1. float the rigidity vibration isolators such as the self adaption of damping three-dimensional decoupling zero based on magnetic, it is characterized in that:

  • comprise vibration isolation shell (1), three-dimensional suspension block (2), connection vibration-isolating platform (32) and the platform straight-bar (31) of described three-dimensional suspension block (2), the magnetic be installed between described vibration isolation shell (1) and three-dimensional suspension block (2) and float damped system;

    Described magnetic floats damped system, comprises stream and becomes liquid cylinder (42), is installed in described stream and becomes roller (41) on liquid cylinder (42) outside, be installed in described stream and become the inner and piston (44) that can be free to slide of liquid cylinder (42), be installed in the stream that described stream becomes liquid cylinder (42) open end and become fluid cylinder lid (43), be connected and can become fluid cylinder lid (43) free-moving piston rod (47) relative to described stream with described piston (44);

    Described stream becomes liquid cylinder (42) inside and is full of magnetic flow liquid, and described stream is become liquid cylinder (42) and is divided into two-part by described piston (44);

    stream becomes liquid first Room (45) and stream becomes liquid second Room (46);

    Described piston (44) offers multiple seepage flow hole (441), magnetic flow liquid flows between stream change liquid first Room (45) and stream change liquid second Room (46) back and forth by seepage flow hole (441);

    In the X, Y, Z direction, two, two, one described magnetic suspension damped system is respectively equiped with between described vibration isolation shell (1) and three-dimensional suspension block (2);

    The bottom that described stream becomes liquid cylinder (42) becomes fluid cylinder lid (43) be all equiped with hot-wire coil with described stream, for generation of magnetic field, and the state of control magnetic flow liquid;

    Described stream become liquid cylinder (42) by described roller (41) can on the corresponding internal surface of described vibration isolation shell (1) Free-rolling;

    On X, Y, Z tri-directions, it is separate that magnetic floats damped system, i.e. three-way rigidity decoupling zero.
