摘要： The bidirectional valve assembly provides for selection of retraction and extension damping characteristics which can accommodate relatively large separation of damping curves. Two cooperable valve discs or ring members are provided which function in unison to resist fluid flow in a first fluid flow direction, while a single one of the valve ring members functions primarily to resist fluid flow in the other direction. In a first embodiment, one of the two cooperable valve ring members comprises a compliant retainer or fulcrum against which the other valve ring member moves in unison therewith to produce relatively low damping in retraction. The other valve ring member moves alone in extension to produce relatively high damping. In an alternative embodiment, the two cooperable valve ring members are superimposed and move in unison during extension, as dictated by their combined stiffness. In retraction, fluid passes through openings in one of the valve ring members for contact with and movement of the other, relatively compliant valve ring member.

摘要： An Active Vibration Absorber assembly (20) including a casing (24), a first tuning mass (32) supported relative to the casing (24) which is actively vibratable by a force generator (40) in a first direction (along an A--A axis), a second tuning mass (32') supported relative to said casing (24) which is actively vibratable by a force generator (40') in a second direction (along axis B--B) generally orthogonal to the first direction, and a flexible member (26) flexibly supporting the casing (24). In a first embodiment, the tuning masses (32, 32') are vibratable by a magnet and coil assembly within shakers (25, 25') and the flexible member (26) is a beam. In other embodiments, multiple beams are employed to restrict the vibration of casing (24) to substantially planar motion. The AVA assembly (20) finds application in Active Structural Control (ASC) systems for actively canceling vibration or noise in vehicle cabins (example: automobiles, aircraft).

摘要： An active mount for fixed wing applications. One aspect of the invention provides decoupling of two tones which are close in frequency by positioning the mount actuators and error sensors in the primary transmission path of the disturbance vibration and by providing adequate spatial separation between the two sets of error sensors to reduce or eliminate cross-coupling of the signals. Another aspect of the invention utilizes orthogonally positioned actuators with corresponding actuators of paired mounts being focalized for each engine.

摘要： An improved method and means for control and accomplishment of semi-active damper means transition between high damping and low damping states is provided which takes advantage of the available inherent dynamic fluid pressure forces produced by the condition of motion between supported and supporting members. Deferral or delay of damper state transitions to avoid force discontinuities or system noise is accomplished mechanically, or automatically internal to the structure of the adjustable valve means. The delay of damper state transition from high to low and low to high damping is accomplished independent of the particular control policy utilized until the fluid pressure differential across the valve ring members is a preselected low value. Commanded valve switching and motion condition sensing requirements are also minimized by reversible check valve means. Damper state transitions normally required based on a sign change in relative velocity are accomplished without actuated change in valve ring position by one of the inner and outer valve rings (in the "off" state) which floats between flow permitting and flow restricting positions dependent upon the direction of fluid flow through the piston.
摘要翻译：提供了一种用于控制和实现半主动阻尼器的改进方法和装置，其在高阻尼和低阻尼状态之间的过渡，其利用由支撑构件和支撑构件之间的运动状态产生的可用的固有动态流体压力。缓冲器状态转换的延迟或延迟以避免力中断或系统噪声机械地实现，或者在可调节阀装置的结构内部自动实现。阻尼器状态从高到低和高阻尼转变的延迟是独立于所使用的特定控制策略而实现的，直到阀环构件上的流体压力差是预选的低值。指令阀切换和运动状态检测要求也通过可逆止回阀装置最小化。基于相对速度的符号变化通常需要的阻尼器状态转换通过内阀和外阀之间的一个（处于“关”状态）而在阀环位置上的动作变化下实现，该阀环位于依赖于流动允许和限流位置之间浮动流体流过活塞的方向。

摘要： Operation of a continuously variable semiactive damper of the system is modified so as to reduce generation in the system of undesirable shocks and noise. The modifications include delaying some or all of the changes in the on/off states of the damper, and/or limiting the rate and/or extent of changes in the damping coefficient of the damper at certain of the times when the damper is in an on state.
