基于振动传递率的层合板局部脱层损伤识别研究
Research on Identification of Local Delamination Damage in Laminated Panels Based on Vibration Transmission Rate
摘要
Abstract
To simply and accurately measure the location of local lamination damage in lamina struc-ture,a local damage identification method is proposed based on the sparseness of vibration transfer rate function.This paper designs the experimental scheme of GFRP laminate vibration and collects the multi-point acceleration response data,and builds the vibration transfer rate function map using the data,and se-lects the local steady state frequency band and sparse the L1 norm,and analyzes the effects of different peeling positions and peeling degree on peeling damage index TD.The results show that the distribution of the damage identification index TD is in good agreement with the distribution of the actual specimen lamel-lination damage,and the lamination position and damage identification can have good engineering applica-tion value.关键词
