The reason of the self-excited vibration of the vehicle-guideway coupling vibration system was explored by establishing a single iron suspension model (Li, Li, and Zhou 2014).
Resonance and flutter produced by the forced vibration and self-excited vibration are the main reason leading to the blade failure.

The self-excited vibration, called chatter, is one of the main limitation in metal removal processes.
However, previous studies on brake noise that investigated the friction characteristics mainly considered the self-excited vibration at a specific friction coefficient or unstable vibration caused by the negative slope in the relative velocity versus the friction coefficient curve [13-15].
The self-excited vibration of hot strip mill was studied, and the variation of the rolling torque caused by rolling speed was obtained [4].
Under continuous machining conditions, two types of vibration occur as a result of movement between a work-piece and tool: external vibration (result of interference force transmitted through the foundation into the machine); self-excited vibration, (the machine system oscillates, basically, at one or more natural frequencies, when no external forces are acting).
An all-digital MEMS tuning fork self-excited vibration control by phase-relation using time-A/D converter- (TAD-) based all-digital PLL (ADPLL), which uses no conventional analog method such as automatic gain control (AGC) or automatic level control (ALC), has been presented [10].
When the sprung mass varies from big to small, this slowly varying damping coefficient is negative, resulting in self-excited vibration. Meanwhile, the natural frequency is slowly varying, leading to slowly varying amplitude and phase angle.
