Reflection of short rectangular pulses in the ideal string attached to strongly nonlinear oscillator

摘要

The system under consideration is ideal elastic string attached to strongly nonlinear oscillator with cubic nonlinearity by two different ways-immediately and by weak linear spring. The reflection of short rectangular pulses from the oscillator is accompanied by excitation of vibrations. The type of mode excited determines the amount of energy transferred to the oscillator as well as the structure of the reflected wave. (C) 2000 Elsevier Science Ltd. All rights reserved.
