摘要

•Recursive analytic based active sensing method is employed to monitor bolt looseness.•The multi-bolt looseness degree could be quantified by recursive entropy.•Recursive entropy effectively eliminates the energy saturation and fluctuation.•The phase trajectory and recurrence plots method could position the bolt looseness.
