Anti-moment machine and moment resisting device thereof
This disclosure is directed to an anti-moment machine and a moment resisting device thereof, device. The anti-moment machine has a machine body and at least one pair of moment resisting device. The moment resisting devices are respectively arranged on two sides of the machine body oppositely. Each moment resisting device has a base, a bracket, an elastic arm and a damper. The elastic arm is respectively connected to one side of the base and a bottom of the bracket, and an obtuse angle is defined between the base and the bracket. The damper is connected between the base and the bracket. The machine body is applied preload moments and preload lateral forces from the moment resisting device respectively to balance the moment in the machine body and reduce vibrations of the machine body.
