TY - CONF A1 - Karger, Kai A1 - Bestle, Dieter T1 - Multi-Objective Blisk-Optimisation Taking into Account Environmental Influences T2 - 5th IC-SCCE International Conference: From Scientific Computing to Computational Engineering, Athen, 2012 N2 - A design change from bladed disk to blisk leads to stronger endurance limits. The paper deals with aerofoil adaption of a blisk within a multi-criterion optimisation loop. Blisks are more sensitive to external excitation since mechanical damping is very low. Thus stronger limits have to be applied which are hard to be fulfilled and hence it requires the use of numerical optimisation. Combination of 2D CFD and FEM in a common optimisation loop to re-design a given blisk. Determination of relevant features for improving blisk endurance. Modern process integration and multi-criterion optimisation tools in combination with today's increased computational power allow to perform mulitphysics design even in the case of complex industrial design tasks.
