摘要:
介绍了机械结合面的基本概念。一台机床90%以上的阻尼来自机械结合面。影响机械结合面特性的因素众多，且多为非线性性质。对机械结合面的几种常用接触模型如统计模型、分形模型、有限元模型、试验模型进行了比较全面的回顾和评述，详细地论述了相应模型的优点、存在的问题和应用范围。最后指出了还没有妥善地解决好机械结合面一系列最基本的问题。The basic concept about mechanical joint surface was introduced. More than 90% of damping in a machine tool comes from mechanical joint surface. There are many factors that affect the characteristics of mechanical joint sur-face, most of which are nonlinear. Some contact models in common use, for example statistical model, fractal model, finite element model and experimental model were relatively generally reviewed. Their advantage, existing issue and application range were discussed in detail. At last, some most basic problems unsatisfactorily solved were pointed out.
