An improved component modal synthesis-based nonproportional mistuning method (ICMS-NPMM) is proposed to investigate mistuned turbine 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 MTB. it is divided into mistuned blade structure... https://smokeaers.shop/product-category/baggies/
