Turbine bladed disks or blisks, which constitute critical components of most modern
turbomachinery, are known for their complex vibratory behavior. The nonlinear dynamics …

A new reduced order modeling technique for nonlinear vibration analysis of mistuned
bladed disks with shrouds is presented. The developed reduction technique employs two …

This paper introduces a new type of damper for turbomachinery blisks. The major pitfalls of
the damper concepts currently employed are two: the low level of relative motion that is …

In general, only in tangential direction, friction motion between blade dampers is concerned
for vibration analysis of mistuned bladed disk. However, in practical, excitation acting on …

A new reduced order modeling technique for nonlinear vibration analysis of mistuned
bladed disks with shrouds is presented. It has been shown in the literature that the loss of …

The vibration absorber or tuned mass damper is a well-known mechanism, where a small
mass connected to a larger structure is used to redirect vibration energy and provide …

Modern turbomachinery contains integrally bladed disks, or blisks, which are nominally
cyclic symmetric structures manufactured as a single piece. Unlike traditional disks with …

In this work, the impact of small mistuning on rotor/stator contact interactions is investigated.
First, a detailed study of a rotor/stator interaction between the first bending modes and the …

This paper deals with the real dynamics characteristics of a mistuned steam turbine bladed
disk subjected to dry friction forces to better understand the nonlinear mistuning …

Shrouded bladed disks exhibit a nonlinear dynamic behavior due to the contact interfaces at
shrouds between neighboring blades. As a result, reduced order models (ROMs) are …
