| Summary: | The paper deals with the strength analysis of structural devices(platform bridges) that fasten cars to a car carrier frame. Theloads of all bridges are evaluated along with the indication ofthe areas of load concentration. The paper presents a brief structuraldescription of platform bridges, including their drawingsperformed with the help of SolidWorks software. The bridgeloads have been analyzed applying Ansys software. Accordingto the results of computer simulation of the loads, dangerousstructural areas of the bridges have been identified. While makingattempts to solve the established structural problems of suchcar carriers, suggestions for their structural improvement havebeen put forward, and computer simulation of loads and stressspread have been performed. The paper ends with conclusionsand suggestions.

Straipsnyje atliekamas automobilio tvirtinimo prie automobilvežio rėmo konstrukcinio elemento (platformos tiltelio) stipruminis tyrimas. Nustatoma tiltelį veikianti apkrova bei apkrovos koncentracijos vietos. Straipsnyje trumpai aprašomi tiltelio konstrukciniai elementai ir, naudojant „SolidWorks“ programinį paketą, braižomas pats tiltelis. Tiltelio konstrukciją veikiančios apkrovos tiriamos „Ansys“ programiniu paketu. Pagal atlikto apkrovų modeliavimo rezultatus patvirtinamos pavojingos konstrukcinės tiltelio zonos. Siekiant išspręsti nustatytą konstrukcinę automobilvežio platformos elemento problemą, pasiūlytas konstrukcijos tobulinimas, atliktas šios konstrukcijos apkrovų ir įtempimų pasiskirstymo modeliavimas. Formuluojamos išvados bei pasiūlymai.
Reikšminiai žodžiai: automobilvežis, rėminė konstrukcija, platformos tiltelis, baigtinių elementų metodas, apkrova, įtempimas. |
