20.500.12556/RUL-139026 Dinamska simulacija kontaktnih razmer pri črpalki s 3D-ozobjem Dynamics simulation of the contact conditions in a pump with 3D-gearing V magistrskem delu bomo z inženirskimi simulacijami raziskovali kontaktne razmere v črpalki med njenim delovanjem. S postavitvijo kontaktne simulacije poskušamo priti do čim bolj realnih lokacij in velikosti kontaktnih obremenitev v ozobju črpalke in drugih drsnih površinah. Reševanja se lotimo z metodo končnih elementov. Postavimo tri simulacije, ki se med seboj razlikujejo glede na časovno odvisnost ter tip obremenitve. Prva simulacija je kvazi-statična z integriranimi obremenitvami. V drugi simulaciji vpeljemo rotacijo črpalnih elementov z integriranimi obremenitvami. V tretji simulaciji črpalne dele izpostavimo pogojem, ki izhajajo iz tokovnih simulacij na tej črpalki. Rezultati simulacij pokažejo, da se največji kontaktni tlaki pojavijo na 3D-ozobju, spodnjem robu drsnega ležaja ter na linijah v oblikovni zvezi. Mesta kontaktov v simulacijah v veliki meri sovpadajo z mesti dejanske obrabe črpalnih delov. In the master’s thesis engineering simulations are applied to investigate the contact conditions in the pump during its operation. By setting up a contact simulation, we try to realistically estimate the locations and magnitudes of contact loads in the pump gearing and other sliding surfaces. The analysis is performed with the finite element method. We set up three simulations that differ in terms of time dependence and type of load. The first simulation is quasi-static with integrated loads. In the second simulation, the rotation of pumping elements with integrated loads is introduced. In the third simulation, the pump parts are exposed to the conditions resulting from the flow simulations on this pump. The results of the simulations show that the highest contact pressures occur on the 3D-gearing, the lower edge of the plain bearing and on the lines in the design connection. The contact locations in the simulations coincide well with the actual wear locations of the pump parts. črpalka s 3D-ozobjem kontaktne simulacije dinamične simulacije ANSYS Mechanical povezava CFD-FEM mehanska obraba pump with 3D-gearing contact simulations dynamic simulations ANSYS Mechanical connection CFD-FEM mechanical wear true false false [P.
