摘要
通过转化发动机缸孔珩磨表面的三维纹理特征 ,用小波分析法提取表面参数 ,并用小波变换极大模对三维内表面进行奇异特征的分解和重构 ,得到所需的形貌参数 .实验证明 ,该方法能比较准确地测量珩磨表面参数 ,有利于改进工艺 .
The 3-D texture properties of the inner surface of the engine cylinder were converted and the method for wavelet analysis could be applied to extract the parameters of the surface. The characteristics of inner surface were decomposed and reconstructed by the module maximum of wavelet transfer. The desired topography parameters were obtained. The experimental results showed that the method could be used to measure the honing parameters accurately and was helpful to improve the technology.
