Response of a Parametrically Excited System to a Nonstationary Excitation [PDF]

open access: yesJournal of Vibration and Control, 1993
The response of a single-degree-of-freedom system to a nonstationary excitation is investigated by using the method of multiple scales as well as analog- and digital-computer simulations. The unexcited system has one focus and two saddle points. The system can be used to model rolling of ships in head or follower seas.
