| Abstract [eng] |
The thesis objective is to investigate and propose a method that can be used to detect the crack in machine tool by analysing its natural frequency. Firstly the literature review of existing methods were done. Based on the existing methods, a new method was proposed and investigated, to detect the crack in machine tool, by conducting an experiment to analyse the difference in natural frequency on a cracked cantilever, with the help of piezo film sensor and data acquisition card. The data obtained from data acquisition card can be used for plotting natural frequency graphs in cantilever, with the help of LabVIEW software. By using ANSYS the same experiment is modelled. Finally the result obtained in experiment and modelling is compared. |
