Abstract
A vibration isolation system comprises four tunable dual-axis hydraulic inertial isolators, an array of accelerometers, and a controller. The controller inputs signals from the accelerometers and outputs signals to tune the isolators to minimize the vibration transmitted from a vibrating body to an isolated body. The isolators are tuned by varying the dimensions of their tuning passages or by application of magnetohydrodynamic force to the liquid within the tuning passages.
