Abstract
The utility model relates to a current variable liquid and piezoelectric ceramic compounded self-adaptation damper. A piston cavity and a piezoelectric ceramic sheet are separated by a sealed baffle plate in a cylindrical barrel. A piston and a spring mechanism are used for acting on the piezoelectric ceramic to response the external vibration. The generated voltage output is connected with an electrode of a concentric circular ring column, which is fixed to a piston rod, causing the current variable liquid in the piston cavity to be solidified for increasing the damping force and reducing the vibration of the piston.
Description
The utility model relates to a kind of electrorheological fluid damping device, especially need not additional power source when work, can form degenerative electrorheological fluid and the compound self-adaptive damper of piezoelectric constant.
Because electrorheological fluid (writing a Chinese character in simplified form the ER fluid)
[1]Research, the ER fluid damper has appearred in recent years, this class damper is owing to the advantage of its Adjustable Damping joint causes people's very big interest.Duc-los
[2]Design the damped vibration absorption plant of two kinds of fundamental types: fixed electrode valve type and sliding plate type, in the fixed electrode type,, cause fluid pressure to raise because electric rheological effect is obstructed the fluid that flows through pole plate, produce damping force; In the sliding plate type,, electric rheological effect stop the relative movement of pole plate to produce damping force so that hydraulic coupling raises because producing shearing force between pole plate.Petek
[3]Design a kind of engine base made from electrorheological fluid, it has many parallel pipelines that electro rheological fluids is divided into two-part up and down.These pipelines have the valve of being done by electrorheological fluid, by the capacity of two-part electrorheological fluid about the control, thereby make base become hard, thereby play the purpose that reduces engine vibration.But in the damper that in the past goes out with the ER fluid design, the electric field that ER is solidified is to provide with high-voltage power in addition.Need also need complicated input and processing system to guarantee damper work simultaneously to the subsidiary power source special of damper with excitation ER fluid so on the one hand, it is very inconvenient that electro-rheological fluid damper should be used.
The purpose of this utility model is that a kind of electrorheological fluid and the compound self-adaptive damper of piezoelectric constant will be provided, and required additional power source and information processing when it can not only save the work of original current liquescent damper can form self-adaptive damping control simultaneously.
The purpose of this utility model is achieved in that electro-rheological fluid damper is linked together by spring and dividing plate and two piezoelectric ceramics that can produce high voltage output that output voltage is connected with the electrode group of damper with lead.When the external force effect moves downward piston, will pressure spring, exerting all one's strength reaches output voltage on the piezoelectric ceramic, reaches between the electrode by lead, and driving current becomes liquid-solidization.Applied force is big more, and the power that acts on the piezoelectric constant is also big more, and then Shu Chu voltage is high more, and strong more to the solidification of electrorheological fluid, promptly damping force is big more, thereby forms self-adaptive damper.
Owing to adopt such scheme, can when working, save by damper high-voltage power in addition and complicated control system, realize damping control easily and form self adaption regulating, and also simple in structure.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing according to the compound self-adaptive damper of the electrorheological fluid that the utility model proposes and piezoelectric constant.
Fig. 2 is the structure perspective view of self-adaptive damper of the present utility model.
Among Fig. 1: 1. loam cake, 2. go to the bottom, 3. piston, 4. dividing plate, 5. concentric column electrode group, 6. column piezoelectric ceramic, 7. cylindrical urceolus, 8. plectane, 9. spring, 10. piston rod, 11. leads of fixed electrode.
In embodiment Fig. 1, loam cake (1), go to the bottom (2) are installed on the cylindrical urceolus (7), and inside is divided into two-part up and down to self-adaptive damper by dividing plate (4), sealing between dividing plate (4) and the urceolus (7).On the top concentric column electrode group (5), the positive and negative electrode cross arrangement, have four electrodes, outermost negative electrode is fixed on the outer tube inner wall, does not move with piston rod (10), its excess-three plate is fixed on the piston rod (10) by two plectanes (8), plectane has aperture on (8), and piston (3) is installed on the piston rod (10), and piston has circular hole on (3), and certain interval being arranged with urceolus (7) inwall, piston (3) bottom links to each other with dividing plate (4) by spring (9).Fill current liquid between loam cake (1) and the dividing plate (4), constituting an electro-rheological fluid damper.In the bottom of self-adaptive damper, piezoelectric ceramic (6) vertically is installed in dividing plate (4) and goes to the bottom between (2), is connected on the cylinder electrode group (5) on top through lead (11) by the voltage of its output.
When extraneous vibration acts on the piston rod (10), make piston (3) when moving downward, it can pressure spring (9), through dividing plate (4) power is reached piezoelectric ceramic (6), thereby produce excitation and form high voltage, transfer on the cylinder electrode group (5) through lead (11), between electrode, form electric field, cause the electrorheological fluid curing of filling in it, stop flowing of piston intracavity liquid, the chamber internal resistance is increased, thereby piston motion is inhibited, and plays effectiveness in vibration suppression.This damper has saved required additional power source of original er damping device and information detecting processing system.It is bigger to add vibration force, and the power that is delivered on the piezoelectric ceramic (6) is bigger, and the output voltage of generation is higher, thereby the electric field that forms between electrode (5) is stronger, and the solidification of electrorheological fluid is also stronger, i.e. damping is big more, control to vibration is strong more, has formed self adaptive control.
