FLUID-AND-ELASTOMER DEVICE

摘要

A damping device which provides superior damping stiffness K" has linear damping characteristics as a function of amplitude and for which the temperature sensitivities of stiffnesses K*, K", K' have been minimized. The device includes a first and second fluid-filled chambers (26 and 28) which are interconnected by a passageway (43). The length and diameter of the passageway, as well as the fluid viscosity, are chosen to give the optimum damping characteristics. Further, a plurality of spring loaded pressure relief valves (82) are integrated into the assembly to allow more flow area to open when a threshold pressure is encountered, thereby reducing the internal pressures and dynamic stiffness K* at cold temperatures.
