Abstract

The present work concerns the study of the effect of variation of the thickness of 2D cylindrical test-piece and lift-off (the air gap between the sensor and the test-piece) on the sensor response in case of transient source current. The coupled circuit’s method employed is based on the mutual’s inductances calculation and with the association to Kirchhoff laws it yields to a transient algebraic equations system which is solved at each time step. The method is applied to the study of the pulsed eddy currents in cylindrical and axisymmetric device with electrical conductivity and geometrical dimensions variations.

耦合电路法应用于脉冲涡流无损检测问题

本研究涉及在瞬态源电流情况下，二维圆柱形测试件厚度和升程（传感器与测试件之间的空气间隙）的变化对传感器响应的影响。所采用的耦合电路方法以互感计算为基础，并与基尔霍夫定律相关联，从而得到一个瞬态代数方程系统，并在每个时间步长上求解。该方法被应用于研究具有导电性和几何尺寸变化的圆柱形和轴对称装置中的脉冲涡流。
