Abstract :
[en] This paper proposes a piezoelectric vibration absorber, termed the nonlinear piezoelectric tuned
vibration absorber (NPTVA), for the mitigation of nonlinear resonances of mechanical systems.
The new feature of the NPTVA is that its nonlinear restoring force is designed according to a
principle of similarity, i.e., the NPTVA should be an electrical analog of the nonlinear host
system. Analytical formulas for the NPTVA parameters are derived using the homotopy
perturbation method. Doing so, a nonlinear generalization of Den Hartog’s equal-peak tuning
rule is developed for piezoelectric vibration absorbers.
