Sub-resonant Response of a Mechanical System parametrically excited at its Resonant Frequency

IN the course of an attempt to improve the response of an inertial seismometer to very-low-frequency frame movements, it appeared worthwhile to investigate the response of a spring-mass system subjected to parametric excitation 1 . The parametric excitation or ‘pumping’ consisted of modulating the r...
