Abstract. The movement character of linear oscillators with different natural frequencies under harmonic momenta is studied. The periods of oscillators forced vibrations and conditions for vibrational amplitude increase (in damping absence) are determined. It is ascertained that short momenta effectively excite low-frequency oscillators, and long momenta – high-frequency oscillators. It is shown that oscillators with different natural frequencies under harmonic momenta can simultaneously come to the state of rest (at zero starting conditions), and then the process of uncoupled vibrations will repeat.
Key words and phrases: возбуждение линейных осцилляторов периодическими импульсами, периодические вынужденные колебания, нарастающая амплитуда колебаний, колебания несвязанных осцилляторов, linear oscillators excitation with recurrent pulses, periodic forced vibrations, increas
