Acoustic Beam Simulation
Definition - What does Acoustic Beam Simulation mean?
An acoustic beam simulation makes use of ultrasonic beams that are used in a phased array (PA) ultrasonic, which is considered to be an advanced method of ultrasonic testing.
This method is better at finding flaws in manufactured materials such as welds. The acoustic beam simulation mimics how the ultrasonic beam in a PA probe can be focused and swept electronically without moving the probe and how the beam is controlled in a real world scenario. A phased array probe is made up of multiple small elements, each of which can be pulsed individually at a computer-calculated timing.
This technology finds applications in the field of medical science and non-destructive testing.
Corrosionpedia explains Acoustic Beam Simulation
Acoustic beam simulation is the imitation of a real-world process or system using acoustic ultrasonic beams with phased array technology. In the real world, the ultrasonic beams are controlled through a computer based software program using the phased array (PA) technology that controls the acoustic characteristics such as the refracted angle, focal distance and aperture without moving the probe. When compared to conventional ultrasonic testing (UT) methods, this technology opens a series of new possibilities such as:
- Multiple refracted angles and focal distances can be generated simultaneously by a single search unit.
- Ultrasonic beams can be electronically moved over the length of the PA probe without any mechanical movement.
- The probability of detection can be increased by using multiple ultrasonic beams.
- Automated or semi-automated inspection methods can be implemented more efficiently.
