Abstract
It is essential for the numerical design of con rods to consider the interaction between structural deformation and hydrodynamics in the sliding bearings. Furthermore, the boundary conditions for the sub-system under consideration have considerable influence on the quality of the results. AVL List GmbH, as the developer of the software AVL EXCITE for the calculation of the non-linear dynamic behaviour of engines and power units, has extended the elasto-hydrodynamic bearing module by adding a mixed friction model. This leads to improved results, especially in the area of the small end bearing, and to a more realistic integration of the con rod into the simulation model of the entire system.
