Introduction to Self-Excited Systems

Self-excited systems are those in which the motion of the system itself produces sufficient excitation to sustain an oscillation. There are many such phenomena, and in this chapter we introduce a few of the more important practically. Those discussed are the following:

(a) Vibration induced by friction, which can occur when the rubbing surfaces of items such as tires on runways, brakes and clutches have a coefficient of friction which tends to decrease with increasing velocity.

(b) Aircraft flutter, a branch of aeroelasticity, where the aerodynamic driving forces are derived from the airstream by the elastic ...
