Nonproportional Intentionally Mistuned Turbine Blisk Design with Improved Component Modal Synthesis
An improved component modal synthesis-based nonproportional mistuning method (ICMS-NPMM) is proposed to investigate mistuned turbine Dish Brushes blisks (MTBs) since the high-fidelity finite element models (HFEMs) involve large number of computations, which leads to low calculation efficiency.To reduce degrees of freedom and suppress the flutter of
