One of the common failure modes of the diesel-engine turbochargers is high-cycle fatigue of the turbine-wheel blades. Mistuning of the blades due to the casting process is believed to contribute to this failure mode. The turbine-wheel designs under investigation is radial and is typically used in 6-12L diesel engine applications. A continuous twistedblade model is developed in Matlab using finite-element techniques. The model is tested and validated against different symmetrical cases as well as ABAQUS results. It is proposed to use this model for statistical mistuning studies of turbine wheels in the product design stages.
