A nonlinear spring mechanism incorporating a bistable composite plate for vibration isolation [PDF]

, 2013
The High Static Low Dynamic Stiffness (HSLDS) concept is a design strategy for a nonlinear anti-vibration mount that seeks to increase isolation by lowering the natural frequency of the mount whilst maintaining the same static load bearing capacity.
