Abstract
Ovaj završni rad na temu “Analiza dinamike glavnog vretena tokarilice prilikom tokarenja asimetričnih izradaka“ se sastoji od teorijskog uvoda u znanost o vibracijama i metode konačnih elemenata, te praktičnog zadatka koji se sastoji od dva dijela: analize dinamike sklopa vretena i stezne glave te analize prisilnog odziva navedenog sklopa kada na njega djeluju rotacijske sile uslijed tokarenja neuravnoteženog izratka. U praktičnom dijelu rada napravljena je modalna analiza navedenog sklopa koja je rezultirala listom od prvih 10 vlastitih frekvencija. Dobiveni rezultati su potkrijepljeni drugom analizom, analizom prisilnog odziva sklopa vretena i stezne glave zbog sila uzrokovanih tokarenjem asimetričnog izratka. Kao što je očekivano na osnovu navedene teorije iz početnih poglavlja, najveće vrijednosti deformacija i naprezanja se javljaju pri brzinama vrtnje koje se poklapaju s vlastitim frekvencijama.
Abstract (english)
This thesis titled „Dynamic analysis of the main spindle of a lathe when turning asymmetrical workpieces“ consists of a theoretical introduction to science of vibration and science of finite element method used in subsequent analyses, and a practical task composed of two parts: lathe spindle dynamics analysis and harmonic response analysis of an assembly composed of spindle, power chuck jaw and said asymmetrical workpiece. The practical part of this thesis consists of a modal analysis of the aforementioned assembly which resulted in a list of the first 10 natural frequencies. The results acquired in the first analysis were corroborated by another, harmonic response analysis of the same assembly, but coupled with the assymetrical workpiece, i.e. the equivalent forces that it produces when rotating. As expected from the theoretical background laid out in the foremost chapters, the largest deformations and stresses occured during rotating speeds equivalent to natural frequencies of the assembly.
