At present, the lumped-parametric model is often used in the preliminary design of bladed
disks. However, the lack of systematic modeling methods leads to high errors. In order to …

Modern turbomachinery blades have extremely low inherent damping, which can lead to
high transient vibrations and failure through high-cycle fatigue. Smart materials enable …

Manufacturing tolerances and engine wear produce slight variations in the nominally
identical blades of a bladed disk, or blisk. In theory, the vibrational energy of a tuned blisk is …

In this paper, a synchronous vibration control method was proposed to avoid the high-cycle
fatigue fracture of aeroengine rotor blade. Firstly. The harmonic force, causing synchronous …

This paper presents an assumed mode approach for modeling academic blisk geometries.
This model decomposes the kinetic and potential energies using shape functions derived …

The high-fidelity finite element model (HFFEM) and Monte Carlo (MC) simulation of the blisk
involve large number of calculations, which leads to low computational efficiency. In this …

T blades experience periodic forcing from rotor-stator airflow interaction and rotation effects.
This periodic forcing causes blade vibration which, over time, can lead to high-cycle fatigue …

As advances in turbomachinery manufacturing have continued to improve, integrally bladed
rotors or blisks have become more prevalent due to the aerodynamic improvements that can …
