foundation attachement. In order to verify the sensitivity of compliance measurements, a series of experimental tests has been performed, with artificial and real defect located at the most critical parts. In order to overcame the need of an instrumented impact tester an instrumented specimen has been prepared, together with its electronic system for impact tester compliance measurement. The compliance measurement, after verification of the impact tester with direct and indirect methods, as per ASTM E 23 or ISO R 442, can be helpful for verification of the good working condition of the pendulum and for the detection of onset of anomalies.

Abstract

The compliance is very sensitive to internal mechanical factors concerning the load system, as the hammer, the tup, the anvils and the base to foundation attachement. In order to verify the sensitivity of compliance measurements, a series of experimental tests has been performed, with artificial and real defect located at the most critical parts. In order to overcame the need of an instrumented impact tester an instrumented specimen has been prepared, together with its electronic system for impact tester compliance measurement. The compliance measurement, after verification of the impact tester with direct and indirect methods, as per ASTM E 23 or ISO R 442, can be helpful for verification of the good working condition of the pendulum and for the detection of onset of anomalies.
