Patent ID: 6923298

Claim:
A shock and vibration isolation system for mounting equipment to a base wall, the system comprising: a load plate configured for attachment of the equipment thereto; a base plate configured for attachment to the base wall; the base plate being substantially parallel to the load plate; a spring arrangement disposed intermediate the load plate and the base plate, the spring arrangement engaging the load plate and the base plate to bias the load plate and the base plate in a separated relationship; at least one semi-active damper operatively connected to the load plate and the base plate for providing a selectively variable reaction force to the load plate and the base plate responsive to a relative displacement of the load plate with respect to the base plate; and an adaptive damper controller operatively connected to the at least one semi-active damper for controlling the reaction force applied to the load plate and the base plate, the damper controller including an optimum damper force determination module programmed for calculating an optimum reaction force F Opt using the equation F Opt =G 1 X Rel +G 2 V Rel where X Rel is the relative displacement between the load plate and the base plate, V Rel is the velocity of the load plate relative to base plate, G 1 is a first gain value and G 2 is a second gain value, the optimum damper force determining module being further programmed for calculating the first and second gain values based on an optimizable cost function.
