Abstract:V magistrski nalogi je prikazan potek analize klešč ravnalnega stroja. Na obstoječi konstrukciji so se zaradi neprimerno oblikovanega konstrukcijskega detajla pojavile poškodbe. Cilj naloge je bil izboljšati konstrukcijo klešč na način, ki kar se da zniža verjetnost utrujenostnega zloma komponente. Opravljene so bile trdnostne analize modela, optimizacija topologije ter analiza življenjske dobe konstrukcije. Obstoječo konstrukcijo klešč ravnalnega stroja smo analizirali s programskimi paketi Simulia Abaqus CAE, Simulia fe-safe ter Caess ProTOp. Izračuni temeljijo na podlagi metode končnih elementov. S prilagoditvijo geometrijskih detajlov ter upoštevanjem rezultatov optimizacijskega orodja smo znižali koncentracije napetosti. To kaže tako primerjava napetostnih polj numeričnih analiz obstoječe in izboljšane konstrukcije, kot tudi primerjava življenjskih dob obeh modelov.

Title:Improvements in the construction of the stretching machine
Abstract:In the following master thesis, the process of numerical analysis of pliers as a part of straightening machine is made. On the existing construction certain damage has been induced, because of its inappropriately construction design. The aim of the work has been to ameliorate the construction of the pliers in a way that the possibility of fatigue fracture of the component would be as low as possible. Strength analysis of a model, topology optimization and life expectancy analysis of the construction have been done. An already existing pliers construction of the straightening machine has been simulated with help of Simulia Abaqus CAE, Simulia fe-safe and Caess ProTOp software packages. All calculations are based on the method of finite elements. By adjusting the geometrical details and by considering the results of optimization tool, we were able to lower the stress concentrations. That claim is proved both by comparing stress fields of old and ameliorated construction and by life expectancy comparison of both models.
Keywords:stretching machine, pliers, dimensioning, numerical simulation, fatigue
