Torsion Vibration Analysis is an important task to evaluate a modern vehicle powertrain. A very useful software tool for dynamic run-up simulations offers ITI GmbH with its software SimulationX. Its 3D MBS features help to resolve actual questions, particularly tasks regarding mounting problems or structure-borne sound. For the analyzation of second engine orders in a common vehicle driving range the actual rigid body modelling is sufficient, but especially for calculation in a higher frequency range we see the necessity to built up also elastic body structures in our powertrain models. IAV simulation engineers think SimulationX would have a high potential to solve our tomorrow's problems, when it would be possible to include finite elements (FE) structures into existing simulation models in a same comfortable way like including 3D MBS features into 1D models. So IAV would be able to investigate the NVH behaviour (Noise Vibration Harshness) of a vehicle with SimulationX in the high frequency range of NOISE as well as in the low frequency range of VIBRATION.
