The influence of vehicle parameters on curve resistance for various track parameters
Tato práce se zabĂ˝vá problematikou jĂzdy a postavenĂ ĹľelezniÄŤnĂch vozidel v oblouku koleje a odporu z jĂzdy obloukem koleje. Prvnà část práce se vÄ›nuje teoretickĂ©mu rozboru jĂzdy obloukem, popisem odporu pĹ™i jĂzdÄ› obloukem, popisem parametrĹŻ vozidla a trati majĂcĂch vliv na odpor z jĂzdy obloukem. Dále je popsána Heumannova metoda, která se problematikou jĂzdy obloukem zabĂ˝vá. V druhĂ© části je popsán a znázornÄ›n graficko-poÄŤetnĂ postup Ĺ™ešenĂ postavenĂ vozidla v oblouku koleje a zjištÄ›nĂ velikostĂ Ĺ™ĂdĂcĂch sil. Tato pĹŻvodnĂ metoda rozšĂĹ™ena o numerickou metodu, pomocĂ nĂĹľ jsme schopni zobrazovat závislost odporu z jĂzdy obloukem na poĹľadovanĂ˝ch parametrech vozidla a trati.This work deals with the issue of driving and the positioning of railway vehicles on curved tracks and the resistance of driving around curves. The first part of the work focuses on the theoretical analysis of driving around curves, describing the resistance encountered during curve driving, and outlining the parameters of the vehicle and track that affect the resistance of driving around curves. Additionally, the Heumann method, which deals with the issue of driving around curves, is described. In the second part, a graphical-computational procedure for solving the positioning of the vehicle on curved tracks and determining the magnitudes of the controlling forces is described and illustrated. This original method is expanded by a numerical method, through which we are able to display the dependence of the resistance of driving around curves on the desired parameters of the vehicle and track.DopravnĂ fakulta Jana PerneraStudent pĹ™ednesl obhajobu bakalářskĂ© práce.
