Embodiment 1

[0018] Embodiment one, combining Figure 1-Figure 3 , which provides the structure of an embodiment of a magnetically suspended active mass magnetically driven vibration control device. It includes a mass block 2, a DC excitation coil 4 as the secondary pole of the linear motor is installed on the lower part of the mass block, a slide rail bed 1 is arranged under the mass block, and a long stator winding 3 as the initial pole of the linear motor is arranged in the slide rail bed , the slide rail bed is in the shape of a rectangular groove, anti-collision spring groups 5 are installed on the two end walls 7 of the slide rail bed, and suspension electromagnet groups 6 are installed on both sides of the mass block and the side walls of the slide rail bed. Using constant conduction magnetic suspension technology (EMS) or superconducting magnetic suspension technology (EDS), install electromagnets or permanent magnets on the two sides of the mass block and the opposite rails, relyi...

Embodiment 2

[0019] Embodiment two, combining Figure 4 , which provides the structure of another embodiment of a magnetically suspended active mass magnetically driven vibration control device. It differs from the previous embodiment in that: the slide rail bed 11 is in an arc shape, and the bottom of the mass block 2 is in an arc shape. The curved track can save space and is especially suitable for installation in buildings with limited space. Different from the straight track, the horizontal projection size of the track should be reduced as much as possible to obtain the advantage of taking up less space. For this reason, the mass block should reduce its center of gravity height as much as possible, the flatter the form, the better, and make it have as much contact length as possible with the track, and make the motor stator winding 3 and DC excitation coil 4 arc according to the curvature of the track shape, respectively mounted on the top of the arc track 11 and the lower part of th...

Embodiment 3

[0020] Embodiment three, combining Figure 5-7 , which provides the structure of a non-magnetic levitation active mass magnetic drive vibration control device. It differs from Embodiment 1 in that: mass block supporting balls 12 are arranged on the slide rail bed. This makes it possible to omit the suspension magnet set. The manufacturing cost is relatively low.

Description

[0001] (1) Fields [0002] The invention relates to a damping control device. Specifically, it is a shock absorbing control device for civil engineering structures. (two), background technology [0003] At present, in order to ensure the safety of civil engineering structures under dynamic effects such as earthquakes and hurricanes, and reduce losses caused by natural disasters, civil engineering structures have introduced vibration control technology to protect structures on the basis of traditional seismic design fortifications. It is to add mechanisms, supports or energy-dissipating damping devices to the original structure to absorb the energy input to the structure by dynamic actions such as earthquakes and hurricanes, thereby reducing the dynamic response of the structure itself and achieving the purpose of protecting the structure. Typical methods include various passive control methods represented by increasing stiffness and damping, active control techniques that dyn...
