Original abstract

The paper deals with issues of the virtual product development of the modern diesel engine. Cranktrain dynamics, acoustics and fatigue of main parts are fundamental problems that have to be considered in the engine development process. Modern software and hardware tools make it possible to increase powertrain parameters and decrease development time of powertrain. Finite element method (FEM) and multi-body system (MBS) are state of the art. The main components of the driving mechanism have been modelled as flexible bodies using FEM. Complete cranktrain dynamic model is assembled in MBS. Results from both FEM and MBS are used for fatigue calculations. Experimental verification of the computational model results has been performed by measuring the values on a testing engine unit using the non-contact laser measuring technique.
