Nonlinear Free Vibration of a Spinning Tether
The Journal of the Astronautical Sciences, 1999 This paper considers nonlinear free vibration of a spinning tether. The tether is a part of a tethered satellite system spinning at a constant rate about its nominal longitudinal axis. Using Hamilton’s principle, the governing equations of motion are derived for the station-keeping phase retaining the nonlinear terms up to the third order.

Research on One-to-Two Internal Resonance of Sling and Beam of Suspension Sling–Beam System
Buildings, 2023 An approach is presented to investigate the 1:2 internal resonance of the sling and beam of a suspension sling–beam system. The beam was taken as the geometrically linear Euler beam, and the sling was considered to be geometrically nonlinear. The dynamic
