ABSTRACT:
There is provided an apparatus (10) for isolating an operating device against multi-dimensional disturbances which includes a series of spring assemblies (12) that are affixed between a support platform (14) and an operating device (16). The series of spring assemblies are affixed to a support platform (14) and mounted in three paired units to provide global isolation of the operating device against forces that act in five directions. Each spring assembly is equipped with a first and second set of spring elements (20) and (22) which absorb disturbance forces acting in an axial direction. The spring element (22) is a damping unit (30) which dampens the lateral vibrational forces caused by dynamic imbalance of the vibration-generating source. Included with each spring assembly is a load diverter (50) which serves to insulate the operating device against the sudden high vibrational forces that might be incurred during the launch of a satellite during the first minutes of the launch. The apparatus is described in connection with exploratory telescopes in space but provide advantages for insulating any operating device against multi-dimensional vibrational forces.
