THERMO-MECHANICAL FATIGUE OF SI-MO 4.06 TURBINE HOUSING OF TURBOCHARGER - DAMAGE OPERATOR BASED LIFETIME PREDICTIONS
Abstract eng: The paper presents application of damage operator based lifetime calculation for cast iron turbine housing of the turbocharger. Combination of thermo-mechanical fatigue and creep is considered, oxidation effect is taken into account indirectly. Results from transient thermal and elastoplastic finite element analysis are used for fatigue and creep damage calculation. Viscoplastic approximation based on nonlinear, strain controlled Maxwell model is used. Critical zones on the turbine housing of the turbocharger have been observed. Different damage parameters including dissipated energy for continuous damage calculation will be discussed.
