WebbIn the simplified theory of rolling contact, introduced by Kalker in 1973, this complicated relation is replaced by the assumption that the surface displacement at a point x depends linearly on the surface traction at the same point x only.

WebbA Fast Algorithm for the Simplified Theory of Rolling Contact. SUMMARY An algorithm “Fastsim” for the simplified theory of rolling contact is described which is 15-25 times … WebbSix theories are significant at present: (1) the two-dimensional theory of Carter (1926); (2) the linear theory (Kalker 1967); (3) the complete theory (CONTACT, Kalker 1983–1990); (4) the British Rail Table Book (ca. 1980); (5) the theory of Shen, Hedrick and Elkins (1984); (6) the simplified theory (Kalker, 1973–1989).
WebbIn the present paper three problems in the simplified theory of rolling contact are investigated. As to the first problem, three benchmark loadings, derived by kalker in 1973 for hertzian rolling contact, are in existence. Each of these loadings gives rise to a value of the flexibility parameter of the simplified theory. WebbSIMPLIFIED THEORY OF ROLLING CONTACT. Author KALKER JJ SUBDEP. MATH., DELFT UNIV.

They are the linear theory of rolling contact and the simplified theory of rolling contact [6]. The linear theory concerns cases where wheel creepage is small, such that the entire contact area is assumed to be in adhesion. That is, no slip occurs throughout the contact patch. fisher detailingWebbEngland is a country that is part of the United Kingdom.
