The safety of turbomachines requires controlling the risks caused by contacts occurring
between fixed and rotating parts. Undesirable phenomena induced by bladed wheel/casing …

Blade–casing interaction/rubbing can occur under the small blade-tip clearance, which may
lead to the rubbing damage, excessive wear of the abradable coating, and efficiency loss …

This paper focuses on the dynamic responses of whole aero-engine with blade-casing
rubbing. The vibration response of casing is simulated and the dynamic behaviors of casing …

This article presents a Harmonic Balance Method-based numerical strategy to provide a
qualitative numerical characterization of a compressor blade's dynamics when structural …

Considering the effects of blade rotation and casing flexibility, a new blade-casing rubbing
model is proposed. The blade is assumed to be clamped on a rigid disk and simulated by …

Higher aircraft energy efficiency may be achieved by minimizing the clearance between the
rotating blade tips and respective surrounding casing. A common technical solution consists …

Minimizing the operating clearance between rotating bladed-disks and stationary
surrounding casings is a primary concern in the design of modern turbomachines since it …

In order to improve the efficiency of aircraft engines, the reduction of clearances between
blade tips and their surrounding casing is one avenue manufacturers consider to lower …

In order to simulate the rubbing dynamics of the multi-blades/flexible casing, the finite
element model (FEM) of the blisk-oval casing system with elastic supports is established …

A cyclic sector corresponding to blade-disk structure with dovetail connection (1/38 blade-
disk) is studied and the finite element (FE) model of this structure is established based on …
