The servo-control system is by single chip microcomputer circuit board, acceleration transducer, liquid level sensor, water pump I and water pump II Composition.
The acceleration transducer is positioned over the top of main structure, and liquid level sensor is positioned in damper water tank.
The water pump I is positioned in damper water tank, for reducing the liquid level of tuning liquid;Water pump II is positioned over confession In regulating tank, for increasing the liquid level of tuning liquid;
, can be once after the single chip microcomputer circuit board receives and handles the signal of the acceleration transducer and liquid level sensor Property it is accurate calculate needed for regulation liquid level, and control the water pump I or water pump II disposably to complete the tuning liquid Liquid level is adjusted;
In the utility model, the half active Tuned Liquid is installed on the top of main structure.
In the utility model, the tuning liquid and confession regulation liquid can be water, silicone oil etc..
In the utility model, for the main structure occurred level to during vibration, tuning liquid produces damping with damping screen friction, Consumed energy.
In the utility model, the damping screen material can be copper, iron etc., quantity can depending on Practical Project can be 1~ 5.
Compared with prior art, the utility model has following advantageous effects:
Half active Tuned Liquid of the present utility model, servo-control system can be passed through by tuning the liquid level of liquid Accurate adjustment is carried out, and need not be adjusted in real time, is only carried out in the selected period, required delivery is small, being capable of accurate adjustment tune Humorous liquid condenser frequency is identical with main structure frequency;And the wind resistance of structure and the analysis design of antidetonation can be simplified, using tuning Liquid provides damping force with damping screen friction, and the energy is provided without the external world.With good endurance, effectiveness in vibration suppression is good, installation is simple The advantages that single and simple operation.
