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. WebbCONTACT [Vollebregt 2014] include the implementation of a falling friction law and the implementation of an elastic interfacial layer. Likewise, in the simplified theory of rolling contact, which is implemented in the algorithm FASTSIM [Kalker 1982], the influence of water can be considered by adjusting the coefficient of friction in terms of BL.
WebbSUMMARY An algorithm “Fastsim” for the simplified theory of rolling contact is described which is 15-25 times as fast as the existing programs Simrol (Kalker), and 3 times as fast as Rolcon (Knothe). The relative total force computed with Fastsim differs at most 0.2 from that calculated with Simrol, Simcona (Goree & Law), Rolcon, and the ...
