Description

A kind of movable electrode giant electro-rheological fluid damper that interlocks
Technical field
The present invention relates to the technical fields of damper, more particularly to one kind staggeredly movable electrode giant electro-rheological liquid damping Device.
Background technology
Electro rheological fluids are to be dispersed in the suspension liquid formed in the solvent of low-k by the little particle of high-k. This suspension liquid can make solid particle polarize and interact under DC Electric Field in the moment of Millisecond, be formed flat Row is in the chain or column structure of electric field, to make this structure shape of similar solid that liquid shows as having certain yield stress State, makes apparent viscosity increase several orders of magnitude, and this effect for making fluid change state is called electric rheological effect.
Electro-rheological fluid damper be it is a kind of being widely used general energy-eliminating shock-absorbing control device, can be used for machinery, building etc. necks Domain.Its control mechanism is by the way that the electric rheological effect in damper, the partial vibration energy of structure is consumed by damping material It dissipates, achievees the purpose that alleviate the outer impact carried, reduces structural vibration, protection structure safety.
Giant electro-rheological liquid is to be dispersed in the one kind formed in the base fluid of giant electro-rheological liquid by polarizable dielectric particles to hang Supernatant liquid, when applying electric field to it, viscosity, shear strength etc. can transient change, the sizes such as viscosity, intensity with electric field adjusting, It continuously interior on a large scale can adjust, can reach several orders of magnitude, high viscosity fluid or even solid can be exchanged by low viscosity fluid. After extra electric field removes, fluid state, this attribute wink between liquid and solid can be restored within the millisecond time Between it is controllable, reversible, can continuously change, can pass through electric field realize torque controlled delivery and mechanism online stepless, reversible control System, can substitute traditional electrode machinery conversion component, have extensively in the self adaptive control mechanism industrial circle of electromechanical integration General application prospect especially has in fields such as national defense construction, the vehicles, hydraulic test, machinery manufacturing industry, sensor technologies More wide application foundation and application demand is one of the critical material that the development of damping vibration attenuation field is badly in need of.
Done research work is taught according to Hong Kong University of Science and Thchnology Wen Weijia, the novel giant electro-rheological liquid developed at present exists The yield strength that 130kPa or more can be reached under the electric field strength of 5KV/mm, can meet requirement of engineering completely.But it is this The coefficient of viscosity of novel giant electro-rheological liquid is only 1/10, the only 0.1Pas that common current becomes liquid, and general electric current Become the coefficient of viscosity of liquid as 1Pas.Therefore, under similarity condition, common current becomes the viscous damping force that liquid provides and is far longer than newly The viscous damping forces that type giant electro-rheological liquid provides.
During military service, vibration or shock loading can seriously affect its safety and use for various buildings or mechanical structure Service life.Installation can be reduced its vibration or shock response, increase its safety with the damping device of passive energy dissipation on above structure The effective means of property and stability.Traditional passive control damper (such as hydraulic damper) is only capable of providing uncontrollable damping Power, vibration control effect are undesirable.The intelligent damper prepared using electric/magnetic rheological body, can be by electric/magnetic field intensity Adjusting come according to operating mode it is real-time continuous adjust damping force, the active and half to realize structural vibration or impact are actively controlled System, is better protected from the failure damage of structure.Relative to MR damper, become by the electric current of core material of giant current Damper has many advantages, such as that stability is high, simple in structure, damping force adjustable range is big, response is fast.
According to operation principle, electro-rheological fluid damper is divided into shear mode, flow pattern and composite mode.In Practical Project In, usually require that electro-rheological fluid damper can provide larger damping force, this makes the er damping using traditional structural design Body accumulates and quality is larger.In addition, the sliding between ER fluid and damper electrode plate constrains filling for electro rheological fluids performance Distribution is waved, and practical damping force is caused to be less than theoretical damping power.Therefore, it is badly in need of developing that a kind of small volume, damping force be larger, pole plate Place is without sliding, novel electrorheological damper simple in structure, to meet the needs of industrial development.
Theoretical and experiment shows:In Practical Project, we with greater need for one kind can at passive control (null field, in the whole field), The damper of better effects can also be actively played with active control field half, this requires this dampers either passive Control still all has convenient viscous damping force in half active/active control, and provides larger yield stress.
However, the research at present about the structure design of damper and application is fewer, progress lags behind giant electro-rheological The research of liquid material self character.Existing automotive dampers are mostly hydraulic damping, have the characteristics that damping is nonadjustable.Separately Outside, the giant electro-rheological fluid damper of only a few is mostly unipolar plate, and is in theoretical research stage, relative to staggeredly adjustable multipole For the complicated electric field of plate, adjustable extent is still very limited.
