METHOD AND APPARATUS FOR IMPROVED VIBRATION ISOLATION

A tunable vibration isolator (451, 551, 651, 681, 691, 721, 801, 901, 973) with active tuning elements (473, 475, 573, 673, 675, 689, 705, 707, 745, 74 7, 747, 819a, 819b) having a housing which defines fluid chambers. A piston (45 5, 555, 655, 695, 725, 805, 970) is disposed within the housing. A v...

More Information
Summary:A tunable vibration isolator (451, 551, 651, 681, 691, 721, 801, 901, 973) with active tuning elements (473, 475, 573, 673, 675, 689, 705, 707, 745, 74 7, 747, 819a, 819b) having a housing which defines fluid chambers. A piston (45 5, 555, 655, 695, 725, 805, 970) is disposed within the housing. A vibration isolation fluid is disposed within the fluid chambers. A passage (463, 563, 663, 735, 881, 904) having a predetermined diameter extends through the pist on to permit the vibration isolation fluid to flow from one fluid chamber to th e other. The tunable vibration isolator may employ either a solid tuning mass approach or a liquid tuning mass approach. In either case, active tuning elements, or actuators, are disposed in the fluid chambers to selectively tu ne the vibration isolator.
