    • 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.
    • 双串联阻尼器包括流体阻尼器部分和弹性阻尼器部分。 流体阻尼器部分包括第一壳体,第一连接构件和联接到第一连接构件的活塞。 活塞将第一壳体的内部分成第一流体室和第二流体室。 活塞在活塞中具有流体通道,流体通道构造成在第一流体室和第二流体室之间提供流体连通。 弹性阻尼器部分包括第二壳体,联接到第二壳体的第二连接构件以及在第一壳体和第二壳体之间的弹性体。 当引导/滞后力被引入双重串联阻尼器时,流体阻尼器部分刚性地运动,使得弹性阻尼器部分阻尼引导/滞后振荡。
