...M. Eissa; M. Kamel; A. T. El-Sayed An investigation into the passive vibration reduction of the nonlinear spring pendulum system, simulating the ship roll motion is presented. This leads to a four-degree-of-freedom (4-DOF) system subjected to multiparametric excitation forces. The two absorbers...

...Frederik J. Mostert; Izak M. Snyman; Marius Olivier An experimental technique is demonstrated whereby the dynamic deflection of a thin plate or combination of plates, impulsively loaded by the blast of an explosive charge, can be characterized. A blast pendulum measures the resulting impulse...

...V. A. Lubarda Upper bounds on Newton’s, Poisson’s, and energetic coefficients of normal restitution for the frictional impact of rigid pendulum against a fixed surface are derived, demonstrating that the upper bound on Newton’s coefficient is smaller than 1, while the upper bound on Poisson’s...

..., for the first time, a comprehensive set of experimentally obtained contact force waveforms during oblique elastic impact for a range of initial velocities and incidence angles. The experimental apparatus employed in this study was a simple pendulum consisting of a spherical steel striker suspended from a steel...

...P. Gallina; A. Trevisani This paper introduces a non-time-based control scheme for active position and vibration control of two-degree-of-freedom systems by applying it to the path-tracking and swing control of a system composed of a trolley and a simple pendulum. The basic idea behind...

...R. Bhattacharyya, Mem. ASME, Associate Professor, The stability of motion of a nonlinear neo-Hookean rubber spring pendulum under a special type of support oscillation is studied. The small swing motion is described by a Mathieu-Hill equation, corresponding stability curves for which are generated...
