    Abstract: A hydraulic inertial vibration isolator (1) is connected between a vibrating body (3) and an isolated body (5). The vibration isolator (1) comprises a cylinder (7) which includes two chambers (35, 37) and a piston (9) therebetween. The chambers (35, 37) are connected by a tuning passage (31) in which a solid tuning slug (33) is slidably disposed. The chambers (35, 37) and the tuning passage (31) are filled with liquid. Bypass passages (57, 61) connecting the tuning passage (31) to the chambers (35, 37) allows the liquid pressure in the chambers (35, 37) to equalize when the amplitude of the tuning slug's oscillatory motion is sufficiently large, thereby limiting the tuning slug's amplitude. Dashpots (45, 47) axially disposed adjacent to either end of the tuning slug (33) act to damp excessive tuning slug motion and to bias the tuning slug (33) toward the center of the tuning passage (31). An electronic control system (69) is used to supply alternate current to magnetic coils (67) adjacent to the tuning slug (31), thereby matching the isolation frequency to the vibration frequency.

    Abstract: A vibration attenuation system for attenuating vibrations in a mast of an aircraft includes a weight attached to the mast but free to orbit about the mast. The weight can be comprised of one or more weight assemblies. Embodiments can include a single weight, or plural weight assemblies wherein each weight assembly can include a mechanical interconnecting mechanism so that each weight assembly receives feedback regarding the position and movement of one or more other weight assemblies. Each weight can be associated with a spring that urges the weight towards a neutral position. Rotation of the mast can cause the weight to orbit about the mast and self-excite such that the weight acts against the urging of the spring towards an attenuating position.

    Abstract translation: 用于衰减飞机的桅杆中的振动的减振系统包括附接到桅杆但可围绕桅杆自由绕轨道运动的重物。 重量可以由一个或多个重量组件组成。 实施例可以包括单个重量或多个重量组件，其中每个重量组件可以包括机械互连机构，使得每个重量组件接收关于一个或多个其他重量组件的位置和移动的反馈。 每个重量都可以与一个弹簧联系起来，这个弹簧将重量推向中立位置。 桅杆的转动可能导致重物在桅杆上绕轨道运动并自行激励，使得重物抵抗弹簧朝向衰减位置的推动而起作用。

    Abstract: A dual series damper includes a fluid damper portion and a elastomeric damper portion. The fluid damper portion includes a first housing, a first connection member, and a piston coupled to the first connection member. The piston divides an interior of the first housing into a first fluid chamber and a second fluid chamber. The piston has a fluid passage in the piston, the fluid passage being configured to provide fluid communication between the first fluid chamber and the second fluid chamber. The elastomeric damper portion includes a second housing, a second connection member coupled to the second housing, and an elastomer between the first housing and the second housing. When a lead/lag force is introduced to the dual series damper, the fluid damper portion behaves rigidly so that the elastomeric damper portion dampens the lead/lag oscillation.
