Electromagnetic Field Simulation in Technical Diagnostics

Abstract. An information diagnostic system is currently being developed. The system is based on electromagnetic non-destructive testing and uses a matrix magnetic converter for revealing flaws and forecasting the reliability of machines and mechanisms. The considered algorithm, which analyses magnetic nondestructive testing results, uses a dynamic type matrix magnetic transducer. To estimate crack parameters topography of magnetic leakage fields were explored. The method of finite elements is used to study the topography of the magnetic leakage field of flaws. A database has been formed for flaw type recognition, i.e. reconstruction of their form, size and position relative to weld seam. The purpose of this work is the creation of algorithm, allowing to obtain information on the topography of a magnetic field, and to optimize the speed of recognition of flaw parameters. New methods and algorithms will be developed to perform magnetic non-destructive testing and estimate the degree of danger caused by flaws to machine usage and design.
