Research Progress of Hole-Edge Damage Quantification Technology for Bolted Joints
摘要
Abstract
Bolted joints are characterized by complex hole-edge failure modes and multiple damage parameters,where the monitorability of multi-characteristic parameters for deep damage under different failure modes remains a bottleneck in hole-edge damage monitoring.This paper reviews quantitative monitoring methods for hole-edge damage in bolted joints,highlighting the development of a multi-parameter quantitative monitoring technique based on embedded eddy current sensor arrays and its application progress in metallic and composite bolted joints.Compared with other methods,this technology establishes an eddy current field fully covering bolt holes in multi-layer overlapping plates,and solves the challenges of monitoring and inversion for hole-edge damage angle,depth,and length/area through mapping relationships between multi-sensor signals from eddy current coil arrays and damage parameters.To meet the demand for composite bolts,a preparation method for composite smart bolts with highly compatible embedded eddy current sensors is proposed,enabling self-diagnosis of hole-edge damage without compromising bolt mechanical properties.It provides new theoretical methods and technical approaches to ensure aircraft structural integrity and enhance structural design capabilities.关键词
