A Modified Nonlinear Modal Synthesis Scheme for Mistuned Blisks with Synchronized Switch Damping
International Journal of Aerospace Engineering, 2018 In the authors’ previous work (MSSP 2017), we show that the synchronized switch damping based on negative capacitor (SSDNC) is a good candidate for vibration suppression of tuned blisks.

Mistuning Identification of Blisks at Higher Frequencies [PDF]
AIAA Journal, 2009 There is a large body of research on reduced-order modeling of bladed disks and integrally bladed disks (blisks) for predicting the mistuned vibration response. However, most work to date has focused on the lower frequency families of blade-dominated modes.

Vibration Analysis of a Pipeline System Based on Model Truncation
Shock and Vibration, Volume 2025, Issue 1, 2025.Designing a complex pipeline for a floating production storage and offloading (FPSO), particularly over long distances, presents significant challenges in vibration analysis. Traditional modeling methods, which often assume finite lengths and simple configurations, fall short as they do not account for the integrality and locality of long spans and the
