水下交流电磁场检测探头设计与结构优化
Design and Structural Optimization of Underwater ACFM Probe
摘要
Abstract
Alternating current field measurement(ACFM)is a new type of electromagnetic nondestructive detection technology,which can quickly and accurately detect the size of metal surface cracks.Focuses on the optimization of parameters for the magnetic yoke and detection coil of underwater ACFM probes,a simulation model for underwater ACFM is established by using the finite element software COMSOL.The U-shaped magnetic yoke parameters,such as the leg yoke height,upper yoke length,leg yoke length,leg yoke width,and the thickness of the upper yoke are analyzed and optimized through magnetic flux distortion variables.The relative position of the detection coil and the magnetic yoke is studied and the influence on the ACFM is analyzed.A reference size for the U-shaped magnetic yoke of the detection probe in underwater ACFM is given,the detection effect is better when the detection coil is located at the center of the yoke is proved,which provides a theoretical basis for the development and design of underwater pipeline detection probes.关键词
