摘要 |
<p>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 second fluid-filled chambers which are interconnected by a passageway. 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 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.</p> |
