Original abstract

The paper deals with the cranktrain development of a new diesel engine for possible military use. The engine utilized potentials are discussed at the beginning of the paper. The cranktrain vibration and fatigue are solved by computational approaches. The computational model incorporating flexible bodies is assembled and solved in Multi-Body System. Slide bearings are solved by a hydrodynamic approach. The results include vibrations of the cranktrain and also fatigue analyses of cranktrain key parts, such as crankshafts or a propeller shaft. There are also presented design modifications enabling reduction of vibrations and fatigue increase of main parts.

Prezentovaný příspěvek popisuje výpočtové metody vhodné pro řešení dynamiky leteckého motoru. Jsou zde představeny především modely pro řešení dynamiky a únavových problémů. Hydrodynamická část řešení je postavena na řešení Reynoldsovy hydrodynamické rovnice. Výsledky jsou prezentovány na vznětovém dvouválcovém motoru s protiběžnými písty.
