A quasi-static pendulum, a modified dynamic pendulum with adjustable rod length, and the SPH (Smooth Particle Hydrodynamics) model Tis Isat were applied to simulate liquid oscillations. A simplified vehicle-tanker overturning model was developed and applied in order to determine the overturning threshold for the first manoeuvre. The agreement of liquid oscillations between the applied methods was better in the second manoeuvre, while the maximum inclination of the liquid gravity centre was successfully simulated in both cases. Both dynamic methods, the SPH and the dynamic pendulum, show a significantly lower overturning threshold, while all methods show similar overturning behaviour for a vehicle with liquid cargo. The threshold computed using the SPH model is slightly higher than with the dynamic pendulum due to wall-particle and particle-particle interactions. The results and comparisons confirm the suitability of the SPH method for simulating sloshing in road tankers and also show the method%s advantages: realistic description of the non-linear free surface in real-time, along with a consideration of mixing and friction processes within the fluid"},{"@xml:lang":"sl","#text":"V prispevku obravnavamo pljuskanja kapljevine v cisterni krožnega prečnega prereza med dvema tipičnima manevroma: vstopom in vožnjo skozi krožišče ter menjavo voznega pasu. Za simulacije nihanja kapljevine smo uporabili tri metode: modela kvazistatičnega nihala in modificiranega dinamičnega nihala s spremenljivo ročico ter model Tis-Isat, ki deluje po metodi hidromehanike zglajenih delcev (SPH - Smooth Particle Hydrodynamics). Za določitev praga prevrnitve pri prvem manevru smo izdelali in uporabili model poenostavljenega vozila s cisterno. Ujemanje nihanja kapljevine je bilo boljše pri drugem manevru, maksimalni odmik težišča kapljevine pa smo uspešno simulirali v obeh obravnavanih primerih. Vse tri metode pokažejo podobno obnašanje vozila s tekočim tovorom ob prevrnitvi, obe dinamični metodi, SPH in dinamično nihalo, pa dajeta znatno nižji prag prevrnitve. Pri SPH je prag prevrnitve nekoliko višji kot pri dinamičnem nihalu zaradi interakcije med delci kapljevine ter kapljevino in ostenjem. Primerjava rezultatov dinamičnih metod potrjuje uporabnost metode SPH za simulacije pljuskanja v tovornih cisternah, prav tako pa tudi prednosti metode SPH: opis nelinearne proste gladine v realnem času ter upoštevanje viskoznih procesov in mešanja v kapljevini"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-6AIF9C8A","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-6AIF9C8A"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-6AIF9C8A/d9c7343e-022b-48d2-b370-e60f7991ebd9/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-nc-sa/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-6AIF9C8A/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-6AIF9C8A"}}}}
