Abstract

U ovom radu provedena je numerička i analitička analiza konstrukcije stalka za motor. Već izrađeni i rabljeni stalak u automobilskom servisu je izmjeren te je napravljen njegov trodimenzionalni model u programskom paketu Solidworks. Zatim je provedena verifikacija konačnih elemenata koji su korišteni za analizu na jednostavnijem primjeru prostorne gredne konstrukcije. Također je ispitana i konvergencija rješenja. Nakon verifikacije provedena je analiza stalka za motor opterećenog masom samog motora i momentom pritezanja. Numerička analiza provedena je korištenjem programskog paketa Abaqus koji se temelji na metodi konačnih elemenata. Dok je analitički proračun napravljen korištenjem matrične metode te je izvršena usporedba rezultata. Na kraju je na temelju rezultata i njihove usporedbe iznesen zaključak te su navedena moguća poboljšanja konstrukcije stalka za motor.

Abstract (english)

In this paper numerical and analytical analysis of engine stand has been conducted. Engine stand used in car repair shop was measured then the three dimensional model of a stand was made in a software package Solidworks. Afterwards, verification of used finite elements has been made on a simple example of a space beam structure. Also, convergence of results was tested. After verification analysis of engine stand loaded with the mass of an engine and with tightening torque has been made. Numerical analysis has been conducted by using a software package Abaqus, this software is based on a finite element method. Analytical calculation has been made using the matrix method and the results are compared. In the end conclusion is made based on the results and their comparation and possible improvements of engine stand are discussed.
