中文摘要:
      目的 准确测量连杆衬套表面粗糙度。 方法 采用高斯滤波法和小波分析法两种方法对连杆衬套表面粗糙度进行评定,并将评定结果与实测结果作对比。 结果 高斯滤波和小波法的相对误差分别为 1 . 7046% 和 0 . 9037% 。 结论 采用高斯滤波和小波分析评定连杆衬套的表面粗糙度都具有可行性,相比之下,小波法的评定结果更为准确。
英文摘要:
      Objective To measure the surface roughness of connecting rod bushings accurately. Methods Use the methods of gaussian filter and wavelet analysis to evaluate the surface roughness of connecting rod bushings, and compare the evaluation results with the measured results. Results The respective relative error of Gauss filter and wavelet method was 1 . 7046 % and 0 . 9037 % . Conclusion It was verified that both the gaussian filter and wavelet analysis were feasible for the evaluation of the surface roughness of connecting rod bushings, and the evaluation methods of the wavelet method were more accurate.
