Ambiguousness and basins of attraction of the oscillator with soft impacts
Peterka, František ; Čipera, Stanislav
Dynamics of oscillators with soft impacts is characterized, in the comparison with oscillators with rigid impacts, by the existence of subharmonic impact motions, which should be excited by special motion initial conditions. The investigation of such motions was performed using the evaluation of basins of attraction of the oscillator motion regimes. New impact motions were ascertained and general conclusions were formulated.
Intermittency chaos of the impact oscillator
Peterka, František ; Čipera, Stanislav ; Kotera, T.
Chaotic motion of intermittency type of the impact oscillator appears near saddle-node stability boundaries of subharmonic motions with two impacts in the motion period. Chaotic motion arises due to an additional impact, which interrupts the process of instability. Intermitency chaos and its characteristics are explained in the paper.
