Between platform 1；Rotating bar 1, rotating bar 2 12 on two damping branch chains 1 rotate, and rotary shaft 15 rotates, and torsion spring 10 reverses
Stress deformation, the reaction force of rotary shaft 15 is transmitted to, connecting rod 13 rotates, and connecting rod 13 is connected with moving platform 1 so that moving platform
One 4 can rotate relative to silent flatform 1 around x-axis direction, because stress is different, the stress of spring 2 18 becomes 12 damping branch chains 23
Shape produces reaction force, because the reaction force of torsion spring 10 and spring 2 18 passes through rotating bar 1, rotating bar 2 12, connecting rod
13 and spring guide 17 be transmitted to moving platform 1, so as to can realize that moving platform 1 can rotate relative to silent flatform 1 around x-axis direction；
Partial spring 1 on two damping branch chains 1 is because of forced compression, the stretching of the stress of partial spring 1, moving platform 1 relative to
Silent flatform 1 has the free degree that moves along the x-axis, spring 1 because of reaction force caused by stress deformation by rotating bar 1, turn
Lever 2 12, connecting rod 13 are acted on moving platform 1, and 12 damping branch chains 23 are also because the difference of stress, spring 2 18
Power caused by stress deformation acts on moving platform 1 so that moving platform 1 can realize what is moved along x-axis relative to silent flatform 1
Vibration damping；Due to the effect of spring 1, torsion spring 10 and spring 2 18, two damping branch chains, one 2,12 damping branch chains 23 are by power
Collective effect is in moving platform 1 so that moving platform 1 has relative to silent flatform 1 to be rotated around x-axis direction, is moved along the x-axis direction
Move two frees degree so that moving platform 1 has relative to silent flatform 1 to be rotated around x-axis direction, vibration damping effect along the x-axis direction
Fruit.
The two degrees of freedom that moving platform 27 can bear to rotate around y-axis direction and move along the y-axis direction relative to moving platform 1
Vibration, moving platform 1 can bear that shaking for two frees degree is rotated and moved along the x-axis direction around x-axis direction relative to silent flatform 1
Four-degree-of-freedom dynamic, that final moving platform 27 can bear to rotate and move along x-axis, y-axis around x-axis, y-axis direction relative to silent flatform 1
Vibration；In summary when people is when on moving platform 27, the effectiveness in vibration suppression of four frees degree can be obtained.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent substitution or improvement made within refreshing and principle etc., should be included in the scope of the protection.
