Mounting assemblies and systems including same

A mounting assembly dimensioned for operative securement between an associated supporting component and an associated supported component, said mounting assembly comprising:

• a first mounting element and a second mounting element displaceable in at least one direction relative to said first mounting element;
• at least one positive-stiffness biasing element operatively disposed between said first and second mounting elements and exhibiting a positive-stiffness spring rate;
• and,
• a negative-stiffness biasing element assembly operatively disposed between said first and second mounting elements and exhibiting a negative-stiffness spring rate, said negative-stiffness biasing element assembly including a connecting ring, a first negative-stiffness biasing element disposed between said connecting ring and one of said first and second mounting elements, and a second negative-stiffness biasing element disposed between said connecting ring and the other of said first and second mounting elements with at least one of said first and second negative-stiffness biasing elements operatively disposed in parallel with said at least one positive-stiffness biasing element such that said mounting assembly exhibits a natural frequency that is less than a natural frequency of a mounting assembly having said at least one positive-stiffness biasing element without said first and second negative-stiffness biasing elements.

A mounting assembly dimensioned for operative securement between an associated supporting component and an associated supported component, said mounting assembly comprising:

• a first mounting element and a second mounting element displaceable in at least one direction relative to said first mounting element;
• a restraining strap operatively connected between said first and second mounting elements;
• at least one positive-stiffness biasing element operatively disposed between said first and second mounting elements and exhibiting a positive-stiffness spring rate;
• and,
• at least one negative-stiffness biasing element operatively disposed between said first and second mounting elements and exhibiting a negative-stiffness spring rate, said at least one negative-stiffness biasing element operatively disposed in parallel with said at least one positive-stiffness biasing element such that a combined spring rate of said at least one positive-stiffness biasing element and said at least one negative-stiffness biasing element is less than said positive-stiffness spring rate of said at least one positive-stiffness biasing element alone.
