摘要： Various embodiments provide a bush for isolating vibrations, the bush comprising: a first anchor part defining a longitudinal axis; a second anchor part disposed coaxially with respect to the first anchor part; a first resilient body operably engaged with the first anchor part; a second resilient body operably engaged with the second anchor part; and an inertial mass element disposed between the first anchor part and the second anchor part. The inertial mass element is independently connected to the first resilient body and the second resilient body. Also, the first resilient body, second resilient body and inertial mass element are arranged to isolate vibrations between the first anchor part and the second anchor part within a predetermined operational frequency range. Further, the inertial mass element is arranged to isolate the first anchor part and second anchor part from dynamic stiffness increases associated with eigenmodes of the first resilient body and the second resilient body in the predetermined operational frequency range.

摘要： A hydraulically damped mounting device (10) having a flow limiting element (42), such as a resilient diaphragm, in a switchable auxiliary passageway (36) that is in fluid communication with its working chamber (22). The switchable auxiliary passageway corresponds to an additional fluid mass that can be switched into and out of communication with the working chamber to control the vibration characteristics of the device.
