Owing to continuous efforts by many researchers the cause of mistuned vibration of turbocharger radial turbine blades has been clarified as material inhomogeneity in addition to shape deviation. And also aerodynamic damping characteristics were evaluated by CFD analysis and the vibration test varying circumferential conditions. Further the aerodynamic excitation due to VG nozzle and turbine housing scroll was studied and some countermeasures are proposed respectively. This paper introduces digestibly such technical trend from recent papers presented on main international technical conferences.
