Zaawansowane metody obliczeń naprężeń i odkształceń na przykładzie analizy korpusu silnika elektrycznego do kombajnu ścianowego KA200

Selected stages of realization of construction optimization process are presented in the article. In order to estimate displacements as well as strain and stress distribution the finite element method (FEM) is commonly used and the calculations were carried out using this method. To optimize the construction the computer system Autodesk Inventor Simulation 2009 was used. Strength analysis showed that the permissible stress limit in few details has been exceeded. To improve the tested construction the material of details were changed. To optimize the whole construction some other changes were also introduced.
