| Abstract: | The basic principles of the experimental modal analysis,the sensitivity analysis and the local structural modification analysis, which are the advanced dynamic modification technique, are introduced and are applied to compute and analyse a frame of the Y112M-4 type motor, and the modification project is determined. Experimental results show that this modification measure can efficiently prevent transmission of the electric-magnetic vibration and noise of the motor and has an obvious effect in reducing vibration and noise. |
