Description

有场下磁流变液摩擦磨损特性检测装置 Detection device for friction and wear characteristics of magnetorheological fluid under a field

技术领域 technical field

本发明属于磁流变材料检测技术领域,具体涉及磁流变液摩擦磨损特性检测装置。 The invention belongs to the technical field of magnetorheological material detection, and in particular relates to a detection device for the friction and wear characteristics of magnetorheological fluid.

背景技术 Background technique

目前,具有优良磁流变性能的多相体系磁流变材料在工程机械中得到了广泛的应用,对于这种多相体系而言,由于产生磁效应的悬浮相多为硬质磁性颗粒,这些颗粒的摩擦磨损性能将严重影响磁流变器件的使用寿命。此外,磁流变材料在抛光技术领域已经得到较为成功的应用,在对工件进行抛光作业时,往往需要连续调节磁场大小对磁流变材料实施精确控制从而达到完美的处理效果,这对磁流变材料的摩擦磨损性能提出了更高的要求。因此,考察无磁场和磁场条件下磁性流体的摩擦磨损性能是非常必要的。从网上搜索、文献资料和调研结果看,目前有关磁流变液摩擦磨损性能的研究还较少,大多工作还停留在无磁场下的研究阶段。在1989年第二届国际电流变会议上,Lingard和Bullough首次报道了电流变液的摩擦学研究,告诫从事这一领域的研究者在设计磁流变液和电流变液时,不要忽略它们的润滑性能。P. L. Wong等【The effect of particle concentration in a magnetorheological suspension on the performance of a boundary lubricated contact,Proc. Instn Mech. Engrs Vol.218 Part J:J. Engineering Tribology,2004,218:251~263】采用环块试验考察了粒子浓度对磁流变液摩擦学性能的影响。Bullough等【Tribological performance of a magneto-rheological suspension,Wear,2001,247:33~40】采用环-块摩擦试验机,在固定的速度、载荷、PV值和摩擦时间等条件下,考察了磁流变液的摩擦系数随颗粒浓度的变化、粗糙度随时间的变化,磨斑直径大小和摩擦块失重,用电镜表征了环、块的表面变化情况。张平等【磁流变液体材料的稳定性和润滑性研究,功能材料,2005,36(8):1192~1195】用四球机法测量了羰基铁/矿物油体系磁流变液的润滑性能。Wang L.J.等【Tribological properties of Mn–Zn–Fe magnetic fluids under magnetic field,Tribology International,2009,40:792~797】通过增加或减少永磁体的个数控制磁感应强度,分析了磁场对锰-锌-铁纳米合金磁流体的摩擦磨损性能影响。宋世远等【油料模拟台架试验[M],北京: 中国石化出版社, 2001:151-169】 报道了摩擦磨损试验机的应用。4个钢球在试验油盒中以等边四面体排列、上球固定在夹头中并由主轴带动旋转,下面3个钢球用油盒固定在一起,通过弹簧式加载系统自下而上对钢球施加一定负荷。试验过程中4个钢球的接触点都浸没在试样中,运转一定的时间,计算机记录实验过程中的摩擦系数,通过显微镜测量油盒内1个或3个钢球的磨痕直径,评定试样的摩擦磨损性能。但上述文献报道的多相体系磁流变材料的摩擦磨损试验大多是在无磁场下完成的,只有一小部分的研究设计了永磁体来施加磁场,而这些装置得到的磁场强度较小,并且磁场强度的变化不可连续调节。这些文献报道的磁流变材料摩擦磨损性能检测试验存在以下不足: At present, multi-phase system magnetorheological materials with excellent magnetorheological properties have been widely used in construction machinery. For this multi-phase system, since the suspension phases that generate magnetic effects are mostly hard magnetic particles, these The friction and wear properties of particles will seriously affect the service life of magnetorheological devices. In addition, magnetorheological materials have been successfully applied in the field of polishing technology. When polishing workpieces, it is often necessary to continuously adjust the magnitude of the magnetic field to implement precise control of magnetorheological materials to achieve perfect processing effects. The friction and wear properties of variable materials put forward higher requirements. Therefore, it is very necessary to investigate the friction and wear properties of magnetic fluid under the condition of no magnetic field and magnetic field. According to online search, literature and investigation results, there are still few studies on the friction and wear properties of magnetorheological fluids, and most of the work is still in the research stage without magnetic field. At the Second International Electrorheological Conference in 1989, Lingard and Bullough reported the tribological research of electrorheological fluids for the first time, and warned researchers in this field not to ignore their characteristics when designing magnetorheological fluids and electrorheological fluids. lubricating properties. P. L. Wong et al【The effect of particle concentration in a magnetorheological suspension on the performance of a boundary lubricated contact, Proc. Instn Mech. Engrs Vol.218 Part J:J. Engineering Tribology, 2004, 218: 251~263] The effect of particle concentration on the tribological properties of magnetorheological fluid was investigated by ring block test. Bullough et al [Tribological performance of a magneto-rheological suspension, Wear, 2001, 247: 33~40] Using a ring-block friction tester, under the conditions of fixed speed, load, PV value and friction time, the friction coefficient of magneto-rheological fluid was investigated. With the change of particle concentration, the change of roughness with time, the diameter of wear scar and the weight loss of friction block, the surface changes of ring and block were characterized by electron microscope. Zhang Ping [Study on Stability and Lubricity of Magnetorheological Fluid Materials, Functional Materials, 2005, 36(8): 1192~1195] measured the lubricity of carbonyl iron/mineral oil system magnetorheological fluid by four-ball machine method. Wang L.J. et al【Tribological properties of Mn–Zn–Fe magnetic fluids under magnetic field, Tribology International, 2009, 40: 792~797] The magnetic induction intensity was controlled by increasing or decreasing the number of permanent magnets, and the friction of the magnetic field on the manganese-zinc-iron nano-alloy ferrofluid was analyzed Abrasion performance effects. Song Shiyuan et al [Oil Simulated Bench Test [M], Beijing: Sinopec Press, 2001:151-169] reported the application of friction and wear testing machine. The 4 steel balls are arranged in an equilateral tetrahedron in the test oil box, the upper ball is fixed in the chuck and rotated by the main shaft, the lower 3 steel balls are fixed together with the oil box, and are loaded from bottom to top by a spring-type loading system A certain load is applied to the steel ball. During the test, the contact points of the 4 steel balls are all immersed in the sample, run for a certain period of time, the computer records the friction coefficient during the test, and the diameter of the wear scar of 1 or 3 steel balls in the oil box is measured by a microscope, and evaluated Friction and wear properties of the samples. However, most of the friction and wear tests of multi-phase system magnetorheological materials reported in the above literature are completed without a magnetic field, and only a small part of the research designs permanent magnets to apply a magnetic field, and the magnetic field intensity obtained by these devices is small, and The variation of the magnetic field strength is not continuously adjustable. The detection tests of the friction and wear properties of magnetorheological materials reported in these literatures have the following deficiencies:

一是实验结果不能全面反映磁流变材料的摩擦磨损性能。在磁场作用下,磁流变材料中的磁性颗粒被极化,重新排列、成纤,磁性流体的黏度及润滑条件将发生很大变化,此时磁性材料的摩擦性能与无磁场时有明显不同。因此,无磁场条件下得到的实验结果具有片面性,不能全面反映出磁流变材料的摩擦学性能。 First, the experimental results cannot fully reflect the friction and wear properties of magnetorheological materials. Under the action of a magnetic field, the magnetic particles in the magnetorheological material are polarized, rearranged, and fibrillated, and the viscosity and lubrication conditions of the magnetic fluid will change greatly. At this time, the friction performance of the magnetic material is significantly different from that without a magnetic field. . Therefore, the experimental results obtained under the condition of no magnetic field are one-sided and cannot fully reflect the tribological properties of magnetorheological materials.

二是实验与工程应用的相关性很差。由于磁性流体在工程中应用时往往需要在磁场的作用下才能发挥磁流变效应,因此单纯考察无磁场下磁性流体的摩擦学性能,得到的实验结果与工程应用的相关性很差。 Second, the correlation between experiments and engineering applications is poor. Since the application of magnetic fluid in engineering often needs to be under the action of a magnetic field to exert the magnetorheological effect, the correlation between the experimental results obtained and engineering applications is poor by simply investigating the tribological properties of magnetic fluid in the absence of a magnetic field.

三是现有的有场下的检测装置存在较大缺陷。 The 3rd, there is bigger defect in the existing off-site detection device.

㈠是磁场的强度较小。现有有场下的检测装置的磁场是由条形磁铁产生的,但由于摩擦磨损试验机的油盒本身形成的闭合磁路以及油盒与钢球间过大的空气间隙,磁损失严重,摩擦副接触点磁场强度仅有几十毫特斯拉,远远不能达到试验需要。 (1) The intensity of the magnetic field is small. The magnetic field of the existing detection device under the field is generated by a bar magnet, but due to the closed magnetic circuit formed by the oil box of the friction and wear testing machine itself and the excessive air gap between the oil box and the steel ball, the magnetic loss is serious. The magnetic field intensity at the contact point of the friction pair is only tens of millitesla, which is far from meeting the needs of the test.

㈡是磁场的调节不可连续进行。磁场的大小是通过改变条形磁铁与试样的距离来调节的,磁场的变化是不连续的。 (2) The adjustment of the magnetic field cannot be carried out continuously. The size of the magnetic field is adjusted by changing the distance between the bar magnet and the sample, and the change of the magnetic field is discontinuous.

㈢是投资成本较高。由于条形磁铁的价格昂贵,导致磁场发生装置的总体成本较高。 (3) The investment cost is relatively high. Due to the high price of the bar magnet, the overall cost of the magnetic field generating device is relatively high.

鉴于现有磁流变材料摩擦磨损试验现状,特提出有场下磁流变液摩擦磨损特性检测装置的研究开发。该装置的发明,解决了磁流变材料的摩擦磨损性能检测中结果具有片面性、与工程应用相关性差、现有检测装置磁场强度小、磁场强度不可连续调节、投资成本高等弊端,由于其设计理念先进、运行稳定性好、可控性能高、成本较低等优点,能有效地建立与实际工程应用相应的试验室检测条件,必将产生显著的经济效益和良好的社会效益。 In view of the current status of the friction and wear test of magnetorheological materials, the research and development of the detection device for the friction and wear characteristics of magnetorheological fluid under the field is proposed. The invention of the device solves the disadvantages of the friction and wear performance detection of magnetorheological materials, such as one-sidedness, poor correlation with engineering applications, small magnetic field strength of existing detection devices, non-continuous adjustment of magnetic field strength, and high investment costs. Due to its design concept Advanced, good operation stability, high controllability, low cost and other advantages, can effectively establish laboratory testing conditions corresponding to actual engineering applications, and will certainly produce significant economic benefits and good social benefits.
