Description
Technical field
Method for filling more particularly to a kind of magnetorheological fluid for MR damper the present invention relates to a kind of fluid
Method for filling is mainly used for using when making MR damper control device, belongs to vibration damping control technology field.
Background technology
MR damper is a kind of novel intelligent control device, the semi- active control available for vibration.Its performance is not
Only influenced by the factors such as structure and magnetorheological fluid performance, the filling capacity of magnetorheological fluid be also influence its performance it is important because
Element.When being acted on by externally-applied magnetic field, magnetorheological fluid has the characteristics that high viscosity, lazy flow.When full resistance is perfused in magnetorheological fluid
During Buddhist nun's device internal cavities, the reciprocating motion of damper rod can make magnetorheological fluid pass through gap minimum between piston and cylinder barrel
So as to generate very big damping force.If magnetorheological fluid perfusion after the completion of, inside there are small air gap or bubble, magnetorheological fluids
Magnetic signature can be a greater impact, so as to influence the output of MR damper, response speed and temperature stability
Etc. characteristics.
The instillation process of existing damper magnetorheological fluid is mostly carried out by the way of injection, i.e., damper is had screw hole
End face is placed upward, using syringe, injects magnetic rheological liquid from the side of damper through screw hole, during injection not
Disconnected ground rotary-piston component, and the bubble generated in this course is punctured so that gas excludes in magnetic rheological liquid.When
When observing that magnetorheological fluid perfusion reaches damper screw hole upper surface position, stop injection, after being disposed vertically 1 hour, observation
Whether the liquid level at screw hole falls, if falling, continues to be injected into hole with syringe and fills up magnetorheological fluid, until liquid level weight
It is new be lifted to until screw hole upper surface flushes and liquid level no longer declines.It, also will be constantly during supplementing injecting fluid
Rotary-piston component, so that the gas being mixed into damper is discharged from screw hole.Using screw sealed damper screw hole, repeatedly
Tension and compression piston rod is multiple, then unscrews screw, and whether observation liquid level declines, if repeated aforementioned operation, until liquid level no longer declines,
Magnetorheological fluid perfusion terminates.But when using conventional syringe injection magnetorheological fluid, there are minute gas spaces inside damper
And bubble can be also generated in injection process, magnetorheological fluid is difficult to be fully populated with full damping device inner space, so that damper
Design and requirement is not achieved in performance after perfusion.In addition, because magnetorheological fluid has high viscosity, the characteristic of low flowing, take
Injection technique process is complex cumbersome, and required time is grown, and charging efficiency is low, is not suitable for the filling of batch damper magnetorheological fluid
Dress.Therefore the quality of the perfusion of damper magnetorheological fluid how is improved, the mode for improving perfusion is currently still to need further to be ground
The subject studied carefully.

It is to be in vacuum pressure as-0.02-- 0.01MPa that internal cavities of the perfusion system including MR damper, which are in vacuum state,
State, after the pumpdown time is the determining vacuum degree of arrival, voltage stabilizing until magnetorheological fluid from the inside of MR damper sky
Until chamber overflows, i.e., when vacuum pressure list index is directed toward-0.2-- 0.1 scale, voltage stabilizing until magnetorheological fluid from magnetorheological damping
The internal cavities of device overflow.
7. the magnetorheological fluid vacuum infusion method of MR damper as described in claim 1, which is characterized in that described to pass through
It is to be inserted into magnetorheological fluid that magnetorheological fluid is pressed under the action of atmospheric pressure in the internal cavities of MR damper by pipeline
The pipeline in magnetorheological fluid in container is equipped with control valve, includes the internal cavities of MR damper in entirely perfusion system
After vacuum state, the control valve being inserted into magnetorheological fluid in pipeline is opened so that the magnetorheological fluid in magnetorheological fluid container
Under the action of external pressure, the internal cavities of MR damper, magnetorheological fluid to be had are entered by the pipeline of insertion
After the internal cavities for filling MR damper, perfusion and pressure release will be stopped, MR damper, that is, complete is taken out after pressure release
Magnetorheological fluid bubble-free into MR damper is perfused.
