SUPPRESSION OF THE SELF-EXCITED VIBRATION OF THE PENDULUM SYSTEM INDUCED BY FLOW

Nabergoj R., Tondl A.
pages 193 - +10p., full text

In this contribution a pendulum system is treated. Here, not only the absorber damping effect is considered but also his application as an active tool for vibration suppression through parametric excitation. The parametric excitation is due to periodic stiffness variation of the elastic mounting of absorber mass. The positive effect of parametric excitation for suppressing self-excited vibration was discovered when analyzing interaction of self-excitation and parametric excitation, while the conditions for a full suppression self-excited vibration were formulated later on.
