ELASTIC FOUNDATION MODEL OF ROLLING CONTACT WITH FINITE ELEMENT AND TRANSVERSAL TANGENTIAL FORCES

Abstract

The difficulties of elastic contact stress theory arise because the displacement at any point in the contact surface depends upon the distribution of pressure throughout the whole contact. To find the pressure at any point in the contact of solids of given profile there fore ,requires the solution of an integral pressure.The difficulty is avoided in the solids, can be modeled by a simple Winkler elastic foundations or “mattress” rather than an elastic half-space ,and the modulations by finite elements. When the plane of a wheel is slightly skewed to the plane of rolling described as ”sideslip” or” yaw”, transverse friction forces and moments brought into play.
