Abstract

The directivity function of orthotropic piezoelectric composite materials (OPCM) ultrasonic linear array is deduced by constructing a mathematic model of acoustic field on a new OPCM ultrasonic phased array actuator/sensor, which is based on the 1-1 mode OPCM. By calculating scatter feature of acoustic field in space and analyzing the effects of change in structure type and dimension on main lobe and side lobe of array, optimal array parameters of new OPCM ultrasonic phased array actuator/sensor, such as operating frequency, array interval, array width and array number are obtained. The developed OPCM actuator/sensor elements are applied in detecting the simulated damage in aluminum plate. The testing results show that the damage detection precision is further improved by using OPCM ultrasonic phased array actuator/sensor.
