| Abstract: | This paper presents an approach of vibration measurement and analysis by incorporating a microcomputer system in industrial rigid support dynamic balance machine. Measurement accuracy is improved by taking samples from vibration signal in whole number cycle. Precise information of amplitude and phase of vibration signal related to unbalance is obtained by making digital processing for discrete sampled data with sine-cosine correlation in time-domain. In order to ensure higher accuracy, a new method is used in this paper. The prototype machine developed gives satisfactory balance results. |
