摩擦力的一般特性与做功特性分析

The Analysis About General Characteristic and Work Characteristic of Friction

分析了在经典力学中导致摩擦力复杂因素的内在机制和各种特性,讨论了滑动摩擦力与滚动摩擦力的特性差异和广义可比关系,给出了目前仍引起争论的一些问题的简要分析,研究表明:滑动摩擦作用主要来自凸出的相互接触点弹性形变的剪切应力以及分子间的相互作用.摩擦力做功与参照系的相关性与研究的视点有关.

Characteristic and mechanism of friction, which result in series complex factor, are discussed. The interrelation of both glide-friction and roll-friction are compared. The some argued question are briefly analysed. Show :The glide-friction effect mostly comes from cut-stress of touch part and reciprocity between molecules. The relativity about consult system and friction work is related to point of view of study.
