Verification of Mathematical Model of Mechanical System of Needle Bar using Laser Doppler Vibrometer

Popis výsledku v původním jazyce

This paper deals with verification of the accuracy of the mathematical model of the mechanical system of the needle bar. A special needle bar is part of the sewing machine, which creates a decorative stitch. In order to modify the selected mechanical system of the sewing machine for a purpose of reduce the vibrations and noise, a mathematical model was created. The parameters of the mathematical model were previously approximately determined. To refine these parameters, experimental measurements were performed using a Laser Doppler Vibrometer, thanks to which the kinematic quantities of selected parts of the mechanical system were obtained. The obtained curves were evaluated and compared with the results of the analysis of the mathematical model behaviour
