Computer simulation of the contact of rough surfaces

Аннотация

A program for the computer simulation of the contact of two rough surfaces has been developed, which makes it possible to determine the real area of contact and the penetration of microasperities at specified parameters of microgeometry under specified loads for friction pairs with fairly soft coatings or without coatings. The model has been tested using a comparison of the results of numerical simulation with the experimental data, which has shown their good agreement. The results can be used to simulate the contact of the rough surfaces, including the case when one of these surfaces is covered with a solid-lubricating or other functional coating.
