Abstract

The present invention relates to a method for preparing transmission interfaces of electric rheological liquid arrays. In the method, the arrays are designed according to the size of interface area by using the method that in a flat plate interface, the row distance of the array is from 9mm to 12mm; in a cylindrical interface, the row number N is an integer of d/11, and the row distance is phi d/N according to the size of a diameter d; the line distance of the array is 1 time to 1.4 times as long as the row distance; the array is a nonconductor straight strip, the thickness is from 0.3mm to 0.7mm, and the width is from 1.8 to 2.4mm; the nonconductor straight strip is adhered with a main interface to form the transmission interface of the electric rheological liquid array. The nonconductor array straight strip is arranged on the main interface, and is directly used as resistance which loses effects along the interface of electric rheological liquid, which is equivalent to increase the binding strength of the main interface and the electric rheological liquid; the nonconductor straight strip directly cuts the electric rheological liquid so that the shearing resistant strength of the electric rheological liquid is sufficiently exerted; the transmission interface for the nonconductor array reflects the true shearing resistant capability of the electric rheological liquid, but not the binding strength of the main interface and the electric rheological liquid.

Description

The method for preparing electrorheological fluid array transport interface

One, technical field

This relates to the method for preparing electrorheological fluid array transport interface, especially prepares the method for electrorheological fluid array transport interface.

Two, background technique

The method for preparing the electrorheological fluid transport interface of prior art is a gear-engaged type.Gear-engaged type mainly is to improve transmittability by the transport interface area that increases electrorheological fluid; Transport interface is transmitted the place of at first losing efficacy often; Moreover gear-engaged type electrorheological fluid transport interface increases component volume for increasing the transport interface area.

Three, summary of the invention

Goal of the invention of the present invention provides a kind of component volume that makes and does not increase, and directly becomes the method that prepare electrorheological fluid transport interface of electrorheological fluid along the resistance of interfacial failure with the nonconductor vertical bar.

The technological scheme that realizes goal of the invention is to solve like this: the preparation method is undertaken by following step:

A, according to the interfacial area size, array of designs, to dull and stereotyped interface, the array line space is 8～12 millimeters; To the tubular interface, by the size of diameter d, array line number N gets

Integer, line space is got π d/N;

The column pitch of b, array is 1～1.4 times of line space;

C, array are the nonconductor vertical bar, thick 0.3mm～0.7mm, and wide 1.8mm～2.4mm, small deformation can take place in length as required;

D, nonconductor vertical bar and female interface bonding constitute electrorheological fluid array transport interface.

The present invention compared with prior art, have following characteristics: on female interface, be provided with nonconductor array vertical bar, the nonconductor vertical bar directly becomes the resistance of electrorheological fluid along interfacial failure, be equivalent to increase the adhesive strength σ int of female interface and electrorheological fluid, promptly σ interface is the adhesive strength at electro rheological fluids and interface; The direct cutting current of nonconductor vertical bar becomes liquid, and the shearing strength σ ER of electrorheological fluid self is not fully exerted; What nonconductor array transport interface reflected is the real shearing resistance σ f ability of electrorheological fluid, but not the adhesive strength σ int between electrorheological fluid and female interface.

Five, embodiment

Accompanying drawing is two kinds of embodiments of the present invention

Below in conjunction with accompanying drawing content of the present invention is described further

Parameter interpretation among Fig. 1 is described as follows:

Ω ₁Ω ₂Be respectively initiatively rotating speed and the driven rotating speed of urceolus of inner core;

σ ER ... when referring to that electric field reaches certain value, ER fluid solidifies, the shear strength that its body has;

σ f ... the shearing force that the external loading torque is produced;

Mf ... the added load torque in urceolus surface;

Square secret note among Fig. 2 promptly is the nonconductor vertical bar of indication in 1, and main effect is the enhanced system transmission torque.

Below in conjunction with accompanying drawing content of the present invention is described further:

Shown in seeing figures.1.and.2, comprise smooth a urceolus and an inner core, liquid ER is housed between urceolus and the inner core and forms the interface of two different-diameters, this interface utilizes the characteristic of the anti-shearing stress of er material to carry out torque transmitting, promptly when driving shaft (inner core) with Ω ₁During the angular velocity rotation, can cause that driven shaft (urceolus) is with Ω ₂Angular velocity rotates, and can also drive load Mf and urceolus is outer, thereby play the effect of carry-over moment σ f.
