Cranktrain Dynamics Simulation - Central Module of Virtual Engine

dissertation

English

For crankshaft dynamic calculations, traditional methods based on simple calculation of torsional and bending vibration are state of the art but new calculation methods are necessary to achieve more accurate results that allow a design that is nearer to the mechanical limit. The combination of MBS and FEA methods is the most efficient way of calculating cranktrain dynamics. The results are boundary conditions for further investigations, not only for stress issues, but also for questions concerning friction and wearout of bearings or pistons. The new techniques will replace the traditional methods with the increasing power of modern computers. However, further studies are necessary to optimize the interaction of the CAE programs and to validate the new technology. This works deals with cranktrain dynamics.
