Beschreibung
Zusammenfassung:	The invention belongs to the technical field of engineering structure vibration control, and particularly relates to a magnetic negative stiffness damper stay cable vibration reduction device and a design method. The device comprises a supporting frame, a magnetic negative stiffness mechanism, a rotary eddy current damping mechanism and a transmission mechanism. The design method comprises the steps that the vibration frequency of a stay cable is determined; the mounting position of the stay cable vibration reduction device of the magnetic negative stiffness damper is determined; a stiffness parameter assembly of the stay cable vibration reduction device of the magnetic negative stiffness damper is designed; and a damping parameter assembly of the stay cable vibration reduction device of the magnetic negative stiffness damper is designed. The rotating speed of a rotary eddy current damping element is increased through a ball screw, and the energy consumption efficiency of the magnetic negative stiffness dampe
