Abstract
- Objective Riveting quality issues cannot be visually judged. By employing the far-field eddy current testing method, internal quality defects in riveted structural components can be detected, providing theoretical and technical support for product quality inspection. Method Riveting quality inspection and classification of clearance types are conducted without damaging the workpiece. Far-field eddy current testing experiments are carried out for the intermediate plate clearance and rivet hole clearance of rail vehicle riveted structural components respectively. Testing research on metro vehicle anti-roll torsion bar seats riveted to the body frame side beams is also conducted. Result & Conclusion From the results of the three sets of experiments, it is evident that the range of phase angles can distinguish between rivet and hole clearances and plate clearances. The phase amplitude range for hole clearances is 60° to 90°, while for plate clearances, it is 0 to 10°.
