Horizontal vibration isolation system with multi-tensioning wires having quasi-zero adjustable stiffness in three axes

An isolation system, configured to isolate a translational vibration in directions of an X-axis and a Y-axis and a torsional vibration around a Z-axis by being positioned between a ground and a load, wherein in order to provide a vibration isolation even if a weight of the carried load changes, the isolation system comprises;

• a base platform allowed to be associated with the ground,
• at least one load bearing platform allowed to be associated with the load,
• a plurality of beams or a beam group provided with equal distances between central axes of the plurality of beams and equal angles with respect to a center of the isolation system, between the base platform and the load bearing platform,
• a plurality of tensioning wires positioned adjacent to each of the plurality of beams or the beam group, providing that there is at least one for the plurality of beams or the beam group, in order to bring the base platform and the load bearing platform more adjacent together, to provide that the plurality of beams are compressed at least partially under force and accordingly, translational and torsional natural frequencies of the isolation system are changed.
