Sažetak
Gipki mehanizam se definiše kao pokretna, materijalno koherentna struktura koja može da prenese sile i transformiše kretanje samo zahvaljujući elastičnoj deformaciji odgovarajućih segmenata strukture. Sinteza ove vrste mehanizama predstavlja izazovan zadatak, posebno zato što su njihovi elastični segmenti često izloženi velikim, nelinearnim deformacijama što zahteva znatno težu, nelinearnu analizu. Kada projektant nema unapred osmišljenu formu gipkog mehanizma za sintezu se uobičajeno koriste postupci optimizacije topologije. Preseci elemenata, koji postoje u gipkim mehanizmima dobijenim primenom postojećeg postupka optimizacije topologije, često povećavaju krutost strukture koja mora biti dovoljno elastična. U ovom radu je predstavljen novi softver za sintezu gipkih mehanizama koji unapređuje aktuelne postupke optimizacije topologije time što eliminiše presečne elemente odgovarajućih segmenata gipkog mehanizma. Metodologija koju softver koristi i njegove mogućnosti predstavljeni su na primeru sinteze gipkog hvatača i gipkog invertora pomeranja.
