Design and implementation of passive suspension systems and their components has been thoroughly studied. There are inherent limitations on the amount of isolation that can be provided by using a simple suspension system consisting of spring and damper components. Design of such suspension systems involves a trade-off of the response at resonance, the displacement from static and impulse loads, and the isolation at high frequency. A solution, referred to as a hydraulic mount, is a passive suspension component that can be used to either isolate vibration at a particular frequency or to greatly increase damping at a particular frequency. The former use of hydraulic mounts is most common in aerospace applications while the latter use is most common in industrial applications. All hydraulic mounts require many components and a special fluid with associated filling and leakage concerns. Hydraulic mounts have been thoroughly studied with non-linear modeling and optimization techniques. There has also been work to add sensors, actuators, and control electronics to hydraulic mounts to create semi-active devices. While this method has yielded successful results, the devices often introduce the need for a power source and add complexity to the suspension system. This paper presents a theory for a passive vibration isolation component for which the effective stiffness changes with the frequency of steady-state operation. The effective stiffness can be passively adjusted, or tuned, to be a minimum at a particular frequency, thereby reducing transmitted vibratory forces at or near that frequency. The new suspension component offers performance similar to a lowly-damped, long-inertia-track hydraulic mount but with fewer components and with no fluid. Prototypes of the new suspension component have been built and tested. The results demonstrate that the new suspension component isolates vibratory forces for a relatively wide frequency range.
