研究人员揭示了三种可实现的摩擦定律,隶属于美国科学促进会, 本期文章:《科学》:Volume 383 Issue 6679 近日,触摸屏和机械手等许多设备都涉及到摩擦接触, we illustrate three types of achievable friction laws,可以针对性地实现特定的摩擦定律,通过优化单个凸起的高度, involve frictional contacts. Optimizing these devices requires fine control of the interfaces friction law. We lack systematic methods to create dry contact interfaces whose frictional behavior satisfies preset specifications. We propose a generic surface design strategy to prepare dry rough interfaces that have predefined relationships between normal and friction forces. Such metainterfaces circumvent the usual multiscale challenge of tribology by considering simplified surface topographies as assemblies of spherical asperities. Optimizing the individual asperities heights enables specific friction laws to be targeted.
