Abstract

An arithmetic unit that predicts a contact area or a normal force arising in a case in which two rough surfaces are in contact with each other. The arithmetic unit includes: a distribution computation section that computes from roughness distributions an asperity height distribution, which is a probability density function defining a probability of a height of an asperity peak from a reference plane being a particular height; and a contact computation section that, based on the asperity height distribution computed for each of the two rough surfaces, computes a real contact area, which is an actual contact area in a case in which the two rough surfaces are in contact, or a normal force in a case in which the two rough surfaces are in contact.
