US5356123A Elastic mount having fluid chamber partially defined by oscillating plate actuated by electrostrictive/magnetostrictive element 失效
弹性底座，其具有由电致伸缩/磁致伸缩元件致动的振动板部分限定的流体室

Elastic mount having fluid chamber partially defined by oscillating plate actuated by electrostrictive/magnetostrictive element
摘要：
A fluid-filled elastic mount wherein an elastic body elastically connecting a first and a second support partially defines a fluid chamber filled with a non-compressible fluid. The elastic mount further includes an oscillating plate which partially defines the fluid chamber and which is supported by the second support such that the oscillating plate is displaceable relative to the second support, and an electrostrictive/magnetostrictive element for oscillating the oscillating plate to thereby change a pressure of the fluid in the fluid chamber. The second support has a small-diameter cylindrical portion to which the elastic body is secured, and a large-diameter cylindrical portion in which the oscillating plate having a large surface area is accommodated. The electrostrictive/magnetostrictive element is interposed between the oscillating plate and a support member fixed to the second support.
摘要（中）：

流体填充的弹性座，其中弹性地连接第一和第二支撑件的弹性体部分地限定填充有不可压缩流体的流体室。 弹性安装件还包括一个摆动板，该振动板部分地限定流体室并且由第二支撑件支撑，使得振动板相对于第二支撑件可移位;以及电致伸缩/磁致伸缩元件，用于振荡振荡板从而改变 流体腔中流体的压力。 第二支撑件具有固定有弹性体的小直径圆筒部，容纳有大面积的摆动板的大径圆筒部。 电致伸缩/磁致伸缩元件插入振荡板和固定到第二支撑件的支撑构件之间。
