The invention relates to a tuned mass damper for fan structure out-of-plane vibration control. The tuned mass damper for fan structure out-of-plane vibration control comprises a spring damping systemand a pry body. The spring damping system is connected between the front part of a fan cabin and the pry body, and comprises a rigid connecting rod, a rigid connecting plate, a spiral spring and a viscous damper, one end of the rigid connecting rod is fixed to the front portion of the fan cabin, the other end of the rigid connecting rod is fixedly connected with one end of the spiral spring and one end of the viscous damper through the rigid connecting plate, the spiral spring and the other end of the viscous damper are connected with the pry body, and the passive tuned mass damper is formed.The whole pry body serves as a mass block of the passive tuned mass damper, and fan cabin internal equipment including a gear box, a brake disc and a generator is arranged in the pry body. 本发明涉及一种用于风机结构面外振动控制的调谐质量阻尼器，包括弹簧阻尼系统和
