Uticaj ramena čepa na čvrstoću spoja ovalni čep-žljeb

Abstract

U radu su prikazani rezultati uporednog ispitivanja čvrstoće spojeva ovalni čep-žljeb kod dve grupe proba. Spojevi grupe A, izrađivani su sa oba ramena čepa, dok su spojevi grupe B izrađivani bez donjeg ramena čepa. Ispitivanje čvrstoće, sprovedeno je na spojevima bočnog sarga i zadnje noge stolice. Rezultati istraživanja su pokazali da spojevi grupe A imaju veću prosečnu vrednost momenta savijanja u odnosu na spojeve grupe B, ali statističkom analizom nije potvrđena značajnost razlike u čvrstoći između ove dve grupe spojeva.

This paper presents the results of a parallel examination on the strength of oval tenonmortise joints in two groups of test joints. Joints from group A were made with both shoulders of tenon, while joints from group B were made without the lower shoulder. Examination of strength was conducted on a chair joints rear leg-rail. The results of the examination indicated that joints in group A had a higher average bending moment capacity in comparison with the joints in group B. However, the significance of difference in strength between the two groups of joints was not confirmed by the statistical analysis.
