Abstract
SAŽETAK Radom je prikazan numerički proračun čvrstoće podvozja zrakoplova, koje predstavlja jedan od najkritičnijih dijelova čitave zrakoplovne konstrukcije. Dimenzije CAD modela prednjeg podvozja odgovaraju stvarnim dimenzijama prednjeg podvozja. Rubni uvjeti i opterećenje, nužni za provedbu ove analize određeni su iz poznatih podataka o zrakoplovu Piper Arrow IV, dok je materijal podvozja pretpostavljen. Opterećenje podvozja nastaje kao posljedica udarca u pistu pri slijetanju. Tetraedarski konačni elementi korišteni u analizi verificirani su na problemu 3D nosača, a pritom je prikazan i analitički proračun istog. Također je prikazana usporedba numeričkih i analitičkih rezultata na problemu 3D nosača. Provedbom numeričke analize podvozja verificiranim konačnim elementima u programskom paketu Abaqus te postavljanjem različitih mreža na model podvozja pokazano je da osovina predstavlja kritičan dio čitave konstrukcije te je prikazana konvergencija rješenja na istoj. Također je priložen grafički prikaz pomaka modela i pripadna naprezanja. Iz dobivenih iznosa naprezanja slijedi da konstrukcija podvozja zadovoljava uvjet čvrstoće uz pripadni faktor sigurnosti. Na kraju je dan zaključak koji se temelji na dobivenim rezultatima.
Abstract (english)
SUMMARY Numerical analysis of airplane undercarriage firmness is presented in this thesis. Airplane undercarriage is one of most critical parts of whole airplane. Dimensions of front undercarriage CAD model match those of real undercarriage. Boundary conditions and load are necessary for this analysis and are determined from Piper Arrow IV airplane dana. Undercarriage material is assumed. Undercarriage load is consequence of hitting the runway during landing. Tetrahedral finite elements used in analysis are verified on 3D beam problem. Analytical calculation of beam is shown as well. Comparison of 3D beam numerical and analytical results is shown as well. It is concluded that undercarriage axle represents critical part of whole construction by implementing verified finite elements and different finite element grids in numerical analysis of undercarriage carried out in Abaqus software. Convergence of solution on axle is also shown. Graphical representation of model shifts and belonging stresses are attached as well. Obtained stress values confirm that airplane undercarriage satisfies firmness condition with belonging safety factor. Conclusion based on obtained results is given at the end.
