    • A liquid-filled vibration isolator has a first orifice channel providing communication between a pressure receiving chamber and a balancing chamber. One of the pressure receiving chamber and the balancing chamber is communicated via a second orifice channel with an intermediate liquid chamber. The second orifice channel has a shorter distance or a larger cross-sectional area than the first orifice channel. An elastic film member, such as a membrane, separates the intermediate liquid chamber and the other of the pressure receiving chamber and the balancing chamber from each other. A communicating hole of a predetermined size is formed in the elastic film member. An imaginary orifice channel combined from the two orifice channels provides a high damping effect on input vibration of relatively low frequency. As the vibration frequency increases, a gradual transition is made to the damping characteristic of the second orifice channel only.
    • 液体填充的隔振器具有提供压力接收室和平衡室之间的连通的第一孔口通道。 压力接收室和平衡室中的一个经由第二孔口通道与中间液体室连通。 第二孔口具有比第一孔口更短的距离或更大的横截面面积。 诸如膜的弹性膜构件将中间液体室和压力接收室和平衡室中的另一个彼此分离。 在弹性薄膜构件中形成预定尺寸的连通孔。 从两个孔口组合的假想孔口通道对相对低频率的输入振动提供高阻尼效应。 随着振动频率的增加,仅对第二孔口的阻尼特性进行逐渐转变。

    • In a liquid-filled anti-vibration mounting device suitable such as for an engine mount, an accommodation room containing a rubber movable plate is formed inside a partition member partitioning a liquid chamber into a pressure receiving chamber and a balancing chamber. The partition member includes a pair of division walls, one adjoining the pressure receiving chamber and the other adjoining the balancing chamber. Each division wall is formed with a plurality of communication holes. The communication holes are arranged to undulate at least a portion of the movable plate towards the peripheral edge thereof at specified circumferential intervals or greater by the action of the liquid pressure through the communication holes. The movable plate thus deformed, particularly its portion towards the peripheral edge, has a small area to come into contact with the division walls at a time, which effectively disperses and lessens a shock due to contact.
    • 在适用于发动机支架的充满液体的防振安装装置中,在将液体室分隔成压力接收室和平衡室的分隔部件内形成有容纳橡胶活动板的容纳室。 分隔构件包括一对分隔壁,一对分隔壁邻接压力接收室,另一个邻接平衡室。 每个分隔壁形成有多个连通孔。 连通孔布置成通过通过连通孔的液体压力的作用以特定的圆周间隔或更大的波长使可动板的至少一部分朝向其周边边缘波动。 这样变形的移动板,特别是其朝向周边边缘的部分,具有一小的面积,以便与间隔壁一次接触,这有效地分散并减轻了由于接触引起的冲击。

    • In an abnormal noise inspection method for an anti-vibration device for vehicle use, it is determined whether, during travel of a vehicle in which a supported member is supported to the vehicle body by an anti-vibration device, abnormal noise occurs or not in the passenger compartment owing to the anti-vibration device. The method includes: an input step of mounting to a shaker the anti-vibration device before it is assembled into the vehicle and then inputting vibrations in a predetermined pattern to a supported member-side mounting part of the anti-vibration device; a measurement step of measuring, during the inputting of vibrations, a transmission force output from a vehicle body-side mounting part of the anti-vibration device; an analysis step of frequency analyzing time-series data on the measured transmission force to obtain a power spectrum of the transmission force; and a determination step of estimating, based on the power spectrum of the transmission force and according to a predetermined evaluation criterion, whether a vehicle produces abnormal noise in the passenger compartment when it runs with the anti-vibration device mounted thereon.
