ABSTRACT:
An active vibration isolation system which has three groups of airbag springs for supporting a load and isolating the load from vibration, together with a servo-valve system for admitting pressurized air to or exhausting pressurized air from each group of the airbag springs, and a damping system for damping movement of the load. The damping system comprises a plurality of pairs of shock absorbers which are mounted in parallel with and adjacent to the airbag springs. The shock absorbers are arranged so as to provide damping for each of the groups of airbag springs in three mutually-orthogonal directions.
