VIBRATION SUPPRESSION BY MODULATION OF ELASTIC MODULUS USING SHAPE MEMORY ALLOY
A method is proposed for supps'essing the resonances that occur as an item of rotating machinery is spun-up from rest to its operating speed. This proposed method invokes “stiffiness scheduling” so that the resonant frequency of the system is shifted during spin-up so as to be distant from the excitation frequency. A strategy for modulating the stiffness through the use of shape memory alloy is also presented.
