摘要： A double pumper mount useful as a front mount for an aircraft engine. A pair of fluid chambers are selectively interconnectable by one of a plurality of inertia tracks by use of an adjustable cylindrical member which has the tracks formed as generally helical grooves extending about the periphery of the cylindrical member. These inertia tracks have different flow characteristics so as to produce differing notch frequencies so as to attenuate different vibrational frequencies. A second embodiment has a single inertia track whose length can be altered by rotating the cylindrical member to change the point at which the ingress/egress port of the fluid chamber engages the circumferential portion of the inertia track.

摘要： A mounting (20) which provides low vertical and lateral spring rates for excellent lateral and vertical vibration isolation yet provides a high roll stiffness for reacting torsional moments, while reducing isolator complexity and eliminating the need for a yoke or hanger. The mounting (20) includes a top member (34), a first arm (26) and a second arm (28) which are flexibly interleaved or attached. The first arm (26) is attached to a top member (34) by way of a pivot which can be a spring (30), the second arm (28) is also attached to the top member (34) by another pivot which can be a spring (32), and a third spring (36) attaches the arms (26) and (28) to each other. The arms (26) and (28) also attach to the supported member (22) preferably at their respective outboard ends (38), or at least one intermediate link can be used. The arms (26) and (28) are stiffly interconnected to one another, yet flexibly connected to a top member (34), such that relative vertical movement between the arms (26) and (28) is restricted. Thus a high roll stiffness is provided, yet allowing movement of the arms (26) and (28) as a unit for providing vertical and lateral isolation. One embodiment of the mounting (20) improves further over the related mountings by localizing the lateral elastic center of the mounting (20) towards the center of gravity (CG) of the supported member (22) such that side loads applied to the supported member (22) result in lateral translation and limited rotation of the (CG) of supported member (22).
摘要翻译：一种安装（20），提供低垂直和侧向弹簧刚度以获得优异的横向和纵向振动隔离，同时提供高扭矩刚度用于反作用力矩，同时减少隔离器的复杂性，并消除对轭架或吊架的需要。安装件（20）包括柔性地交错或连接的顶部构件（34），第一臂（26）和第二臂（28）。第一臂（26）通过可以是弹簧（30）的枢轴附接到顶部构件（34），第二臂（28）也通过另一枢轴连接到顶部构件（34）作为弹簧（32），第三弹簧（36）将臂（26）和（28）彼此附接。臂（26）和（28）也优选地在其相应的外侧端（38）附接到支撑构件（22），或者可以使用至少一个中间连杆。臂（26）和（28）彼此刚性互连，但是柔性地连接到顶部构件（34），使得臂（26）和（28）之间的相对垂直运动受到限制。因此，提供了高滚动刚度，但是允许臂（26）和（28）作为用于提供垂直和横向隔离的单元的移动。安装件（20）的一个实施例通过将安装件（20）的侧向弹性中心朝向被支撑构件（22）的重心（CG）定位而使相关安装件进一步改进，使得施加到被支撑构件（22）导致支撑构件（22）的（CG）的横向平移和有限的旋转。

摘要： A tuned vibration absorber includes a mounting plate having at least two, and alternatively four, mounting holes in spaced relationship from a longitudinal center axis of the plate. An elastomeric spring is bonded to the mounting plate. A main tuning mass is bonded to the elastomeric spring opposite the mounting plate, and fine tuning masses are riveted directly onto the main tuning mass. The elastomeric spring and main mass both have a rectangular profile to maintain a low profile height from the mounting plate. A cover is formed of a single sheet of metal bent to form a rectangular box with one open side. The cover includes mounting flanges with holes that align with the mounting holes on the mounting plate. For mounting the vibration absorber on a stiffening ring of an aircraft frame, a spacing plate is positionable between a portion of the mounting plate and the stiffening rib of an aircraft frame, and adjacent to an overlapping secondary stiffening ring to provide a flat mounting surface.
