    • A fluid filled type vibration damping device having: a first and a second mounting member linked by a rubber elastic body; a pressure-receiving chamber partially defined by the rubber elastic body with a non-compressible fluid sealed therein; an equilibrium chamber partially defined by a flexible film with the non-compressible fluid sealed therein; a first orifice passage connecting between the pressure-receiving and equilibrium chambers; and a rigid septum member partitioning the pressure-receiving chamber into a first pressure-receiving section partially defined by the main rubber elastic body and a second pressure-receiving section partially defined by a displaceable fluid pressure adjustment member. The two pressure-receiving sections communicate together via through-holes formed through the septum member, which constitute a second orifice passage tuned higher than the first orifice passage.
    • 一种流体填充式减振装置,具有:由橡胶弹性体连结的第一和第二安装构件; 由橡胶弹性体部分限定的受压室,其中密封有不可压缩流体; 由柔性膜部分地限定的平衡室,其中密封有不可压缩流体; 连接在受压室和平衡室之间的第一孔口通道; 以及将所述受压室分隔成由所述主橡胶弹性体部分地限定的第一受压部和由可移动的流体压力调节构件部分地限定的第二受压部的刚性隔膜构件。 两个压力接收部分通过隔膜构件形成的通孔连通在一起,构成通过调节高于第一孔通道的第二孔口通道。

    • A vibration controller includes a map controller, an adaptive controller, a set-up frequency judge/switcher, and an actuator. The map controller includes a data map storage for storing data on control signals determined in advance for a vibration insulator, and a signal generator for selecting one of the data, depending on a frequency of a cyclically pulsating signal emitted from a vibration generating source of a vehicle, from the data map storage and generating a control signal. The adaptive controller generates the control signal with respect to the cyclically pulsating signal using an adaptive control method. The set-up frequency judge/switcher switches from the map controller to the adaptive controller or vice versa based on the frequency of the cyclically pulsating signal. The actuator actuates an actuator of the vibration insulator based on the control signal generated by the map controller or the adaptive controller, whereby inhibiting the vehicle from vibrating.
    • 振动控制器包括地图控制器,自适应控制器,建立频率判断器/切换器和致动器。 地图控制器包括用于存储关于预先为振动绝缘体确定的控制信号的数据的数据图存储器,以及用于根据从振动发生源发出的循环脉动信号的频率来选择数据中的一个的信号发生器 车辆,从数据图存储并产生控制信号。 自适应控制器使用自适应控制方法产生相对于循环脉动信号的控制信号。 基于循环脉动信号的频率,设置频率判断/切换器从地图控制器切换到自适应控制器,反之亦然。 执行器基于由地图控制器或自适应控制器产生的控制信号来致动振动绝缘体的致动器,从而阻止车辆振动。
