NettetThe Joint Time Frequency Analysis function allows users to analyze time waveform data and then show frequency content changes versus time. CALL (844) 837-8797 … Nettet10. jun. 2024 · ABSTRACT. Many time-frequency analysis methods, such as Short Time Fourier Transform (STFT), Wavelet Transform (WT), Hilbert-Huang Transform (HHT), and the newly developed method -Short Time Prony Transform (STPT), have been developed to investigate the time-varying performance of structures. In this paper, … NettetPlanetary gearbox vibration signals have strong modulation features due to the amplitude modulation and frequency modulation (AM-FM) effect of gear faults, as well as the amplitude modulation (AM) effect of time-varying vibration transfer paths, on gear meshing vibrations. This results in an involute sidebands structure in Fourier spectrum, possibly … pistola k100
