Application of active vibration control on single stage spur gear

Abstract

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.

Active vibration control of gearbox housing using inertial mass actuators

“…Britta Späh [29] worked on the identification of the dynamic system properties of a transmission system, exploring suitable areas for positioning the actuators and the possibility of using piezoelectric surface transducers to control the gearbox housing. Raman Menon et al [30] developed a feedback control loop to reduce the vibrational noise produced by transmission errors of spur gears. They incorporated the modal analysis of the spur gear into the Simulink through state space form.…”
