1-2 HOURS

NPTEL

 width=This course covers the principles and applications of non-linear vibration absorbers. It provides a comprehensive understanding of different types of beams, such as elastic, viscoelastic, and elastomagnetic beams, and their conversion into energy harvesters. The course delves into the stability and bifurcations of non-linear systems, including pitchfork, saddle load, and hop type of bifurcations. It further explores the use of vibration absorbers to control or isolate vibrations in systems, with examples from engineering structures and machines. The course also discusses the use of piezoelectric stack actuators in vibration absorbers and the analysis of active non-linear vibration absorbers by displacement and acceleration feedback. The course concludes with a detailed analysis of a piezoelectric stack actuator-based active vibration absorbers.
