A COMBINATION METHOD OF THEORY AND EXPERIMENT IN DETERMINATION OF MACHINE-TOOL DYNAMIC STRUCTURE PARAMETERS

Abstract

In this paper, a combination method of the theory and experiment in determination of dynamic parameters of machine-tool system was proposed. By experimental research, the data of action force and the vibrations was collected in time domain. By the theoretical research, using Fourier Transform, the data in time domain was transformed and analysed in frequency domain. And then, the parameters of the machine-tool dynamic structure were determined. The proposed method was verified by the comparison of the calculated results and the analysed results from analysis software.
