Torsional parametric oscillations in wires
European Journal of Physics, 1990Quite some time ago, Melde (experimentally) and Rayleigh (theoretically) investigated one of the earliest examples of a parametric oscillator. They showed that a periodic modulation of a string's length (longitudinal excitation) gives rise to transverse string vibrations. A similar effect is observed when a periodic torsional modulation is applied to a

Nonlinear oscillations of the torsion oscillator with impact masses
1997This paper deals with nonlinear oscillations of the torsion oscillator with reciprocal rigidly connected impact masses. It is assumed that two impulses occur at one interval of the disturbing torsion moment. The asymptotic Krilow-Bogolyubov-Mitropolyskiy method is applied, along with the stereomechanical impact theory for the inclusion of impact ...
