Time-reassigned synchrosqueezing transform: The algorithm and its applications in mechanical signal processing

•We propose TSST for impulsive-like signal whose TF ridge is nearly vertical.•TSST is reassigned in time direction and enables mode reconstruction.•We compare the SST and TSST and present respective application scope.•TSST is applied in lamb wave simulation and rub-impact fault diagnosis. Synchrosqu...
