Finite Element Modeling of the Magnetic Flux Distribution in the Primary Transducer of a Differential Magnetic Structuroscope
摘要
Abstract
Finite element modeling was performed to simulate the magnetic flux distribution in an H-shaped primary transducer of a magnetic structuroscope for the nondestructive assessment of residual austenite content in VNS-5 structural steel. The dependence of the magnetic induction in the center of the crossbar in the H-shaped magnetic core of the transducer on the difference in residual austenite content between samples was established. This dependence can be utilized for calibrating flaw detectors.
