Abstract

U ovom radu prikazana je numerička analiza i topološka optimizacija umjetnog kuka. Unutar rada istraženi su materijali koji se koriste danas za izradu cijelog umjetnog kuka i metoda topološke optimizacije. Provedena je numerička analiza umjetnog kuka u skladu s normu u ISO 7206, te je utvrđeno kako su zadovoljeni svi uvjeti čvrstoće. Problem nedovoljne osteointegracije umjetnog kuka s bedrenom kosti nije toliko rijedak pa se provela topološka optimizacija kako bi se dobio veći broj kontaktnih površina za osteointegraciju. Topološka optimizacija se provela uz tri različita uvjeta smanjivanja volumena, u prvom 75%, drugom 65% i trećem 55% volumena optimiranog dijela.

Abstract (english)

This paper presents a numerical analysis and topological optimization of an artificial hip. The study examines the materials currently used in manufacturing and the method of topological optimization. A numerical analysis of the artificial hip was conducted in accordance with the ISO 7206 standard, confirming that all strength requirements were met. The issue of insufficient osseointegration of the artificial hip with the femoral bone is not uncommon. Therefore, topological optimization was carried out to increase the number of contact surfaces for osseointegration. The optimization was performed under three different volume reduction conditions: 75%, 65%, and 55% of the optimized part’s volume.
