Experimental Characterization And Performance Of Dynamic Vibration Absorber With Tunable Piecewise-Linear Stiffness

Dynamic vibration absorber (DVA) is one of the ways to control the level of vibration. Among many mechanisms and control strategies of the DVA, passively tuned DVA emerges as one of the most efective absorbers due to its simple mechanism. However, the performance of the passive tuned DVA sufers from...

This paper introduces a nonlinear dynamic vibration absorber (NDVA) with an adjustable piecewise-linear stifness mechanism which has a characteristic almost similar to hardening stifness to broaden the vibration suppression bandwidth.
