Publication: Publication Date: 1 August 2019Testing Method:

The finite element method (FEM) is adopted for analyzing the sound field and setting the testing parameters of one-dimensional linear phased array testing. First, FEM models with high accuracy and efficiency are achieved by optimizing the modeling parameters. Second, the influences of the focusing sound field, such as inter-element pitch, element width, and element combination, are revealed based on the models. Ultimately, the finite element model of the phased array testing is verified by the experiment, and then, the element combination for a block of superalloy GH901 is decided according to the simulation. The experimental results show that a better resolution and lower distortion of the testing image can be achieved as the result of the finite element models. The combination of fewer elements is good for near-surface resolution, but the number of the combined elements should be increased with the increase of the focus depth. Thus, the simulation model can be used to analyze the sound field of phased array testing, which is also helpful for guiding practical application.
