Statistični popis površin s spektralnimi momenti

Podobnik Vrhovnik, Miha (author), Kalin, Mitjan (mentor)

Predstavljen je model statističnega popisa površin s spektralnimi momenti, s katerim lahko določimo nekatere lastnosti površine, kot so gostota vršičkov, radij zaokrožitve vršičkov in standardna deviacija njihovih višin. Z metodo spektralnih momentov sta bili analizirani dve realni inženirski površini in rezultati primerjani z determinističnimi modeli.

• Title: Statistical analysis of rough surfaces with spectral moments

Abstract

The statistical method of rough surface analysis using spectral moments is presented, with which topography parameters such as asperity density, summit radius and standard deviation of asperity heights of the surface can be calculated. Two engineering surfaces were analysed using spectral moments and the results were compared with deterministic models.
