Apstrakt

U reciklažnoj industriji kao ulazna sirovina koriste se usitnjeni materijali različitog sastava i karakteristika. Shodno tome, u ovom radu, akcenat je stavljen na sagledavanju uticaja konstrukcijskog rešenja i inženjerskog dizajna sekača, kroz razvoj adekvatnih mehaničko matematičkih modela i same praktične realizacije, na mogućnost usitnjavanja. Usitnjavanje materijala rešava veoma bitne probleme po pitanju zaštite životne sredine. Hidraulični sekač sa dva vratila može se efikasno koristiti za primarno usitnjavanje (komunalnog i industrijskog otpada, jedno ili više komponentnog otpada) i sekundarno usitnjavanje (mineralnih sirovina). U radu su predstavljena istraživanja modeliranja šasije pomenutog sekača za usitnjavanje betona, gume, plastike i drveta, kao i uticaj konstruktivnog rešenja šasije na mehaničko opterećenje vratila. Kreiranje trodimenzionalnog geometrijskog modela šasije i formiranje mreže metode konačnih elemenata izvršeno je programskim paketom ANSYS MECHANICAL APDL.
