[Also in Divisions F2 and H2] A vibration damper for a cable 6 has inertia members 8 of different masses and different moments of inertia about transverse axes through their centres of gravity carried on springs 3 projecting different distances L1, L2 from the clamp 2. The ratio of the masses of members 8 may be less than 0.875 or greater than 1.15, and the ratio L1 may be less than 0.93 or greater than 1.08. |
