Advanced Numerical Simulation Techniques for Fatigue and NVH Optimization of Motor Sport Engines

Linear static and dynamic analysis are state-of-the-art to determine the fatigue behaviour of crankshafts and the NVH behaviour of engines by use of the finite element method (FEM). Using direct methods for solving the equations even supercomputing does not help to prevent nonlinear transient analysis from being very time consuming and inefficient for the essentially large number of degrees of freedom.

Presenting analysis results of a W12 motor sport engine, nonlinear simulation techniques are shown to be both highly sophisticated and efficient for determining the fatigue and the NVH behaviour of complete power units.
