Multimodal vibro-acoustic bearing-fault diagnosis method based on channel fusion and the VACF-CNN model
Keqin Ding, An Sun, Min Cao, Chuanjia Yao, Xifan Li
Abstract Bearing-fault diagnosis based on single-modal signals is often constrained by incomplete fault information, whereas existing multimodal fusion methods often suffer from feature redundancy and a heavy preprocessing burden. To overcome these limitations, a vibro-acoustic c…
