Dynamic effects of piezoelectric patch actuators on vibrational response of non-deterministic structures: modelling and simulations
Many engineering systems such as aircraft and automotive are considered built-up structures, fabricated from components that are classi fi ed as deterministic subsystems (DS) and non-deterministic subsystems (Non-DS). The response of Non-DS is sensitive to minor details of material properties, geo...

| description | Many engineering systems such as aircraft and automotive are considered
built-up structures, fabricated from components that are classi fi ed as deterministic
subsystems (DS) and non-deterministic subsystems (Non-DS). The response of
Non-DS is sensitive to minor details of material properties, geometry, connections
and damping distribution; therefore create problems in vibration control. Hence, the
response of Non-DS is estimated using statistical modelling technique such as sta-
tistical energy analysis (SEA), in which any external input to the subsystem must be
represented in terms of power input. In this research, ensemble average of power
delivered by a piezoelectric (PZT) patch actuator to a simply-supported plate when
subjected to structural uncertainties is studied using Lagrangian method and
obtained by Monte-Carlo simulation. The effects of size and location of the PZT
patch actuators on the power delivered to the plate are investigated. It is found that
changing the patch location on the structure will not affect the average power sup-
plied by the patch while changing the patch size will change the power magnitude
proportionally but with some variations at higher frequency. |
