A New Experimental Method for Correcting Dispersion in Pressure Bar Measurements of Impulsive Force and Pressure

Arkadiusz Drobnica, Zdzislaw Kaczmarek
Abstract:
A method for correcting dispersive distortion inside a pressure bar, on the basis of experimentally determining the bar's dispersive characteristic is presented in the paper. For this purpose the continuous wavelet transform together with the Gabor analyzing function was applied. In this method, a one-point measurement of the strain inside the bar was used. The results of correction of impact force waveforms, generated by longitudinal impacts of steel spheres into a steel bar, are presented.
