Abstract:
V magistrskem delu je predstavljen postopek trdnostne analize ploščnega tipa toplotnega izmenjevalca. Da lahko izvedemo numerični preračun po metodi končnih elementov (MKE), je potrebno pridobiti 3D model toplotnega izmenjevalca. Model ploščnega tipa toplotnega izmenjevalca je bil pridobljen s pomočjo skeniranja oz. 3D računalniške tomografije. Na podlagi pridobljene geometrije s skeniranjem je bilo potrebno le-to ustrezno popraviti, da smo jo lahko nato uporabili za numerični preračun (numerični 3D model). Geometrija je bila parameterizirana, kar nam je omogočilo izvedbo parametričnih simulacij (spremljanje različnih odzivov glede na vhodno geometrijo). V numeričnem preračunu smo se ukvarjali z obremenitvenimi primeri prelotanih in neprelotanih mest v toplotnem izmenjevalcu ter posledično z različnimi napetostno deformacijskimi stanji in njihovim vplivom na pričakovano življenjsko dobo toplotnega izmenjevalca. Numerični preračuni (MKE) so bili izvedeni v programskem paketu Ansys Workbench, pri čemer smo pridobljene rezultate analizirali ter ustrezno karakterizirali odzive glede na predhodno določene obremenitvene primere.

Title:
Strength analysis of heat exchanger
Abstract:
The master's work presents the process of strength analysis of a plate-type heat exchanger. In order to carry out a numerical calculation using the finite element method (FEM), it is necessary to obtain a 3D model of the heat exchanger. The model of the plate-type heat exchanger was obtained by scanning or 3D computed tomography. Based on the obtained geometry by scanning, it was necessary to correct it accordingly, so that it could then be used for numerical calculation (numerical 3D model). The geometry was parameterized, which allowed us to perform parametric simulations (monitoring different responses depending on the input geometry). In the numerical calculation, we dealt with load cases of vented and non-vented places in the heat exchanger and, consequently, with different stress-deformation states and their influence on the expected lifetime of the heat exchanger. Numerical calculations (FEM) were carried out in the Ansys Workbench software package, whereby the obtained results heat exchanger, dimensioning, strength analysis, numerical simulation, FEM,
