Inerter capable of adjusting inertance coefficient
The invention discloses an inerter capable of adjusting an inertance coefficient. The inerter comprises an upper lifting lug, a flywheel chamber, a flywheel, a lead screw, a stroke chamber, a lead screw nut and a lower lifting lug. The upper lifting lug is connected with the upper end of the flywheel chamber. The flywheel is located inside the flywheel chamber. The upper end of the lead screw is connected with the lower end of the flywheel. The lower end of the lead screw stretches out of the flywheel chamber and extends to the stroke chamber. The lead screw nut is located inside the stroke chamber. The lead screw nut is in screw-thread fit with the lead screw. The lower lifting lug is connected with the lower end of the stroke chamber. The periphery of the flywheel is provided with a rotor coil capable of rotating along with the flywheel. The periphery of the flywheel chamber is provided with a stator coil electrically connected with a power source. Rotation of the flywheel is restrained or accelerated by controlling the magnitude and direction of current generated by the power source, and therefore the inertance coefficient is adjusted to meet the requirement for practical engineering application. The inerter is suitable for being applied on a bridge to achieve the purpose of vibration reduction.
