...Tong Jing; Chaoping Zang; Evgeny Petrov During accelerations and decelerations of gas-turbine engines, the transient vibration effects in bladed disk vibration become significant and the transient response needs to be efficiently and accurately assessed. This paper develops an effective method...

..., a first dedicated optimization strategy was defined and extensively validated on a single-degree-of-freedom-per-blade-disk model as well as on a reduced-order model of a blisk. This two-step approach is based on the solution of the optimization problem over a subspace in which two consecutive blades...

...Javier Avalos; Marc P. Mignolet The focus of this paper is on demonstrating the potential to damp entire bladed disks using dampers on only a fraction of the blades. This problem is first considered without the presence of random mistuning, and it is demonstrated that a few dampers at optimized...
