微纳米切削可视化研究现状

当材料切削厚度达到几个原子层时,微纳米切削实验变得困难且耗时,目前的实验条件根本无法实现.而分子动力学仿真却能克服这些困难,能十分方便地改变切削条件、刀具的几何形状和加工工件材料的性质.对基于分子动力学仿真的微纳米虚拟切削基本原理及其国内外研究的现状进行阐述.介绍了几种分子动力学可视化软件.虽然目前存在很多优秀的分子动力学可视化软件,可是没有一个是针对微纳米切削的,也不能观察温度场、应力分布等信息.分析了微纳米切削可视化研究存在的问题和发展趋势,指出微纳米加工可视化将成为探索微纳米加工机理最有效的手段.

Research status of micro-nanometric cutting visualization

When the material thickness cut is a few atomic layers,micro-nanometric cutting experiment becomes more difficult and time-consuming.The current conditions is impossible.And Molecular Dynamics Simulation was able to overcome these difficulties.It can be very convenient to change the cutting conditions,the geometry of the tool and the nature of the material.In this article,the essential principle of the Molecular Dynamics Simulation and its current domestic and international research situation are expatiated...
