diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje Strojništvo
Abstract
V diplomskem delu so predstavljene smernice, ki jih je priporočljivo upoštevati pri konstruiranju lahkih hidravličnih blokov iz aluminijevih zlitin. Opredeljene in opisane so vrste aluminijevih zlitin, ki so najprimernejše za njihovo izdelavo. V nadaljevanju dela so predstavljeni hidravlični bloki na splošno, prikazana pa je tudi zgradba njihovih notranjih povezav - izvrtin, med katerimi se pojavljajo trdnostno kritična mesta. Omenjeno je tudi aktualno stanje tehnike na tem področju. Izbrana je oblika preizkušancev za izvedbo preizkusov. Izvedena je napetostno-deformacijska analiza različnih modelov preizkušancev, tako tistih, ki vsebujejo le dve vzporedni izvrtini kot tudi tistih, ki imajo dodatno prečno izvrtino za dostop do predvidenega merilnega mesta. Na osnovi rezultatov MKE analiz je izbrana najprimernejša oblika prečnih izvrtin. V eksperimentalnem delu so opravljeni statični porušitveni testi preizkušancev brez prečnih izvrtin. Do dejanske statične odpovedi stene med vzporednima odprtinama v preizkušancu je prišlo le pri preizkušancu, pri katerem je bil razmik med izvrtinama zmanjšan na 0,28 mm.

Secondary title: |
Determination of the critical cross section of an aluminium hydraulic manifold |
Secondary abstract: |
In the thesis are presented the guidelines that are recommended to follow when constructing the light hydraulic manifolds out of aluminum alloys. Defined and described are the types of aluminium alloys, most suitable for their production. In the continuation of this work, hydraulic manifolds are presented in general, and the construction of their internal connections-bores, in between which the strength-critical spots appear, are displayed. Mentioned is also the condition of the technology that is today being used in this field. The shape of the specimens for the tests is chosen. The stress-strain analysis is conducted on different types of specimens - on those that contain only two parallel bores as well as those with an additional transverse bore for access to the estimated measurement spot. Based on the results of FEM analysis, the most suitable shape of the transverse bore is chosen. At the experimental part, the static failure tests of the specimens without transverse bores are conducted. The actual static failure of the wall between parallel openings in the specimen occurred only at the specimen, in which the distance between the bores was reduced to 0.28 mm. |
