| 5 | 超滑与摩擦起源的探索显示文摘摩擦消耗掉全世界约1/3的一次能源,磨损致使大约80%的机器零部件失效,每年因摩擦、磨损造成的经济损失约占国内生产总值(gross domestic product,GDP)的2%~7%.对于中国这样的制造大国,摩擦、磨损造成的损失占比较高.仅以5%计算,2019年我国因摩擦、磨损造成的损失就可能达4.95万亿元.因此,如何减少摩擦、降低磨损是大家广为关注的问题,也是影响人类社会走向绿色、环保、有效利用资源和能源的关键因素之一.探索摩擦起源,实现超滑状态成为摩擦学研究的重大使命.超滑就是将摩擦系数呈数个数量级的降低,同时伴随磨损率呈数量级下降的一种新技术.本文重点介绍了我们课题组近期在超滑和微观摩擦能量耗散机制方面的研究进展,同时也对国内外相关研究进行了简要评述. | 雒建斌 | 2020 | 科学通报2020,65,27: | 8 |
| 6 | Characteristics of lubrication at nanoscale in two-phase fluid system显示文摘Thin film lubrication (TFL) is a condition in which the lubricating features between two surfaces in relative motion are determined by the combination of the properties of the surfaces and the lubricant and viscosity of the lubricant. The effects imposed by couple stress on lubrication characteristics cannot be disregarded in this regime where the ordered molecules dominate the fluid field. There are different tensor measures and constitutive equations in this case other than Newtonian case. The lubrication of two-phase (solid phase and liquid phase) fluid is investigated in this paper. The existence of couple stress will enhance the lubricant viscosity and hence increase the film thickness and improve the load-carrying capability. Size-dependent effects can be seen in the lubrication with couple stress, and the thinner the lubricating film is, the more obvious the effect will be. | 张朝辉 温诗铸 雒建斌 | 2002 | Science China Chemistry2002,45,2: | 6 |
| 7 | Molecular behaviors in thin film lubrication——Part two: Direct observation of the molecular orientation near the solid surface显示文摘Over the past twenty years, thin film lubrication(TFL) theory has been used to characterize the molecular behaviors in lubrication films thinner than 100 nm, effectively bridging the gap between elastohydrodynamic lubrication and boundary lubrication. Unfortunately, to date, the TFL molecular model proposed in 1996 has not been directly proven by experimental detection. Herein, a method based on surface-enhanced Raman spectroscopy was developed to show both the packing and orienting of liquid molecules in the TFL regime. By trapping liquid crystal molecules between a structured silver surface and a glass surface, molecular ordering states dominated by shear effect and surface effect were successfully distinguished. A nanosandwich structure consisting of an adsorbed layer, an ordered-molecule layer, and a fluid layer was demonstrated. Molecule imaging in TFL was achieved. Our results illustrate the molecular behaviors and lubrication mechanism in nanoconfined films and facilitate the lubrication design of nanoelectromechanical and microelectromechanical systems. | Ming GAO Haoyu LI Liran MA Yuan GAO Linwei MA Jianbin LUO | 2019 | Friction2019,7,5: | 5 |
| 8 | 高铁桥梁支座的电控摩擦减隔震技术研究进展显示文摘针对普通高铁桥梁支座在高烈度地震发生时无法起到有效减隔震作用的问题,本文综述了高铁桥梁支座的减隔震机理、支座球面滑板摩擦磨损性能、润滑条件下电控摩擦机理的一些研究进展。发现该领域还面临着的主要问题是润滑填充物与球面滑板材料相容性较差、球面滑板表面微织构加工的精密度较低、电场调控摩擦系数的准确性不高。未来应完善聚四氟乙烯球面滑板填充复合与表面织构化的协同减摩抗磨机理、建立硅脂润滑条件下摩擦系数的电场主动控制机理,以期满足高铁桥梁支座在常规状态下具有低摩擦磨损,且在高烈度地震中通过电场主动调控摩擦阻尼来增大地震能量耗散的减隔震设计要求。 | 王永芳 李重阳 孙秀怀 王守仁 王高琦 | 2021 | 山东工业技术2021,,4: | 0 |
