Abstrakt: Our paper in the last “Interaction and feedback 2012” conference has been oriented on the influence of force transducer’s mounting on its signal. The presented paper links on the previous contribution and concentrates on the problem of recording time histories of discontinuous periodic forces. The frequency spectrum of sudden jumps in force courses contain many high components, some of them can be laying near to some of the system’s eigenfrequencies. The excitation of these higher oscillations can essentially distort records of force jumps. Unfortunately, the application of low pas filter cannot be used, as it deletes both distorted frequencies as well as these same frequencies in the jumps signal and distorted it again. One of the possibilities how to solve this problem is using special evaluation procedure that enables to estimate (at least approximately) the real measured force. This evaluation method can be used successfully at measurement of dry friction forces arising during vibration’s tangential contact.
