Hertzian force law

Witryna15 cze 2024 · 2.1 Introduction. When two elements with curved surfaces make contact with each other and are pressed together, contact stresses (also called Hertzian contact stresses) are developed within the contact areas. Practical examples include the contact between wheels and rails, valve cams and tappets, mating gears and rolling bearings. WitrynaA new regularisation of non-elliptical contact patches has been introduced, which enables building the look-up table called by us the Kalker book of tables for non-Hertzian …
