Originální abstrakt

The development process in internal combustion engine at the present time requires CAE models that deliver the results for the concept phase of the prototype. The combustion engine is a very complex problem consisting of many partial problems. The major problem is the interaction of the crankshaft and the crankcase. For more precise solution of this problem it is necessary to use complex 3-D models. Finite element method (FEM, ANSYS software used) and Multi-Body Systems (MBS, ADAMS software used) are suitable for calculation of these problems. The finite element model is converted from ANSYS into ADAMS. The finite element models are too complicated for MBS and require a reduction. For the reduction of FE models the Craig-Bampton method is used. The comparison of the calculation and the measurement is still a decisive quality criterion in the CAE environment. Non-contact measurements with laser Doppler vibration meters enable to verify the complex calculation models.
