Študija vpliva zamika lukenj za vijake na mehanski odziv vijačenih preklopnih spojev : magistrsko delo

Bevk, Uroš (author), Može, Primož (mentor), Zoubek, Sara (comentor)

V magistrskem delu je obravnavana parametrična analiza vijačenih preklopnih spojev. V okviru parametrične analize se preučuje vpliv zamika lukenj za vijake na mehanski odziv spojev z različnimi lastnosti geometrije ter različnimi materialnimi lastnostmi pločevin (jekla S355 ter S960) in vijakov (kvaliteta 5.6 ter 10.9). Mehanski odzivi spojev, obravnavanih v parametrični analizi, so bili pridobljeni z numeričnimi izračuni na modelih, pripravljenih v programu Abaqus. V dokument je zato dodan podroben prikaz in opis postopka priprave ter kontrole odzivov numeričnih modelov spojev. Izsledki parametrične analize nakazujejo, da zamiki v poziciji lukenj lahko pomembno vplivajo na nosilnost vijačnih preklopnih spojev. V rezultatih parametrične analize pa je bil opažen zanimiv vzorec znižanja nosilnosti pri spojih, ki imajo visoke vrednosti razmerja med premerom vijaka in debelino pločevin.

• Title: Study on effects of bolt hole misalignments on mechanical response of bolted lap joints

Abstract

This thesis presents a parametric study of bolted lap connections. The study investigates the influence of misalignments in bolt hole position on the mechanical behaviour of bolted lap connections with varying geometric properties and material properties of steel plates (steel grades S355 and S960) and bolts (grades 5.6 and 10.9). The joint responses evaluated in the parametric study were obtained from simulations performed using numerical models in Abaqus. A detailed description of the procedures used for model development and verification of model behaviour is therefore included in the document. The results show that misalignments in bolt hole position can have significant effects on joint resistance. An interesting pattern was also observed in the parametric study results, where resistance decreases significantly in joints with higher ratios of bolt diameter to plate thickness.
