This paper documents the result of twist fatigue life simulation correlated with test for an automotive rear suspension. The simulations were performed on both accelerated and standard twist test under constant amplitude cyclic loading. The accelerated twist test was developed for correlation. The result shows that the analytical fatigue life correlates with the test fatigue life within a factor of 2. However, the experiment shows that a crack appears exactly at the v−reinforcement tips to the weld toes as simulation predicted. It is observed that the welds are an important factor in this simulation and rigid modeling is feasible. This project also serves as a case study to the students in predicting fatigue failure of a real industrial part.
