Role of Bearings in Mechanical Engineering Appliions - …

Bearings are machine elements that allow components to move with respect to each other. There are two types of bearings: contact and non-contact. Contact-type bearings have mechanical contact with equipment, which includes sliding, rolling, or flexural bearings. Non-contact bearings include liquid, air, mixed phase, and magnetic bearings.

Mechanical Engineering Tribology Laboratory - Purdue University Mechanical Engineering

The dynamic bearing model (DBM) was developed based on the discrete element method to accurately model different types of bearings. The rolling elements, cage, and races are each rigid bodies. Hertzian contact theory governs normal contact between the bearing elements, with several friction models available to determine the friction forces on each element.
