Vibrations in a mechanical system can cause power losses or vibrational fatigue which leads to failure in the material. In the current scenario automotive vehicles majorly use passive vibrational control techniques for vibration attenuation. Passive vibrational control tend to be heavy in nature and can only control frequencies in the range of 100 – 200 Hz. Conversely, active vibrational control is the potential alternative to passive vibrational control, they consist of strain sensor, piezoelectric actuator, a control system and a power amplifier to draw the control actuator. The application of active vibrational control is flourishing due to the demand in critical vibrational control in extreme conditions (underwater, polar, space). This paper provides an overview of the applications of active vibration control on single stage spur gear. The vibrations emitted in a single stage spur gear is optimised by active vibration control.
