CONTACT PROBLEM ANALYSIS BY USING OF FINITE ELEMENT METHOD

U radu je izvršena analiza odabranog kontaktnog problema primjenom metode konačnih elemenata. Odabrani kontaktni problem je spoj s razrezanom steznom glavinom sa zarezom na jednom kraju. Programski paket koji je korišten za analizu metodom konačnih elemenata je Ansys Workbench. U prva četiri poglavlja dane su osnove nelinearne analize primjenom metode konačnih elemenata. Iznesene su i osnove kontaktnih nelinearnosti kao i vrste kontakata koje su primijenjene u programskim paketima Ansys Workbench i Ansys Mechanical APDL. Za odabrani kontaktni problem dana je osnovna teorija s analitičkim izrazima za proračun. Zatim je proveden analitički proračun i analiza metodom konačnih elemenata čije su vrijednosti međusobno uspoređivane. Provedena je i dodatna usporedba za glavčinu sa zarezom i bez zareza pomoću metode končanih elemenata. Ispitana je raspodjela tlaka s obzirom na različite krutosti glavine i stupa.This paper presents an analysis of the selected contact problem by using the finite element method. The contact problem in question is a clamping connection with a slotted hub which has a one-sided cut. The software package used for the analysis, using the finite element method, is Ansys Workbench. In the first four sections, the basis of the nonlinear analyses using the finite element method as well as the basics of nonlinearity of contacts and the types of contacts used by Ansys Workbench and Ansys Mechanical APDL were presented. Basic theory and analytical solutions were given for the selected problem. Afterwards, analytical solution is performed along with the finite element analyses and the comparison of both results. Additional analyses were conducted between the hub with and without a one-sided cut using the finite element method. Pressure distribution, regarding the different stiffness of the hub and the column, has also been analyzed
