Abstract
The invention discloses a magnetorheological fluid sedimentation tester comprising an X-ray emission system, an X-ray imaging system, a control system, a base and a container containing magnetorheological fluid, wherein the container containing the magnetorheological fluid is a rectangular container with an opened upper part; and the rectangular container containing the magnetorheological fluid is placed on the base and between the X-ray emission system and the X-ray imaging system. By means of the magnetorheological fluid sedimentation tester disclosed by the invention, X-ray images of the magnetorheological fluid to be tested is obtained by utilizing different X-ray absorption capacities of substances with different densities, and the sedimentation conditions of the magnetorheological fluid to be tested are tested and evaluated through the analysis and the comparison of the X-ray images.
Description
Technical field
The invention belongs to a kind of testing tool, be specifically related to a kind of magnetic flow liquid sedimentation analyzer.
Background technology
Magnetic flow liquid is a kind of intellectual material, and it has different viscosity under different magnetic field environments, and therefore, magnetic flow liquid is widely used in all kinds of dampers as a kind of actuating medium; Magnetic flow liquid is a silicone oil, iron powder, the potpourri of adjuvant such as stabilizing agent and activating agent, because the proportion and the density of these materials have nothing in common with each other, so, when magnetic flow liquid under the condition that leaves standstill for a long time sedimentation can take place, make with the magnetic flow liquid is that the working performance of devices of actuating medium changes, and the sedimentation situation of magnetic flow liquid is to estimate an important indicator of magnetorheological fluid performance, and, the sedimentation of magnetic flow liquid is a progressive process that increases in time, therefore, by in the different time periods same magnetic flow liquid sample being carried out the test of sedimentation situation or the sedimentation situation of different magnetic flow liquid samples being compared, performance for evaluation and comparison magnetic flow liquid is very necessary, people have adopted the whole bag of tricks for this reason, and designed the testing tool that the sedimentation situation of magnetic flow liquid is tested and estimated, as: Chinese patent application number is " the magnetic flow liquid sedimentation hierarchical tester " of " 2004200638777 ", just can carry out to a certain degree test and evaluation to the sedimentation situation of magnetic flow liquid, but be positioned in the shifting magnetic field and test because this " magnetic flow liquid sedimentation hierarchical tester " is the container that will hold magnetic flow liquid, displacement to a certain degree takes place in the influence that will make ferromagnetic material in the magnetic flow liquid to be measured in the container be subjected to extraneous shifting magnetic field because of the existence of this shifting magnetic field, the displacement of ferromagnetic material can make other materials in the magnetic flow liquid to be measured be subjected to displacement again in the magnetic flow liquid to be measured, thereby the sedimentation situation of magnetic flow liquid to be measured is interfered, so, in using " magnetic flow liquid sedimentation hierarchical tester " test process to magnetic flow liquid, the ferromagnetic material and the distribution situation of other materials in magnetic flow liquid to be measured that will cause in the magnetic flow liquid to be measured along with moving of test magnetic field take place to a certain degree to change, make test result produce certain error, particularly in the repeatedly test of carrying out different time sections at a magnetic flow liquid sample, when estimating the sedimentation trend of this magnetic flow liquid sample, because of the shifting magnetic field can make this error become bigger to the repeatedly effect of magnetic flow liquid to be measured.
Summary of the invention
For overcoming existing magnetic flow liquid sedimentation hierarchical tester the sedimentation situation of magnetic flow liquid is tested the bigger deficiency of time error, the invention provides a kind of magnetic flow liquid sedimentation analyzer.
Technical scheme of the present invention is as follows:
A kind of magnetic flow liquid sedimentation analyzer, the container that it comprises X-ray emission coefficient, X-ray imaging system, control system, base and holds magnetic flow liquid, the container that holds magnetic flow liquid is the rectangular vessel of upper opening, the rectangular vessel that holds magnetic flow liquid be placed on the base and be placed on the X-ray emission coefficient and the X-ray imaging system between, and X-ray emission coefficient and X-ray imaging system are to link by control system.
Function of the present invention is achieved in that the rectangular vessel of magnetic flow liquid to be measured being put into upper opening, this container is placed between X-ray emission coefficient and the X-ray imaging system then, under the control of control system, open the X-ray emission coefficient, regulate the intensity and the hardness of the X-ray of its output, make X-ray pass the magnetic flow liquid to be measured in the rectangular vessel and project on the X-ray imaging system, density difference because of various materials in the magnetic flow liquid to be measured, so the ability of their absorption X-rays is just different, materials different in the magnetic flow liquid to be measured like this will produce different image gray in the X-ray imaging system, the image recording that records is got off and can estimate the sedimentation situation of magnetic flow liquid to be measured.Compared with prior art, the present invention does not have under the situation of not disturbing all substances in the magnetic flow liquid to be measured to distribute fully it is tested, and therefore, the present invention is higher to the accuracy of the test of magnetic flow liquid sedimentation situation and evaluation.

Embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Referring to Fig. 1, magnetic flow liquid sedimentation analyzer is made of X-ray emission coefficient 1, X-ray imaging system 2, control system 6, base 5 and the container 3 that holds magnetic flow liquid, and the container 3 that holds magnetic flow liquid is the rectangular vessel of upper opening; X-ray emission coefficient 1, base 5, X-ray imaging system 2 are positioned over respectively on the platform 9, the container 3 that holds magnetic flow liquid be placed on the base 5 and be placed on X-ray emission coefficient 1 and X-ray imaging system 2 between, container 3 and wherein the to be measured magnetic flow liquid 4 of the X-ray 10 that X-ray emission coefficient 1 is sent by holding magnetic flow liquid arrives X-ray imaging systems 2, and control system 6 is by the control that links of control line 7 and the 8 pairs of X-ray emission coefficients 1 and X-ray imaging system 2.
Method of testing is as follows: the container 3 that magnetic flow liquid 4 to be measured will be housed places on the base 5, open X-ray emission coefficient 1 and regulate intensity and the hardness that X-ray emission coefficient 1 is sent X-ray 10 by control system 6, when X-ray 10 by magnetic flow liquid 4 to be measured the time, make the different material in the magnetic flow liquid 4 to be measured in X-ray imaging system 2, present different image gray, after control system 6 shows the image that obtains and writes down, can test and estimate the sedimentation situation of magnetic flow liquid 4 to be measured.
