    • Extrapolation of excavator main pump load spectrum based on threshold selection for principal component analysis

    • “In the field of time-domain extrapolation of load spectra, experts have proposed a multi criteria threshold selection method based on principal component analysis, which effectively solves the problem of high sensitivity and low accuracy in threshold selection and provides a solution for time-domain extrapolation of load spectra.”
