摘要： An epicyclic gearbox is configured to transfer rotational motion between a first rotating component and a second rotating component of the gas turbine engine. The gearbox includes a centrally located sun gear, two or more planet gears circumscribing the sun gear, and a ring gear circumscribing the plurality of planet gears. The gearbox is configured such that the sun gear is drivingly coupled to the first rotating component, such that rotation of the sun gear causes rotation of each planet gear, and such that the ring gear rotates relative to the plurality of planet gears. The gearbox includes one or more shape memory alloy dampers provided in association with the sun gear, the ring gear, and/or the plurality of planet gears. The shape memory alloy damper(s) is configured in order to reduce vibrations transferred through the epicyclic gearbox to the frame, the first rotating component, and/or the second rotating component.

摘要： A rotary damper (10) includes a stationary member (12) and a rotating member (14) provided within the stationary member (12) so that a gap (16) is defined between the rotating member (14) and the stationary member (12). The rotating member (14) further includes a central shaft (18) provided therein. A viscous fluid (19) is provided in the gap (16) and has an associated shear that provides a velocity damping within the gap (16). A differential growth in the gap (16) caused by temperature variation compensates for temperature damping variation. A compliant member (20) is provided within the stationary member (12) for providing thermal compensation. A secondary hermetic seal (26) is provided on the stationary member (12) for permitting limited rotation, defining a vacuum environment and preventing viscous fluid leakage to an external environment.

摘要： On an outside of a damper main body of an inverted type of vehicular damper, a pressure casing of a cylindrical shape which is connected to a damper rod is provided in a manner movable up and down. A pressure chamber for containing therein a pressure medium which varies between a liquid phase and a gaseous phase is formed between the damper main body and the pressure casing. An electric heater to heat and evaporate the pressure medium inside the pressure chamber is provided. Electric charging to the electric heater is controlled by a vehicle height detection switch which is attached to the damper rod or the like.

摘要： The present invention relates to a vibration absorber in which an absorber end mass is coupled to a primary mass by means of a cantilevered beam, wherein at least a portion of the beam comprises a shape memory alloy (SMA). Preferably, the end mass is coupled to the primary mass with several discrete SMA wires which may be individually heated. When each of the SMA wires is heated above a predetermined temperature, the SMA material undergoes a phase change which results in a change in the stiffness of the SMA wire. Heating of the various wires in various combinations allows the operational frequency of the absorber to be actively tuned. The frequency of the absorber may therefore be tuned to closely match the current vibrational frequency of the primary mass, thereby allowing the absorber to be adaptively tuned to the frequency of the primary mass in a simple and straightforward manner.
摘要翻译：吸振器技术领域本发明涉及一种吸振器，其中吸收体质量块通过悬臂梁联接到初级质量块，其中梁的至少一部分包括形状记忆合金（SMA）。优选地，末端质量体与几个离散的SMA线连接到主质量块，可以单独加热。当每根SMA线被加热到高于预定温度时，SMA材料经历相变，导致SMA线刚度的变化。以各种组合加热各种电线可以使吸收体的工作频率得到主动调节。因此，可以调节吸收器的频率以紧密地匹配初级质量块的当前振动频率，从而允许吸收器以简单和直接的方式自适应地调谐到主质量的频率。
