Description
Technical field
The invention belongs to Precision Piezoelectric actuation techniques fields, and in particular to a kind of permanent magnet controlled standard magnetorheological fluid piezoelectricity straight line
Driver.
Background technique
In recent years, domestic and international large quantities of scientific research institutions and colleges and universities drive around Precision Piezoelectric has carried out a large amount of research work,
The research achievement accumulated makes piezoelectric driving technology reach its maturity with practical experience, and Piezoelectric Driving product flourishes.From 20 generation
It has recorded since the Japanese scholars eighties take the lead in successfully researching and developing piezoelectric ultrasonic motor, all kinds of different driving mechanism, different ways of realization, no
Isostructural piezoelectric actuator is come out one after another.According to active principle, driving element, the difference of motion mode, piezoelectric actuator can
To be subdivided into multiple and different classifications.
According to drive mechanism and motion mode difference, Direct Action Type Precision Piezoelectric driver, Inchworm type piezoelectricity essence can be divided into
Close driver and inertia-type Precision Piezoelectric driver etc..Wherein, compared with the drivers such as traditional electromagnetic motor, directly
Dynamic formula piezoelectric actuator has simple and compact for structure, and feeding is continuous, it can be achieved that the characteristics of high-torque exports, but defect is mainly concentrated
Hinge arrangement is needed to amplify stroke is smaller, sluggishness and creep non-linear effects of the displacement accuracy by piezoelectric stack are multidirectional soft
Property hinge mutually exist interference with influence etc..Inchworm type piezoelectric actuator has big stroke, large driving force and high-resolution
Key property.But itself limiting due to drive mechanism, the type driver is both needed to design clamp structure, this makes to drive
Device mechanical structure bulky complex leads to complete machine microminiaturization relatively difficult to achieve；Secondly, to be also required to multichannel clock signal defeated for circuit part
Out, to propose high requirement to circuit control system.
And inertia-type piezoelectric actuator therein, mainly by driving mass block to vibrate the inertia force generated by piezoelectric element
The drive force formed with friction fit, to guarantee preferable working performance, the quasi-driver to method of friction control with
More stringent requirements are proposed for frictional contact surface precision.The friction shape of the friction apparatus for adjusting force of piezoelectric inertia driver now
Formula is mainly solid-solid friction, and solid-solid friction is related with contact surface microstructure, surface abrasion situation, is a kind of
Complicated, uncertain energy loss form, therefore, solid-solid friction will affect driver overall performance.And magnetorheological fluid
It is a kind of Intelligent fluid, similar with Bingham fluid under magnetic fields, magnetic-particle forms magnetic linkage in magnetorheological fluid, and fluid is viscous
Degree can obviously increase, and there are yield stresses, and before stress reaches yield stress, magnetorheological fluid is similar to solid, will not destroy
Magnetic linkage and generate flowing, magnetic linkage will be destroyed and generate flowing after reaching yield stress, in magnetorheological fluid, yield stress energy
It is accurately controlled by the change in magnetic field.Solid-liquid/solid-class solid friction type brought by the introducing of magnetorheological fluid
It is a kind of very novel effective technological means, it keeps frictional force moderate and adjustable, wears small, and can improve the drive of inertia-type piezoelectricity
Dynamic device performance, expands application range.
