A Fast Algorithm for the Simplified Theory of Rolling Contact
TLDR
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 asfast as Rolcon (Knothe).Abstract:
SUMMARY 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 “exact” program Duvorol (Kalker). Descriptions and lists of an Algol 60, and HP 67 program version are available upon request: the Fortran IV version is given in the paper.read more

A Comparison of Alternative Creep Force Models for Rail Vehicle Dynamic Analysis
Z. Y. Shen,J. K. Hedrick +1 more
TL;DR: In this paper, a comparison of alternative Creep Force Models for rail vehicle dynamic analysis is presented, and the results show that the alternative models are less accurate than the original models in terms of acceleration and acceleration.

A mathematical model to predict railway wheel profile evolution due to wear
TL;DR: In this article, a wheel wear prediction model is developed to predict the wheel profile evolution due to the wear process, which can be used to effectively evaluate maintenance intervals, to optimise wheel and rail profiles with respect to wear and to optimize the railway vehicle's suspensions with new and worn wheel profiles.

A fast wheel-rail forces calculation computer code
TL;DR: A fast algorithm and computer code for the computation of wheel-rail forces under known contact geometry and creep and spin conditions is presented and can be used instead of simple formulas to improve the accuracy or as a substitution of Kalker's programme FASTSIM to save the computation time.

Survey of Wheel-Rail Rolling Contact Theory
TL;DR: In this paper, the authors describe the theory of frictional rolling contact as far as it is significant for the wheel-rail system and give a present day account of the simplified theory and the exact linear and non-linear theory.
