Filed: 1990-09-17
Abstract: PURPOSE: To damp the vibration of a tubular member by fitting a cable tip member to the first ends of a plurality of flexible cables capable of absorbing the vibrational energy of a tube, and providing cable end fittings at the second ends. CONSTITUTION: A plurality of flexible braided cables 210 capable of absorbing vibrational energy of a tube are provided with first ends 280 and second ends 290. A rigid cable tip member 310 surrounds the first ends 280, and rigid cable end fittings 410 surround the second ends 290.
