Abstract
This paper presents a flaw inspection method based on eddy current effect, by comparison of environment analysis and inspection methods for the high-speed train bogie surface flaw. It designed a testing physical prototype and a reasonable control system which was based on eddy current inspection bogie surface flaw, what’s more, it made use of restraining lift-off effect in testing two times, and the result of experiment indicated that method which tested bogie surface flaw was feasible and effective by digital monitor. The method will offer a guarantee for moving of the high-speed train safely and comfortably, and establish a little base to inspect interior flaw and research farther.
