Shock, vibration and acoustic isolation system
First Claim
1. 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; and
a damping arrangement disposed intermediate the load plate and the base plate, the damping arrangement being adapted 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.

Abstract
A shock and vibration isolation system for mounting equipment to a base wall uses a semi-active damper in parallel with a spring arrangement to provide optimum isolation with respect to both shock and vibration. The system comprises a load plate configured for attachment of the equipment thereto and a base plate configured for attachment to the base wall. The base plate is substantially parallel to the load plate with a spring arrangement disposed intermediate the load plate and the base plate. The spring arrangement engages the load plate and the base plate to bias the load plate and the base plate in a separated relationship. The system also comprises a damping arrangement disposed intermediate the load plate and the base plate. The damping arrangement is adapted 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.
