Investigation of Impact Hammer Calibrations

M. Kobusch, L. Klaus, L. Muñiz Mendoza

Abstract

This paper presents recent theoretical and experimental investigations of calibration measurements of impact hammers using different dynamic calibration set-ups with primary traceability methods. In the scope of a scientific collaboration between the German national metrology institute PTB and the Mexican CENAM, measurements of selected hammers were conducted at both institutes. The analysis of the measurement signals in the time and frequency domain is presented and discussed. modal hammer, dynamic calibration, shock force, sensitivity
