Abstract
A mounting assembly () includes first and second mounting components () that are displaceable relative to one another. At least one positive-stiffness biasing element () exhibiting a positive-stiffness spring rate is operatively disposed between the first and second mounting components. At least one negative-stiffness biasing () element exhibiting a negative-stiffness spring rate is disposed between the first and second mounting components in parallel with the at least one positive-stiffness biasing element. A combined spring rate of the at least one positive-stiffness biasing element and the at least one negative-stiffness biasing element is less than the positive-stiffness spring rate of the at least one positive-stiffness biasing element alone. The mounting assembly can exhibit a natural frequency that is less than a natural frequency of a mounting assembly having the at least one positive-stiffness biasing element without the at least one negative-stiffness biasing element. Systems including such mounting assemblies are also included.
