Original abstract

In this work, the thermal elastohydrodynamic lubrication (TEHL) in an impact motion is explored using multigrid (MG) method and column by column scanning techniques. A steel ball impacts onto an infinite steel plane lubricated with a thin layer of oil. The study starts from a smooth contact problem and the results are compared with the corresponding isothermal ones. Then surface waviness is imposed on the steel ball surface to check the fluctuation in the oil film.

Czech abstract

Článek shrnuje výsledky numerického studia multigridní metody pro případ dopadu ocelové kuličky na ocelovu desku mazanou tenkou vrstvou oleje. Vliv tepelných dějů je studován zpočátku na hladkém kontaktu, kdy jsou výsledky srovnány s řežením izotermickým. Poté je použita nerovnost na kuličce k studiu vlivu povrchových nerovností na utváření mazacího filmu.
