APPLICATION OF WAVELETS TRANSFORM TO EVALUATE THE MECHANICAL SURFACE TOPOGRAPHY

Abstract

Abstract: A new method of calculation the fractal dimensions of the rough surface by wavelets transform is proposed. Based on the Weierstrass-Mandelbrot function and Majumdar-Bhushan function with known fractal dimension, it is validated that this method can calculate quite accurately the fractal dimension The fractal characterizations of the test surfaces for pool nuclear boiling experiment are evaluated by wavelets transform, the test panels are machined 5 scales roughness by rolling, sandpaper polishing and machine polishing in copper and stainless steel. The calculation results indicate the wavelets transform method is availability.

Key words: Fractal dimension, Surface topography, Wavelets transform
