Abstract

The increasing demands for improving the specific power output of modern power-trains and for reducing the component weight via lightweight design, require detailed expertise about the damage mechanisms occurring under real service loading conditions. Taking into account requirements for accelerated, cost-effective component testing and damage analysis, IABG developed a new test stand for thermo mechanical fatigue testing of cylinder heads. Thereby, both the test and development process of cylinder heads may be accelerated significantly. The implementation of an in-situ crack detection system enables the investigation of crack initiation and propagation as well as a 24 / 7 service of the test stand.
