Abstract:

The paper presents the causes of appearance and also the effect of noise on human body. One of the causes is the noise and vibrations produced when shafts pass through critical speed. The paper presents a method to active control the shafts passing through critical speed by changing the rigidity of supports with the help of memory metals. Through this method the vibration of the shaft due to whirling is controlled by means of heating (on) and cooling (off) of memory metals for bearing supports.
