| Abstract: | A method to abstract vibration signals in this paper is presented for the first time. Different forms of frequency, amplitude and phase can be identified among vibration waves of various forms by this method.Modal shapes of vibration can be obtained when this method is applied in a mechanical structur together with multi-metering. This paper also provides an analogous result of a computer as a practical example. |
