Vertical liquid inertia vibration isolator

摘要：

A vibration isolator (10) for isolating the vibration of two bodies that are connected together is disclosed. The vibration isolator (10) comprises an inner cylinder (16) and a pair of outer housings (12, 14) concentrically bonded together with elastomer structures (18, 20) to form two chambers (22, 26) that are joined by a tuning port (24). The elastomer structures (18, 20) may serve both as the seals for the chambers (22, 26) and the compliant spring members in the isolator (10). The isolator (10) connects to a vibrating body by a spherical bearing (28). The chambers (22, 26) and tuning port (24) are filled with an inviscid fluid (34) and pressurized to prevent cavitation. In certain embodiments, pressure within the isolator (10) is maintained by a volume compensating device (30) connected to the chambers (22, 26) via a small diameter orifice (36).

公开了一种用于隔离连接在一起的两个体的振动的隔振器（10）。隔振器（10）包括内筒（16）和与弹性体结构（18,20）同心地结合在一起的一对外壳体（12,14），以形成两个腔室（22,26），其通过调谐港（24）。弹性体结构（18,20）可以用作腔室（22,26）的密封件和隔离器（10）中的顺应弹簧构件。隔离器（10）通过球面轴承（28）连接到振动体。腔室（22,26）和调音口（24）填充有不粘液体（34）并被加压以防止空化。在某些实施例中，隔离器（10）内的压力由经由小直径孔（36）连接到腔室（22,26）的体积补偿装置（30）维持。
