Abstract
Numerical simulation and automated optimization of Langevin-type
ultrasonic transducers are investigated. These kind of transducers are
standard components in various applications of high-power ultrasonics
such as ultrasonic cleaning and chemical processing. Vibration of the
transducer is simulated numerically by standard finite element method
and the dimensions and shape parameters of a transducer are optimized
with respect to different criteria. The novelty value of this work is
the combination of the simulation model and the optimization problem by
efficient automatic differentiation techniques. The capabilities of this
approach are demonstrated with practical test cases in which various
aspects of the operation of a transducer are improved.
