| 中文摘要: |
| 磁流变液（Magnetorheological fluid, MRF）是一种形态和性能受外加磁场控制的新型智能材料。在汽车、建筑、医疗、航空航天多种领域具有重要的应用价值，但磁流变液沉降性问题一直是影响其广泛应用的难题。因此，首先从载液、磁性颗粒和添加剂三方面出发，简要回顾了近几年在磁流变液沉降性方面的研究，指出了影响磁流变液沉降性的因素主要有：载液的黏度、磁性颗粒的形状和尺寸、磁性颗粒与载液之间的密度差、添加剂的种类与添加量等。并给出了有效提高磁流变液沉降性的可行策略，最后从磁流变液的沉降现象与应用方面对沉降性进行了展望。 |
| 英文摘要: |
| Magnetorheological fluid (MRF) is a new type of smart material whose morphology and properties are controlled by an external magnetic field. It has important application value in the fields of automobile, construction, medical treatment and aerospace. But the sedimentation of magnetorheological fluid has always been a difficult problem affecting its wide application. Therefore, starting from the three aspects of carrier liquid, magnetic particles and additives, the research on the sedimentation of magnetorheological fluids in recent years is briefly reviewed, and it is pointed out that the main factors affecting the sedimentation of magnetorheological fluids are: The viscosity of the carrier fluid, the shape and size of the magnetic particles, the density difference between the magnetic particles and the carrier liquid, the types and amounts of additives, etc. The feasible strategies to effectively improve the sedimentation of magnetorheological fluids are given. Finally, the sedimentation of magnetorheological fluids is prospected from the perspective of sedimentation phenomena and applications. |
