Abstract
The relative motion and force between two interconnected elements can be controlled by a semi-active two-stage adjustable damper to maximize isolation between the elements, while minimizing the instances of the motion exceeding acceptable limits. An algorithm determines when to apply the high force state of the damper to provide excellent isolation from input vibration and shocks. The dampers and control algorithms are useful in primary vehicle suspension systems, cab mounts, seat mounts and engine mounts.
