    • A system and method of active vibration control of an electro-mechanically cooled device is disclosed. A cryogenic cooling system is located within an environment. The cooling system is characterized by a vibration transfer function, which requires vibration transfer function coefficients. A vibration controller generates the vibration transfer function coefficients in response to various triggering events. The environments may differ by mounting apparatus, by proximity to vibration generating devices, or by temperature. The triggering event may be powering on the cooling system, reaching an operating temperature, or a reset action. A counterbalance responds to a drive signal generated by the vibration controller, based on the vibration signal and the vibration transfer function, which adjusts vibrations. The method first places a cryogenic cooling system within a first environment and then generates a first set of vibration transfer function coefficients, for a vibration transfer function of the cooling system. Next, the cryogenic cooling system is placed within a second environment and a second set of vibration transfer function coefficients are generated. Then, a counterbalance is driven, based on the vibration transfer function, to reduce vibrations received by a vibration sensitive element.
    • 公开了一种电机械冷却装置主动振动控制的系统和方法。 低温冷却系统位于环境中。 冷却系统的特征在于振动传递函数,这需要振动传递函数系数。 振动控制器响应各种触发事件产生振动传递函数系数。 环境可能因安装设备,靠近振动发生设备或温度而不同。 触发事件可能会启动冷却系统,达到工作温度或复位动作。 基于调节振动的振动信号和振动传递函数,平衡响应由振动控制器产生的驱动信号。 该方法首先将低温冷却系统放置在第一环境内,然后产生用于冷却系统的振动传递函数的第一组振动传递函数系数。 接下来,将低温冷却系统放置在第二环境内,并产生第二组振动传递函数系数。 然后,基于振动传递功能驱动平衡,以减少振动敏感元件所接收的振动。

    • The invention disclosed is a compact, high efficiency, smart material element driven hydraulic pump comprising a diaphragm, a face plate coupled to and spanning across the diaphragm, and a smart material element. The diaphragm comprises on a first side a recess and a stiff face-seal surface surrounding the recess. On the second side of the diaphragm is a stiff center pedestal and a flexure means attached to the periphery of the center pedestal. The diaphragm and face plate coupled together form a chamber that is dynamically sealed by contact of the face-seal surface against the face plate and such chamber's compliance is primarily and effectively within the flexure means within the diaphragm. A smart material element is positioned and constrained against the stiff center pedestal such that extension and contraction of the smart material element deforms the diaphragm such that the pumping chamber compresses and expands through compliance and deformation within the flexure means alone. In a preferred form the flexure means is comprised of two annular flexures and the recess is of conical edge shape such that the chamber flattens against the face plate to effect a broad, low profile pump chamber having negligible seal compliance and providing high volumetric efficiency.
    • 所公开的发明是一种紧凑,高效率,智能材料元件驱动的液压泵,其包括隔膜,耦合到横跨隔膜的跨越隔膜的面板和智能材料元件。 隔膜在第一侧上包括凹部和围绕凹部的刚性面密封表面。 在隔膜的第二侧是刚性的中心基座和附接到中心支架的周边的挠曲装置。 联接在一起的隔膜和面板形成通过面密封表面与面板的接触动态密封的室,并且这种室的顺从性主要且有效地在隔膜内的挠曲装置内。 智能材料元件被定位并限制在刚性中心基座上,使得智能材料元件的延伸和收缩使隔膜变形,使得泵送室在柔性单元内仅通过柔性和变形来压缩和膨胀。 在优选形式中,挠曲装置包括两个环形弯曲部,并且凹部具有锥形边缘形状,使得该腔室平坦地抵靠面板,以实现具有可忽略的密封顺应性并提供高体积效率的宽而低的轮廓泵室。
