摘要:

多尺度表面中,不同加工过程形成的纹理成分具有不同的粗糙度尺度和性能。多尺度表面形貌的功能评定,关键是识别不同的纹理成分,描述其功能属性。基于概率曲线和支承率曲线,提出一种多尺度表面形貌的功能评定方法,并研究了表面形貌的加工控制问题。对平台珩磨缸套表面的功能评定与控制研究表明,这种多尺度表面的功能评定方法是可行的。以ISO13565-3粗糙度参数为纽带,建立联系表面功能与加工工艺的经验模型,可以实现面向功能的表面质量控制。

Abstract:

Due to the fact that different components of texture generated by different manufacturing processes has different scales and tribological properties,the key to functional assessment of multi-scale surfaces is to identify roughness components and to describe their functional properties.A method of assessing the functional properties of multi-scale surface was presented based on material probability curve and material ratio curve,and manufacturing control to meet the functional requirements for surface was investigated.Application to plateau honed cylinder liner suggests that the method is effective,and manufacturing quality control can be achieved providing that an empirical model relating surface performance and manufacturing process is developed by means of roughness parameters defined in ISO13565-3.
