Abstract: This paper addresses two main subjects. First, a novel test setup is described to experimentally study the nonlinear dynamic behavior of a turbine blade coupled with two midspan dampers (MSDs). To this end, a representative ...

Abstract: Friction dampers are one of the most common secondary structures utilized to alleviate excessive vibration amplitudes in turbomachinery applications. In this paper, the dynamic behavior of the turbine bladed disks coupled ...
