Abstract EN
The improvement of ultrasonic phased array detection technology is a major concern of engineering community.
Orthotropic piezoelectric fiber composite (OPFC) can be constructed to multielement linear array which may be applied conveniently to actuators and sensors.
The phased array transducers can generate special directional strong actuator power and high sensitivity for its orthotropic performance.
Focusing beam of the linear phased array transducer is obtained simply only by adjusting a parabolic time delay.
In this work, the distributed point source method (DPSM) is used to model the ultrasonic field.
DPSM is a newly developed mesh-free numerical technique that has been developed for solving a variety of engineering problems.
This work gives the basic theory of this method and solves the problems from the application of new OPFC phased array transducer.
Compared with traditional transducer, the interaction effect of two OPFC linear phased array transducers is also modeled in the same medium, which shows that the pressure beam produced by the new transducer is narrower or more collimated than that produced by the conventional transducer at different angles.
DPSM can be used to analyze and optimally design the OPFC linear phased array transducer.
