Original abstract
The internal combustion engine development process requires CAE models which deliver results for the concept phase at very early stage and which can be further detailed on the same program platform as the development process progresses. The vibratory and acoustic behaviour of the powertrain is a highly complex one, consisting of many components that are subject to loads that vary greatly in magnitude and which operate at a wide range of speeds. The interaction of the crankshaft and engine block is a major problem for the powertrain designer when optimising the vibration and noise characteristics of the powertrain. Finite Element Method (FEM) and Multi-Body Systems (MBS) are suitable for creation of 3-D calculation models. Non-contact measurements with laser vibration meters enable to verify the calculation models.
Czech abstract
Vývoj nových pohonných jednotek vyžaduje aplikaci CAE modelů již v prvních etapách projektu. Návrh hnacího ústrojí spalovacího motoru je komplexní problém, především řešení interakce klikového mechanismu a bloku motoru. Příspěvek se zabývá možnostmi aplikace programů MKP a multi-body systémů pro řešení této úlohy. Verifikace výpočtových modelů je realizována bezkontaktním měřením laserovými vibrometry.
