| Abstract: | In this thesis,the vibration experimental analysis of electric cloth-cutting machine has been done by nmcans of cmplying the hammer-pulse exciting test manner and the mcirocomputer ynamic signal sampling and analysis techniques.The vibration frequency structure and model are also defined.On the basis of transfer function calculation of the vibration signals and the Nyquist curve fitting,the autbors have obtained the dynamic cbaracteristic parameters such as each order natural frequency,damping ratio etc,in the test and analysis of electric cloth-cutting machine.A feaaasible way to improve the dynamic characteristics of this machine is provided in practice. |
