飞机铆接结构缺陷的远场涡流检测技术研究
Research on Remote Field Eddy Current Technique Applied to Inspect Riveted Structure
摘要
Abstract
The detection and evaluation of defects in aircraft fuselage riveted structure is one of the most difficult problem in the field of nondestructive testing. Remote field eddy current testing is not limited by the skin effect and can be used to detect the defects in large thick plate. In this work, remote field eddy current phenomenon is a-chieved in the non-magnetic metal plate after designing the excitating coil of the probe with multilayer shielding structure. The probe can be used to detect defects in riveted structure by rotary scanning method. Simulation results show that the phase has a minimal value as the detection coil is just at the top of the defect,and there is a linear re-lationship between the phase and the depth of the defect. Research result verifies the feasibility of remote field eddy current testing in riveted structures.关键词
