    Abstract: 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.

    Abstract: A vibration isolator comprising: a piston (1605) resiliently disposed within a housing (1603) with a first set of seals (1607); a mount plate (1609) configured for attachment to a vibrating body, the piston being connected to the mount plate; an upper fluid chamber (1611) and a lower fluid chamber (1613), each being defined by the housing, the piston, and the first set of seals; a tuning port (1620) for fluid communication between the upper fluid chamber and the lower fluid chamber; a tuning fluid disposed within the upper fluid chamber, the lower fluid chamber, and the tuning port; and a piezo piston (1619) resiliently disposed with the housing, the piezo piston being configured to be driven by at least two piezoceramic actuators (1623).

    Abstract translation: 图8所示的可调振动隔离器具有有源调谐元件，该有源调谐元件具有外壳，流体室和至少一个调谐端口。 活塞弹性地设置在壳体内。 振动隔离流体设置在流体腔室和调谐端口内。 可调振动隔离器可以采用固体调谐质量方法或液体调谐质量方法。 主动振动元件优选为固态致动器。
