“…Thus, it appears that above this excitation level an extra nonlinear mechanism altered the softening response characteristic due to PZT nonlinearity. An earlier research investigation on the design of a ultrasonic system has indicated that, at high power, the local stiffening of the joints may kick in, affecting the system behaviour [7]. Another study showed that the position of the threaded stud within a joint affected the nonlinear characteristic of a power ultrasonic cutting system [1].…”

In ultrasonic drilling, cutting and welding applications, ultrasonic devices are needed to generate large vibration velocities. It is renowned that whilst these devices are driven at high power their dynamic behaviour tends to exhibit nonlinear features. Until a fundamental understanding of this behaviour will not be achieved, and effective ways to control it developed, high power ultrasonics will unlikely find utilize in large scale industrial processes. This study is focused on the characterisation of the nonlinear behaviour of two power ultrasonic devices designed for rock drilling.
