Abstract: | Independent Component Analysis (ICA) was carried out to decompose engine vibration signals. Based on Fixed-point ICA algorithm, the conventional model for the vibrate signal of marine diesel engine was set up, analyses the property of vibration Signal. In view of the practical application, 2 route linear mixed sig- nals are carried on the separation, each independent component time domain and frequency range distribution is obtained. The result shows that ICA is an effective way to pretreatment of signal. |
