Abstract:
1. A mechanical self-tuning vibration absorber system for a variable vibrating body having a body vibration with a varying frequency, said body vibration having a vibration direction, said mechanical self-tuning vibration absorber system attached to said variable vibrating body, said mechanical self-tuning vibration absorber system having a first absorber unit with a first damping ratio and a second absorber unit with a second damping ratio, said second absorber second damping ratio different from said first absorber first damping ratio, said first absorber unit connected to said second absorber unit wherein said connected first absorber unit and said second absorber unit mechanically walk in a first tuning direction to a low tuned position when said variable vibrating body vibration varying frequency changes to a lower frequency, said first tuning direction perpendicular to said vibration direction, and in a second tuning direction to a high tuned position when said variable vibrating body vibration varying frequency changes to a higher frequency, said second tuning direction perpendicular to said vibration direction.
