An isolation strut and strut support system for supporting a load and capable of operating in a first mode and a second mode comprising an air suspension spring connected to a load bearing shaft; a hydraulic damping element having a first chamber and a second chamber separated by a piston connected to the load bearing shaft. A hydraulic line has a valve therein, one end of the hydraulic line connected to the first chamber and the other end of the hydraulic line connected to the second chamber. A vibration detector is coupled to the valve for actuating the valve upon the occurrence of vibration of an abnormal quality; whereby, in a first mode of operation the load is rigidly attached to the ground via a load path through the hydraulic damping element and in a second mode the load is isolated by the air suspension spring and damped by the hydraulic damping element.
An isolation strut for supporting a load above a ground and capable of operating in a first mode and a second mode comprising:
A seismic isolation strut for rigidly supporting a platform during normal use and for damping motion in six degrees of freedom during an event of vibration exceeding a predetermined quality, comprising:
An isolation strut for supporting a load above a ground and capable of operating in a first mode and a second mode comprising:
