Close rotary inertia driving control system.
Background technique
Vibration is a kind of phenomenon common in life, and job facilities, structure are in use often due to external lotus
The effect of load generates vibration, and serious generation is waved, or even destroys.It is various caused by being vibrated by works in order to solve the problems, such as,
Vibration control technology comes into being.
In terms of structural vibration control technology is broadly divided into following four: active control, passive control, semi- active control and
Mixing control.For various engineering structures, properly safe vibration control system can effectively mitigate the dynamic response of structure,
Mitigate structural damage or fatigue damage.
The movement of structure is usually composed of translation and torsionoscillation.Research shows that due to translation tuning quality damping
Device (English name Tuned Mass Damper, TMD), active mass damper/active torque output device (English name Active
Mass Damper/Driver, AMD) cause control effect to weaken significantly even due to needing to provide centripetal force in torsionoscillation
Completely ineffective, to turning round, shimmy control is nearly unavailable.However there is the structure motion form pole for turning round shimmy kinetic characteristic

Body stance adjustment and solar energy sailboard reverse lagging motion caused by opening；High-speed railway locomotive, since small excitation causes
The torsion lagging motion of vehicle body etc..Therefore a kind of special control system is needed, allows to overcome (or getting rid of) weight automatically
Influence (centrifugal force effect) of the field of force to control system itself, or make the work/characteristics of motion and gravity of control system itself
Field decoupling, system self-vibration is not influenced by gravitation, to play the effective control action of control system.
Active control technology is quickly grown in recent years because it has the advantages that control effect is good, robustness is good.But
In the research and practice process of technology, it has been found that work is driven since active control device needs extra power, in engineering
When structure is by destroying, the supply of the energy will lead to the entirely ineffective of active control device by accidental amputation.
To sum up, Structural Vibration Control Systems have indispensable role, but existing Structural Vibration Control Systems have
Have a deficiency of following several respects: first, translation TMD control device can only control structure translational motion and to turning round shimmy control
In vain, although it is shimmy to can control revolution for translation AMD control device, but control efficiency is extremely low, is unable to satisfy requirement；The
Two, passive rotation inertia tuned damper is effective to shimmy motion control is turned round, but it needs to be answered for structure itself
Miscellaneous frequency modulation, lower to certain labyrinth control efficiencies, ineffective, it is low that there are robustness, and controllability is low, and the scope of application is small
The disadvantages of；Third, the control system scope of application is small, and control force output is limited, and control effect is limited, and control system using energy source
Rate not can guarantee, and be unable to satisfy the demand of economy；4th, actively although (rotation) control device can solve above-mentioned three aspect and ask
Topic, still, there are the entirely ineffective risks of unexpected energy cutting control system.
The utility model is exactly to generate in this context.
