    • A vibration damping device for mounting between two spaced portions of a vehicle. An inner metal cylindrical housing forms an internal piston chamber and is connected at one end to the vehicle, with a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. An outer housing surrounds a portion of the inner housing and forms a fluid duct or flow channel between fluid chambers formed on opposite sides of the piston. An electrode is mounted in the fluid duct for applying a voltage across the duct to affect the viscosity of an electrorheological (ER) fluid flowing therethrough to increase the damping force of the device. The electrode includes a plurality of circumferentially spaced splines and intervening grooves extending longitudinally along the fluid duct. The bottom portions of the grooves have a decreased electric field applied thereto than do the splines, providing bleed grooves or leak paths for the ER fluid to decrease the shear-rate of the fluid. The inner housing has elongated projections which extend into the grooves of the electrode to provide a more uniform electric field along the fluid duct to control the amount of leakage through the bleed grooves. A secondary electrode ground may be formed in the grooves to control the electric field in the bleed grooves.
    • 一种用于安装在车辆的两个间隔部分之间的减震装置。 内部金属圆柱形壳体形成内部活塞室,并且在一端连接到车辆,活塞可滑动地安装在活塞室内,连接到车辆的另一部分。 外部壳体围绕内部壳体的一部分并且在形成在活塞的相对侧上的流体室之间形成流体管道或流动通道。 电极安装在流体管道中,用于跨管道施加电压,以影响流过其中的电流变(ER)流体的粘度以增加装置的阻尼力。 电极包括沿着流体管道纵向延伸的多个周向间隔的花键和中间槽。 凹槽的底部比其花键具有减小的电场,为ER流体提供渗流槽或泄漏路径,以降低流体的剪切速率。 内壳体具有延伸到电极的凹槽中的细长突起,以沿着流体管道提供更均匀的电场,以控制通过排放槽的泄漏量。 可以在凹槽中形成二次电极接地以控制排出槽中的电场。

    • An impact absorber using an energy-absorbing, fluid-impregnated material consisting of a porous interconnected network of solid material forming edges and faces of cells, preferably an open-cell reticulated or partially closed-cell foam, or formed from fibers or other cellular solids. The matrix is impregnated with a field responsive fluid such as a magneto- or electro-rheological fluid, or with a shear-rate responsive fluid such as a dilatant (shear-thickening) fluid. The material is placed under compression during impact, and may be housed within a cylinder and compressed by a piston. The stiffness of the composite material consisting of a matrix filled with a field responsive fluid can be controlled by varying the field intensity and spatial gradients of the applied field to vary the rheological properties of the fluid.
    • 一种使用能量吸收的流体浸渍材料的冲击吸收材料,其由形成细胞的边缘和面的细胞的多孔互连网络组成,优选开孔网状或部分闭孔泡沫,或由纤维或其它细胞固体形成 。 基质用诸如磁 - 或电 - 流变流体的场响应流体,或与诸如膨胀(剪切 - 增稠)流体的剪切速率响应流体一起浸渍。 该材料在冲击期间被置于压缩状态下,并且可以容纳在圆筒内并被活塞压缩。 可以通过改变所施加的场的场强和空间梯度来改变流体的流变特性来控制由填充有场响应流体的矩阵组成的复合材料的刚度。
