| Abstract: | This paper introduces a special modal analysis test, in which the force hammer is used to excite horizontal machine tools and varied time base sampling method is used to sample force and response signal. Dynamic characteristics of the machine tools are studied, and its lower order of natural frequencies are obtained. Through the analysis of the modal characteristics of this machine tools, its relative weaker parts are pointed. The improving suggestion for this machine tools is put forward accordingly. |
