Detailed Description
In order to make the technical solutions of the present application better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are intended to be illustrative only and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the accompanying drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples consistent with certain aspects of the present application, as detailed in the appended claims.
Before the technical solutions of the present application are introduced, the background of the present application will be described first.
The working modes of the magnetorheological fluid of the existing magnetorheological equipment are a shearing mode and a squeezing mode, and the two modes are introduced respectively as follows:
(1) Shear mode
As shown in fig. 1, in the shear mode, after the voltage is applied to the magnetorheological device, the direction of the magnetic field (direction 11 in fig. 1) formed by the magnetorheological device is perpendicular to the direction of the pole plate 110, the moving direction of the pole plate (direction 12 in fig. 1) and the moving direction of the magnetorheological fluid (direction 13 in fig. 1).
(2) Squeeze mode
As shown in fig. 2, in the squeeze mode, after the voltage is applied to the magnetorheological device, the direction of the magnetic field (direction 21 in fig. 2) formed by the magnetorheological device is perpendicular to the direction of the pole plate 210 and the movement direction of the magnetorheological fluid (direction 23 in fig. 1), but perpendicular to the movement direction of the pole plate (direction 22 in fig. 2).
In the two modes, the fluid flow needs to directly destroy the magnetic chain segment, so that huge damping force is generated, the viscous resistance of the magnetorheological device is increased, and much energy is lost.
In the prior art, when a voltage is applied to the magnetorheological device, a voltage is applied to the outside of the rotor.
As discussed in the above section, in order to solve the above problem, embodiments of the present application provide a method, an apparatus, an electronic device, a medium, and a program product for determining viscous resistance, where in a case that it is detected that a magnetorheological device is in a non-operating state, a voltage is applied to a concentric cylinder structure of the magnetorheological device, so that an operating mode of a magnetic fluid in the magnetorheological device can be changed, and a magnetic segment in a magnetic field is not damaged when the magnetic fluid flows, thereby reducing the viscous resistance of the magnetorheological device.
The method for determining the viscous resistance provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.
Fig. 3 is a schematic flowchart of a method for determining a viscous resistance according to an embodiment of the present disclosure, where an execution subject of the method for determining a viscous resistance may be a server. The above-described execution body does not constitute a limitation of the present application.
As shown in fig. 3, the viscous resistance determination method provided by the embodiment of the present application may include steps 310 to 320.
And 310, under the condition that the magnetorheological device is detected to be in the non-working state, applying voltage to the concentric cylinder structure of the magnetorheological device.
In some embodiments of the present application, the concentric cylinder structure may include a rotor of the magnetorheological device, and a sleeve encasing the rotor.
In some embodiments of the present application, two drag reduction modes of operation are proposed, specifically, a parallel magnetic field mode and a circular magnetic field mode, according to the derivative of the conventional mode of the magnetorheological fluid (fig. 1 and 2) in the prior art.
The following description specifically refers to these two operating modes:
(1) Parallel magnetic field type
In some embodiments of the present application, applying a voltage to a concentric cylinder structure of a magnetorheological device may specifically include:
and applying voltage (or current) to a spiral line fixed on the inner side of a cylinder sleeve of a concentric cylinder structure of the magnetorheological device, so that the direction of a magnetic field formed after the voltage (or the current) is applied is parallel to the pole plate of the magnetorheological device, the motion direction of the pole plate and the flow direction of the magnetorheological fluid.
In one example, referring to FIG. 4, a voltage may be applied to a helical wire secured inside a sleeve of a concentric cylindrical structure of a magnetorheological device. As shown in FIG. 5, a parallel magnetic field is formed, the direction of the magnetic field (direction 51 in FIG. 5) is parallel to the pole plate 510 of the magnetorheological device, the moving direction of the pole plate (direction 52 in FIG. 5) and the flowing direction of the magnetorheological fluid (direction 53 in FIG. 5).
In the embodiment of the application, the voltage is applied to the spiral line fixed on the inner side of the cylinder sleeve of the concentric cylinder structure of the magnetorheological device, so that the direction of a magnetic field formed after the voltage is applied is parallel to the movement direction of the polar plate and the polar plate of the magnetorheological device and the flow direction of the magnetorheological fluid, the magnetic chain segments cannot be damaged when the magnetorheological fluid moves, and meanwhile, the mutual repulsive force among the magnetic chain segments can also realize the effect similar to magnetic suspension, thereby reducing the viscous resistance.
(2) Annular magnetic field type
In some embodiments of the present application, applying a voltage to a concentric cylinder structure of a magnetorheological device may specifically include:
and applying voltage (or current) to a rotor of the concentric cylinder structure of the magnetorheological device, so that the direction of a magnetic field formed after the voltage (or the current) is applied is parallel to a polar plate of the magnetorheological device and is vertical to the motion direction of the polar plate and the flow direction of the magnetorheological fluid.
In one example, referring to FIG. 6, a voltage may also be applied to the rotor of the concentric cylinder configuration of the magnetorheological device, such that a toroidal magnetic field may be formed. As shown in fig. 7, the direction of the magnetic field (direction 71 in fig. 7) is parallel to the plate 710 of the magnetorheological device and perpendicular to the direction of movement of the plate (direction 72 in fig. 7) and the direction of flow of the magnetorheological fluid (direction 73 in fig. 7). In the embodiment of the application, the rotor of the concentric cylinder structure of the magnetorheological device is applied with voltage, so that the direction of a magnetic field formed after the voltage is applied is parallel to the polar plate of the magnetorheological device and is perpendicular to the movement direction of the polar plate and the flow direction of the magnetorheological fluid, the magnetic chain segments cannot be damaged when the magnetorheological fluid moves, and the mutual repulsive force among the magnetic chain segments can realize the effect similar to magnetic suspension, thereby reducing the viscous resistance.
It should be noted that the above-mentioned two magnetic field generating devices of fig. 4 (the magnetic field generating device formed by applying voltage to the helical line fixed inside the sleeve of the concentric cylindrical structure of the magnetorheological device) and fig. 6 (the magnetic field generating device formed by applying voltage to the concentric cylindrical structure of the magnetorheological device) are improvements of the conventional magnetic field generating device (the magnetic field generating device formed by applying voltage to the outside of the rotor forming the two operation modes of fig. 1 and fig. 2), and the two magnetic field generating devices of fig. 4 and fig. 6 are not improvements of the magnetic field generating device of fig. 1 and fig. 2, and are independent from the two magnetic field generating devices of fig. 1 and fig. 2.
In the embodiment of the application, the drag reduction magnetic circuit (namely, two magnetic circuits shown in fig. 4 and fig. 6) is additionally arranged on the original magnetorheological brake or clutch, so that the viscous loss of the magnetorheological brake or clutch in a non-operating state is reduced, the energy consumption of the whole vehicle is reduced, and the dynamic property of the whole vehicle is improved.
And step 320, determining the viscous resistance of the magnetorheological device based on the voltage.
In some embodiments of the present application, in order to improve the determination accuracy of the viscous resistance, step 320 may specifically include:
controlling the movement of the magnetorheological fluid in the magnetorheological device based on the magnetic field formed after the voltage is applied;
acquiring the motion parameters of the magnetorheological fluid;
based on the motion parameters, a viscous resistance of the magnetorheological device is determined.
The motion parameter may be a parameter of the magnetorheological fluid during motion, and specifically may be a flow direction, a flow speed, and the like of the magnetorheological fluid.
In some embodiments of the present application, the motion of the magnetorheological fluid in the magnetorheological device may be controlled according to the magnetic field formed after the voltage is applied, then the motion parameters of the magnetorheological fluid may be obtained, and the viscous resistance of the magnetorheological device may be determined based on the motion parameters. How to determine the viscous resistance of the magnetorheological device based on the motion parameters belongs to the prior art, and is not described herein again.
In the embodiment of the application, the movement of the magnetorheological fluid in the magnetorheological device is controlled according to the magnetic field formed after the voltage is applied, then the movement parameters of the magnetorheological fluid are obtained, and the viscous resistance of the magnetorheological device is determined based on the movement parameters, so that the viscous resistance of the magnetorheological device can be accurately determined, and the determination accuracy of the viscous resistance is improved.
In some embodiments of the present application, in order to quantify the drag reduction effect of the two new magnetic fields (parallel magnetic field type and annular magnetic field type), the two new magnetic fields can be implemented by using a rheometer, and the variation trend of the torque with the current flowing through the magnetic field generator can be measured respectively. Because the steady-state test of the annular magnetic field needs to conduct electricity between moving parts, the method is characterized by using a dynamic test, and a group of control groups are made in the vertical magnetic field to explain the effectiveness of the method result.
Details of the experiment: the diameter of the rotor is 32mm; the diameter of the outer sleeve is 74mm; steady state test rotation 450rpm; the amplitude of the dynamic test is 10 degrees, and the angular frequency is 100rad/s.
Vertical magnetic field (vertical mode): a thin flexible copper wire wound in 38 turns;
toroidal magnetic field (parallel mode): a hard copper straight wire is placed inside the hollow rotor.
Through the above experiment, the following results were also obtained:
as shown in fig. 8, the steady-state test result of the vertical magnetic field in fig. 8 clearly shows that the torque is stable and significantly reduced with the current. And at 2.5A, about 17.5% drag reduction was achieved.
As shown in fig. 9, the vertical magnetic field dynamic test result of fig. 9 is very noisy, which is related to the defects of the dynamic test method itself and the insufficient flatness of the manufactured rotor. However, a clear drag reduction trend is still observed and a drag reduction effect of 19.4% maximum is obtained.
As shown in fig. 10, although the result of the toroidal magnetic field dynamic test of fig. 10 also has larger noise, a significant drag reduction trend can be seen, and a maximum 7.2% drag reduction effect is obtained. Failure to further reduce drag with increasing current is related to the fixation and centering of the copper wire.
In addition, fig. 8 to 10 each describe an example in which a current is applied to a concentric cylinder structure.
It should be noted that, in the method for determining the viscous resistance provided by the embodiment of the present application, the executing body may be the viscous resistance determining device, or a control module for executing the method for determining the viscous resistance in the viscous resistance determining device.
