当器件尺寸变得很小时,相对于弹力,惯性力就显得不重要.从理论上详细研究了两个小的接触运动体可以视为刚体时的极限情况下所出现的动力学现象.得出了一种新的基于运动学原理的运动接触机理,它有着与传统接触理论完全不同的特性.研究表明,诸如MEMS之类小型装置的动力学特性能很好地服从这种新的运动学理论,且应用这种新的机理能有助于防止摩擦中出爬行. When the size of the device becomes very small, the inertial force is less important than the elastic force, and the kinetic phenomenon that occurs when the two small contact moving bodies can be considered as rigid bodies is theoretically studied in detail. A new kinematic mechanism based on kinematic theory, which has completely different characteristics from the traditional contact theory, shows that the dynamics of small devices such as MEMS are well suited to this new kinematic theory , And applying this new mechanism can help prevent creeping out of friction.
