Active Vertical Vibration Control of Railway Vehicle Carbody with Variable Cross-Section Using Secondary and Piezoelectric Actuators

The longitudinal non-uniformities in mass and stiffness distributions of railway vehicle carbodies, caused by doors, windows, and equipment compartments, significantly affect elastic vibrations and ride comfort. This paper establishes a vertical elastic vibration model based on the Euler–Bernoulli beam theory for varia...

A time-frequency method based on novel oddsymmetric window functions for mechanical equipment fault diagnosis

Under time-varying operating conditions, signals generated by mechanical equipment usually exhibit strong non-stationarity, frequency-modulation and amplitude-modulation (FM-AM), and contamination by background noise. These characteristics pose three main challenges for time-frequency analysis (TFA): the instantaneou...
