Abstract

The invention relates to an shooting stem dry friction damper electric control device, including a static friction plate (5), a armature (8), a seat (11) and an electromagnet (14), wherein the seat is sleeved on the shaft, the static friction plate (5) is sleeved on the seat, the electromagnet is sleeved on the static friction plate. An electromagnet stand (7) is fixed on the seat (11), providing the resistance for the axial motion of the static friction plate (5) and the clamping force between a movable friction plate (4) and the static friction plate (5); the gap when the static friction plate (5) and the movable friction plate (4) are not working is adjusted through a locating nut (10). The invention solves the contact and the separating problems between the static friction plate (5) and the movable friction plate (4), also controls the force of friction between the static friction plate and the movable friction plate by electromagnetic force to adjust the outer damp added on the rotator.

Description

(1) Technical field: [0001] The invention relates to the field of rotor vibration control, and relates to an electric control device for a spring-supported dry friction damper. (two) background technology: [0002] As a new type of damping mechanism, the spring-supported dry friction damper has a good damping effect. Using it as a passive control device for rotor vibration can significantly reduce the vibration amplitude when the rotor exceeds the critical speed. In the patent "A Method and Device for Suppressing Vibration of a Rotor System with Elastic Support" (ZL200410073346.0), the elastic-support dry friction damper, as a passively controlled damping mechanism, cannot perform optimal control according to the vibration state of the rotor and has a long-term Dry friction has the disadvantage of overheating the friction surface. Therefore, it is of great significance to improve the spring-supported dry friction damper into an electronically controlled active control damp...
