RISNonstationary Oscillation of a Rotating Shaft With Nonlinear Spring Characteristics During Acceleration Through a Major Critical Speed (A Discussion by the Asymptotic Method and the Complex-FFT Method)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonstationary oscillations during acceleration through a major critical speed of a rotating shaft with nonlinear spring characteristics are discussed. First, the first approximate solutions of ...
Nonlinear Forced Oscillations Caused by Quartic Nonlinearity in a Rotating Shaft System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with nonlinear forced oscillations in a rotating shaft system which are caused by quartic nonlinearity in a restoring force. These oscillations are theoretically analyzed by ...
