Abstract
This study deals with piezoelectric shunt damping in the mistuned
bladed disks. Bladed disks are rich dynamical systems that are known
to suffer from severe vibration problems. Blade mistuning is an issue
of major concern since it is responsible for high cycle fatigue and
failure risks. In the mitigation practice, additional damping is usually
introduced into the structure to reduce vibration amplitudes. Here,
weareinterestedinpiezoelectricshuntdampingappliedintomistuned
bladed disks.
In our proposed damping strategy, shunted piezoelectrics are attached
onto the disk surface between adjacent blades in order to dissipate
the disk mechanical energy. Consequently the blade vibration can
be reduced due to the blade-disk coupling. This strategy is of engi-
neering interest since piezoelectric transducers are placed outside of
the main stream in turbomachinery. This idea is developed based on
a lumped-parameter bladed disk model. Resonant shunt circuits are
adopted. Both piezoelectric shunt damping and optimized piezoelec-
tric mistuning are introduced to minimize the blade mistuning effect.
Piezoelectric mistuning can be seen as a kind of damping mistuning;

circuit.
In reality the blade mistuning pattern is not constant in the long run.
Due to various complexities, a perturbation of the blade mistuning
pattern might result. In benefitting from the manageability and con-
trollability of piezoelectric shunt circuits, an adaptive control strategy
is developed to adjust the optimal piezoelectric mistuning pattern ac-
cording to the perturbation. Numerical simulations reveal that a fine
