EXPERIMENTAL VERIFICATION OF RESONANCE BEHAVIOUR OF A DAMPED SPHERICAL PENDULUM
Abstract eng: heoretical, experimental and numerical analysis of a spherical pendulum is carried out. The stability of the respons e in a vertical plane is analysed in the theoretically predicted resonance region. Mathematical model respects the non-linear character of the pendulum and allows to introduce asymmetrical damping. Experimental analysis is performed using a special experimental frame where a pendulum is supported by the Cardan joint and damped by two magnetic units. Uni-directional harmonic excitation is applied to the system. These units are able to reproduce linear viscous damping independently in both principal response components. Measured data are compared to theoret ical and numerical results.
