Studies on the effect of surface texture on cylinder liner wear is of great importance in many research areas due to the fact that a major part of the mechanical power losses in an engine are caused by friction in the piston-cylinder liner system. Interest from both manufacturers and customers in optimizing this mechanical system seems to be similar. The surface roughness of cylinder liners plays an important role in the control of tribological properties. Cylinder liner surface topography, which affects running-in duration, oil consumption, exhaust gas emissions and engine performance as well, was taken into detailed consideration in this paper. They were measured with a stylus (Talyscan 150) or non-contact—optical (Talysurf CCI Lite white light interferometer) equipment. Precise machining process and accurate measurement equipment may not provide relevant information about surface texture properties when the procedure of processing of received (raw) measured data is not selected appropriately. This work aims to compare various type of procedures for detection and reduction of some-frequency surface topography measurement errors (noise) and consider its influence on the results of wear analysis. It was found that assessments of some extracted areas (profiles) may be much more useful than the characterization of the whole of measured details when noise was defined. Moreover, applications of a commonly-used algorithm, available in the commercial software of the measuring equipment, for measurement errors suppression may be potentially decisive in the definition of measurement noise but, simultaneously, scrupulous attention should be paid if they are implemented adequately.

缸套形貌磨损分析中基于特征的表面纹理高频测量误差抑制的改进程序

由于发动机中大部分的机械功率损耗是由活塞-气缸套系统中的摩擦引起的，因此在许多研究领域中对表面纹理对气缸套磨损的影响进行研究非常重要。制造商和客户对优化此机械系统的兴趣似乎都差不多。气缸套的表面粗糙度在控制摩擦性能方面起着重要作用。本文还详细考虑了汽缸套表面形貌，它会影响磨合时间，机油消耗，废气排放和发动机性能。用触笔（Talyscan 150）或非接触式光学设备（Talysurf CCI Lite白光干涉仪）测量它们。当没有适当地选择接收（原始）测量数据的处理的程序精确加工过程和精确的测量设备可能不提供关于表面纹理属性相关的信息。这项工作旨在比较用于检测和减少某些频率的表面形貌测量误差（噪声）的各种类型的程序，并考虑其对磨损分析结果的影响。已经发现，在定义噪声时，对某些提取区域（轮廓）的评估可能比对整个测量细节进行表征要有用得多。此外，在测量设备的商业软件中可用的用于抑制测量误差的常用算法的应用可能对测量噪声的定义起决定性作用，但是同时，
