A system of computer simulation programs was developed for the calculation of transient EHD analyses of connecting rods. Two different models for the calculation of the elastic deformations are compared: full dynamic deformations and quasi static deformations. For the quasi static analyses fixed displacement boundary conditions have to be applied, whereas for the full dynamic simulation no displacement boundary conditions are necessary. The presented results show, that the choice of boundary conditions and distributed mass effects strongly influence global and local deformations and lead to the conclusion, that the full dynamic solution should be used for connecting rod analyses.
