Experimental Validation of a Phased Array Ultrasonic Testing Probe Model and Sound Field Optimization
Licentiate thesis, 2020
In the current work, the main purpose is to further validate the phased array probe model in simSUNDT by comparing simulation results with corresponding experiments. An experimental platform is built with the intention to fully control the operation conditions and the set of testing results. Well-deﬁned artiﬁcial defects in test specimens are considered in both simulations and experiments. Comparisons in the end validate the current phased array probe model and could be treated as an alternative to experiments.
With the aid of this validated probe model, optimization of the generated sound ﬁeld from a phased array probe is then conducted. The optimization aims at searching for a proper combination of main beam angle and focus distance of the probe at this stage, so that the echo amplitude from a certain defect reaches its potential maximum.
