Study on Surface Roughness Analysis Method Using the Least-Squares Fitting for Plateau Surface Texture with Insufficient Plateau Structure.

説明

Roughness analysis methods for plateau structure surfaces have been proposed in ISO and JIS standards as well as in previous researches. However, these analysis methods cannot calculate the roughness parameters for surfaces with insufficient plateau structures. In the material probability curve (MPC), this problem is caused by the narrow plateau region found in surfaces with insufficient plateau structures. Development of a new roughness analysis method that can analyze surfaces with insufficient plateau structures is indispensable for understanding the wear progress of plateau surfaces as demanded by industry. If these problems related to the plateau surface can be solved, it can contribute to the achievement of improving engine performance and reducing automobile CO2 emissions. Therefore, the purpose of this research is to enable calculation of the roughness parameters for surfaces with insufficient plateau structure. In this research, a new analysis method using the weighted least-squares line (WLSL) was investigated and developed. The proposed method of this research succeeded in calculating the roughness parameters for surfaces with insufficient plateau structures, whose parameters could not be correctly calculated by previous methods.
