The invention discloses a rotary device for actively controlling structural vibration. A fixed assembly in the device is fixedly mounted on a controlled structure, wherein a track assembly is mountedon the outer surface of the fixed assembly in a surrounding manner through a connecting piece; corresponding coils are wound around lugs uniformly distributed in the track assembly and are wrapped bya housing; the coils serving as stators are externally connected with a power supply; one end, far away from the fixed assembly, of the housing protrudes; a driving assembly is clamped to the track assembly; a driving block in the driving assembly is in contact with the outer surface of the track assembly through a rolling piece and slides on the surface of a track; a magnetic piece is fixedly mounted on the driving block; the magnetic piece serves as a rotor and moves under the driving of the coils; the structural vibration is controlled under the action of the reaction force of the resultantforce of the driving force generated by the magnetic force and the centripetal force generated when the driving assembly moves; and the specification of the fixed assembly is adjustable, the fixed assembly is suitable for different structures, and the mass, the number and the initial position of the driving assembly are adjustable.
Description
technical field [0001] The invention relates to the technical field of vibration control, in particular to a rotary device for actively controlling structural vibration. Background technique [0002] With the development of social economy, there are more and more high-rise buildings and long-span bridge construction projects. In actual construction, the high-strength and lightweight materials used make the structures of high-rise buildings and bridges softer, but in earthquake or strong wind Under the action of vibration, a certain degree of vibration will be generated. On the one hand, it will bring people a sense of discomfort. On the other hand, it will also pose a threat to the safety of high-rise buildings and bridges. Therefore, the research on vibration control of high-rise buildings and bridges is very important. . [0003] For high-rise buildings, tuned mass dampers (TMDs) are often used today to control vibrations. For example, the single-pendulum golden ball of ...
