Dinamski model kadi pralnega stroja na osnovi dinamike sistema togih teles

Golob, Martin (author), Čepon, Gregor (mentor)

S pomočjo numeričnih simulacij za namen predikcije odziva in optimizacije elementov na podlagi prilagajanja mase ter togosti, želimo prikazati delovanje pralnega stroja Asko. V programskem sistemu Ansys so bile na podlagi sistema togih teles izvedene simulacije za dva kinematična modela. Prvi model brez dodane mase v bobnu in drugi z dodano maso 350 gramov. Za vsak model smo analizirali simulacije delovanja in popisali pomike posameznih delov. V prvem primeru zagon povzroča največje vrednosti pomikov posameznih delov, v drugem primeru pa se največji pomiki pojavijo po nekaj sekundah od zagona.

Abstract

With the help of numerical simulations for the purpose of predicting response and optimizing elements based on weight adjustment and rigidity, we want to show the operation of the Asko washing machine. In the Ansys software system, simulations for two kinematic models were carried out based on a rigid body dynamics. The first model without added mass in the drum and the second with an added mass of 350 grams. For each model, we analyzed the operation simulations and mapped the movements of individual parts. In the first case, startup causes maximum shift values of individual parts, and in the second case, maximum movements appear after a few seconds from startup.
