Embodiment Construction

[0011] The working block diagram of the torsional vibration active control system including the loading actuator is attached image 3 As shown, the torsional vibration signal of the rotor shaft system is detected by the sensor 10 and transmitted to the controller 11 through the conditioning circuit. The controller 11 sends out a control signal to control the action of the actuator according to the corresponding control objective function and control law, and the actuator loads the control force on the torsional vibration. On the shaft 1, the torsional vibration of the shaft 1 is reduced and suppressed.

[0012] Refer to attached figure 1 , the torsional vibration shaft 1 has two states during operation.

[0013] I. The torsional vibration shaft 1 is running normally, no torsional vibration occurs or the vibration is very slight, and no active control force needs to be applied. At this time, the DC servo motor 9 is stopped, the brake 8 is in braking, the clutch 7 is in a disen...

Abstract

The performer is composed of the master and slave drive gear, master and slave friction wheel, transmitting shaft, electro-magnetic clutch, brake and bidirectional direct current serving motor. The torsioning vibration shaft is the main shaft, a transmitting shaft is set parallelly. The transmitting shaft rotate synchronized through the friction wheel, the transmitting shaft under the effect of the serving motor, electro-magnetic brake and electro-magnetic clutch, the collision action of the slave and master gears engender the instantaneous torque which is loaded on to the vibrating shaft to eliminate the vibration.

Description

technical field [0001] The invention belongs to the field of mechanical vibration, and in particular relates to a vibration active damping technology for transmission of impact torque through a gear-based transmission structure. Background technique [0002] At present, in the field of mechanical dynamics and its control, active vibration control technology has become a research hotspot. Active vibration control includes three key points: the control objective function, the controller to realize the objective function, and the actuator to load the control force. There are different loading control force actuators for different vibration forms: ①Controllable extrusion oil film bearing——by balancing the eccentricity of the rotor mass, changing the oil film characteristics, and controlling bending vibration; ②Active balance calibration variable mass device——by adjusting the mass of the shafting system Eccentric, a device that realizes the active...
