| Abstract: | Experimental modal analysis(EMA) is one of most methods to analyze the dynamic characters of machinery.The application of EMA in machine tools' structure dynamic features is illustrated in order to improve the dynamics performance.A set of modal analysis system for machine tools is developed on the platform LabVIEW combined with Matlab based on modal analysis theory and modal testing technology.A case of spindle assembly of a vertical CNC machine tools is implemented and the results are given to verify the functions of the developed system. |
