Experimental and FEM modelling for optimization of lightweight steel structures supported by fatigue tests of modern high strength structural steels

Popis výsledku v původním jazyce

Structural optimization has become very popular thanks to modern and powerful software tools. Nowadays a lot of various software for mechanical design and FEM analysis are available. Using those software tools some very nice lightweight structures can be design in fact, but in real practice there can be seen unexpected fatigue failures of those structures very often. This paper shows that optimization of modern lightweight structures using modern software tools can be done relatively easy but it also shows that optimization of lightweight structures which undergo cyclic loading should be in direct connection with fatigue testing of used materials. In this study, the optimization process of real lightweight structure (frame of the semitrailer) was supported by experimental determination of fatigue endurance, mechanical properties, microstructural and fractography analysis of used steels. Connection of structural optimization and detailed materials research resulted in successful and safety design of new lightweight frame of the semitrailer.
