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 this study, a novel design for ring dampers is proposed, where the concept of tuned
vibration absorbers is leveraged to substantially increase damper effectiveness while …

Dynamic vibration absorbers array (DVAA) is a newly developed and promising technique
for vibration attenuation of integrally bladed disk (blisk) by mounting underneath the disk. In …

Turbomachinery blisks have very low damping and, for this reason, they require devices
such as ring dampers to mitigate excessive vibrations. Ring dampers rely on the relative …

The study of blisks is essential to the development of safe and efficient turbomachines.
Blisks are geometrically complex structures exposed to high temperatures and pressures …

Dynamic vibration absorber array (DVAA) is a promising technique for vibration mitigation of
integral blisk. In this paper, the effectiveness of the DVAA method is experimentally validated …

Due to the demand for lighter aircraft and increased engine efficiency, bladed disks
manufactured as a single component (ie, blisks) have seen increased interest for use in …

Blisk is a crucial component of high-performance aircraft engines. The increasingly
pronounced vibration issues of blisks have become a significant bottleneck in developing …
