RISBlisk With Small Geometry Mistuning and Blend Repair: As-Measured Finite Element Model and Experimental Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an “As-Measured Model” (AMM) of a blended blisk, built upon the measurement of the true geometry of the blisk by the three-dimensional optical scanning technology. This high-fidelity model aims to account ...
Forced Response of Rotating Blisks: Prediction and Correlation to Blade Tip-Timing Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper explores two different blisk dynamic models for resonant vibration prediction of a rotating blisk test piece, i.e., the Model-BDTID and geometrically mistuned models (GMM). The former represents a mistuned blisk ...
Analysis of Nonlinear Modal Damping Due to Friction at Blade Roots in Mistuned Bladed Disks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method is proposed to analyze the modal damping in mistuned bladed-disk with root joints using large finite element models and the detailed description of frictional interactions at contact interfaces. The influence of ...
