Abstract
The utility model discloses a wind control stay cable magnetorheological damping device, which comprises a stay cable, a magnetorheological damper, a support and a damper adjuster. An output end of the damper adjuster is connected with a wiring end of an electromagnetic wiring end of the magnetorheological damper, an input end of the damper adjuster is connected with an output end of a wind driven generator, and the wind driven generator is mounted on the support. The wind driven generator not only can be utilized as a sensor controlled by the magnetorheological damper, but also can be utilized as a driving power source of the magnetorheological damping device, thereby saving cost and energy and increasing reliability. In addition, the wind control stay cable magnetorheological damping device is small in volume, attractive in molding and small in quantity of cables, does not mess bridge floors, and can realize continuous adjustment of damping force of the magnetorheological damping device without complex control methods or kinetic models, so that stay cables have excellent vibration absorbing effect.
Description
Technical field the present invention relates to a kind of Inclined Cable Vibration control device, and particularly a kind of wind-driven generator that utilizes is as suspension cable sensor, controller and driving power, and by the suspension cable magnetorheological damping device of wind control.
Background technology is in order to reduce, suppress the bridge stay cable vibration, and many cable stayed bridges are installed vibration absorber at its suspension cable bottom end vicinity, as passive hydraulic damper, high-damping rubber circle, MR damper etc.Passive hydraulic damper and high-damping rubber circle do not need sensor, controller and power supply, belong to a kind of passive type damper.Passive type damper damping force size can not be regulated with magnitude of vibrations, and affected by environment very big, is difficult to the effectiveness in vibration suppression that reaches desirable.MR damper generally needs extra sensor, controller and driving power, so belong to a kind of half active damper.Add different exciting currents on the MR damper magnet exciting coil, MR damper just can produce the damping force of different sizes, thereby makes every drag-line be in work under the optimal damper state, reaches the purpose that suppresses inhaul cable vibration.
The known MR damper that is used for the suspension cable vibration damping all need be installed vibration displacement or acceleration transducer, controller and power supply on drag-line at present.This kind method cost an arm and a leg, influence bridge cable attractive in appearance, need a large amount of cables; And control is complicated, need set up the kinetic model of drag-line damping system, is difficult to select suitable control method.Also have some to adopt according to weather forecast and manually preestablish MR damper operating current size, this kind method can not be regulated the damping force size in real time according to the inhaul cable vibration situation, and effectiveness in vibration suppression is reduced greatly.
The summary of the invention the purpose of this utility model is exactly at the deficiencies in the prior art, provide and utilize the magnetorheological damping apparatus of wind-driven generator as sensor, controller and driving power, regulate the MR damper damping force to satisfy in real time with wind-force, by the suspension cable magnetorheological damping device of wind control.
For achieving the above object, the utility model adopts following technical scheme:
A kind of suspension cable magnetorheological damping device by wind control, comprise suspension cable, MR damper, support, damper adjuster, the output of damper adjuster is connected with the electromagnetic coil terminals of MR damper, it is characterized in that: the input of described damper adjuster is connected with the output of wind-driven generator, and wind-driven generator is installed on the support.
Preferably, described wind-driven generator is a micro wind turbine generator.
Owing to adopted technique scheme, the connection of micro wind turbine generator output voltage enters into adjuster, and adjuster output is fit to the required drive current of MR damper in the MR damper magnet exciting coil.Damper one end is fixed on the drag-line, and the other end is fixed on the support.When suspension cable was carried by little wind, the voltage that micro wind turbine generator sends was lower, and is less by the drive current of exporting behind the adjuster, shakes thereby the less damping force of MR damper output suppresses less drag-line wind; When suspension cable suffered to carry than strong wind, the voltage that micro wind turbine generator sends is higher, and was bigger by the drive current of exporting behind the adjuster, shakes thereby the bigger damping force of MR damper output suppresses bigger drag-line wind; In the time of calm year, MR damper also can be used as the passive type hydraulic buffer, suppresses the inhaul cable vibration that load such as rainy and vehicular impact cause.In the time of calm year, MR damper can be used as the passive type hydraulic buffer, suppresses the inhaul cable vibration that load such as rainy and vehicular impact cause.
The beneficial effect of a kind of suspension cable magnetorheological damping device by wind control of the utility model is, utilize wind-driven generator both as the sensor of MR damper control, as the MR damper driving power, provide cost savings again, save the energy, improved reliability; Volume is small and exquisite, and is handsome in appearance, do not have a large amount of cables, and bridge floor is clean and tidy, need not complicated control method and kinetic model, just can realize that the MR damper damping force is adjustable continuously, makes drag-line obtain good effectiveness in vibration suppression.
