A Rectangular Flexible Eddy Current Array Sensor for Detecting Cracks on the Curved Surface of Engineering Vehicle Hubs
Source abstract
Abstract
Before engineering vehicle hubs are put into official use, it is crucial to conduct safety inspections for cracks that may occur during the manufacturing process. This study proposes a rectangular flexible eddy current array sensor for detecting cracks on the curved surfaces of engineering vehicle hubs. The study begins with sensor design, proposing a quantitative analysis method for surface cracks on test samples based on the sensor’s structural characteristics. Through finite element simulation, the relationship between the sensor and the distribution of surface cracks on the sample is analyzed, revealing the correlation between the orientation angle of the sample cracks and the changes in the induced demodulated voltage characteristics of the receiving coil. Experiments conducted on steel plates demonstrated the feasibility of this method for quantifying crack length and orientation angle. Moreover, in the wheel hub surface crack detection experiment, this sensor also demonstrated certain detection capabilities.
