Computer robust parameter design of surface eddy current probes. Developing software design of numerical experiments creating

Abstract

In this study, the initial stage of computer robust parameter design of a surface eddy-current probe on the example of a thickness gauge was performed using the integration of the Taguchi method with numerical modeling. It involves the selection of controllable design and operating parameters of the probe and uncontrollable noise parameters. The software for calculating the output signal of the thickness gauge was created and verified. In order to establish the boundary values of the factors, numerical modeling was performed, which allowed to obtain graphical dependencies of the change in the output signal of the probe on the variation of the selected factors. Based on the orthogonal arrays, taking into account the selected factors, a design of numerical experiments was created that allows creating robust parameter design using the developed software. Without eliminating the real causes of interference in the formation of the probe output signal, it ensures the selection of a rational variant of the set of its design and operating parameters, which implements the minimum variability of the probe response to noise factors at the initial design stage.
