摘要： An assembly for providing flexure to a blade of a rotary blade system, the assembly including an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween. At least one of the upper and lower yoke surfaces having a layer of cushioning material positioned thereon and secured thereto. The layer of cushioning material extending along and following the general contour of yoke surface, and the layer of cushioning material directly contacting a support plate. Another embodiment is an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween and directly contacting the support plates wherein one of the curved surfaces is a non-circular arc that does not form part of the circumference of a circle.

摘要： A damper has a piston having an axis, an outer surface, and opposing ends. Elastomeric seals are in sealing contact with the outer surface of the piston, the seals being coaxial with the piston and limiting movement of the piston to a path along the axis of the piston. The seals also define fluid chambers adjacent the ends of the piston. A primary passage communicates the fluid chambers, and a selectively switchable valve for controls a flow of fluid from one of the chambers to another of the chambers through the primary passage. When the flow of fluid through the primary passage is permitted, movement of the piston is resisted by a first spring rate due to a shear force required to cause shear deflection of the seals. When the flow of fluid through the primary passage is restricted, movement of the piston is resisted by a second spring rate due to a fluid force required to cause bulging deflection of the seals.

摘要翻译： 阻尼器具有具有轴线，外表面和相对端的活塞。 弹性密封件与活塞的外表面密封接触，密封件与活塞同轴并且限制活塞沿着活塞轴线的路径运动。 密封件还限定了邻近活塞端部的流体室。 主要通道连通流体室，以及可选择地可切换的阀，用于控制通过主通道从一个室到另一个腔的流体流。 当允许通过主通道的流体流动时，活塞的运动由于需要剪切力而引起密封件的剪切偏转而抵抗第一弹簧刚度。 当通过主通道的流体流被限制时，活塞的运动由于需要使密封件凸起偏转所需的流体力而受到第二弹簧刚度的抵抗。

摘要： A vibration isolator for connecting a first body and a second body. The vibration isolator includes a housing having a first chamber, a second chamber, and a port connecting the first chamber to the second chamber and permitting fluid to flow between the first chamber and the second chamber. The first and second chambers and the port defining a fluid reservoir. The isolator including a gas-to-fluid accumulator in fluid communication with the fluid reservoir through a first one-way valve and a second one-way valve. The first one-way valve allows fluid to pass only from the fluid reservoir to the accumulator and the second one-way valve allows fluid to pass only from the accumulator to the fluid reservoir. At least one of the first and second one-way valves being preloaded to a predetermined force to permit fluid flow through the at least one-way valve only when fluid pressure exceeds the predetermined force.
