dc.description.abstract | Ugao naletanja točka na šinu je značajan parametar dodira točak-šina. Zajedno sa silama koje nastaju pri tom dodiru, služi za ocenu dinamičkog ponašanja šinskog vozila pri prolasku kroz krivinu. U ovom radu je analizirana merna nesigurnost rezultata merenja specijalnim laserskim sistemom konstruisanim za merenje ugla naletanja točka na šinu, ističući značaj teorijskog pristupa pri izboru odgovarajućeg mernog principa i pri identifikaciji svih uticajnih parametara. Razmatran je i uticaj pravilnog postavljanja i pozicioniranja sistema na koloseku na rezultate merenja. Kako bi se ocenio kvalitet sprovedene analize, u radu su prikazani neki od rezultata merenja ovim uređajem i njihovo poređenje sa rezultatima dobijenim simulacijom, primenom specijalizovanog softverskog paketa VAMPIRE Pro.

dc.description.abstract | The angle of attack is an important wheel-rail contact parameter. Together with wheel-rail contact forces it serves for estimation of the rail vehicle curving performances. This paper analyses measurement uncertainty of the specially designed laser system for measurements of the wheel-rail angle of attack, with emphasis on the importance of the theoretical approach for selection of the appropriate measuring principle and for identifying all influential factors. The influence of the correct installation of the system on results is also considered. In order to evaluate quality of the analysis, some measurement results are presented and compared with the results of multibody system (MBS) simulation using specialized computer package VAMPIRE Pro. | en |
