THE TRAIN IN CURVE: ADDITIONAL POWER LOSSES
Abstract
The article assesses relationship between friction forces in the contact area of wheelset and rail and the features of track curve. The study has been developed on the basis of Euler formula that establishes a ratio of forces in a pair rope – cylinder (capstan). Theoretical analysis argues under certain conditions in favor of positive outlook of modular trains (see also the article by the same author in previous issue of Mir Transporta (World of Transport and Transportation) Journal, 2013, Vol. 49, Iss. 5, pp.28–37 taking into account editorial remark on the necessity of comprehensive study of the subject).
