摘要

提出了一种提高表面涡流电导率仪信噪比信噪比的方法，用于移动平面金属非磁性（介质、顺磁性）和弱磁性测试对象。这是由于田口的稳健参数设计探针与矩形正交线圈，这有助于确定他们的最佳修改使用实验理论的设计。给出的具体实例证明了该方法的有效性，该方法在提高信噪比的同时，还降低了输出信号的方差。为了创建田口实验设计，使用了移动测试对象上探针的磁动力学模型，并使用了正交阵列。通过计算机数值计算验证了所建立的涡流探头最优修正的可靠性。通过方差方差分析，建立了探头设计参数和工作参数对其信号特性影响程度的层次关系。在此基础上，制定了制造其结构精度的技术要求和保持探头工作模式稳定性的条件。

Robust parameter design of eddy current meters for the electrical conductivity of materials and products of considerable thickness

A method for increasing the signal-to-noise ratio SNR of surface eddy current conductivity meters for moving planar metal nonmagnetic (dia-, paramagnetic) and weakly magnetic test objects is proposed. This was achieved because of Taguchi’s robust parameter design of probes with rectangular orthogonal coils, which helped determine their optimal modifications using the design of experiments theory. The given specific examples demonstrate the effectiveness of the method, which, in addition to increasing the SNR, also simultaneously reduces the variance of the output signal. To create a Taguchi design of experiments, a magnetodynamic model of the probe over a moving test object was used, along with the use of orthogonal arrays. The reliability of the found optimal modifications of eddy-current probes is proved by confirming computer numerical calculations. The hierarchy of the degree of influence of the design and operating parameters of probes on their signal characteristics was established by means of variance ANOVA analysis. On this basis, the technical requirements for the accuracy of manufacturing their structures and the conditions for maintaining the stability of the probe‘s operating modes are formulated.
