RISA Test Rig for the Experimental Investigation on the Nonlinear Dynamics in the Presence of Large Contact Interfaces and Numerical Models Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The simulation of the coupling between components modeled by finite elements (FEs) plays an important role for the prediction of the forced response of the assembly in terms of resonant frequencies, vibration amplitudes, ...
A Reduction Technique for the Calculation of the Forced Response of Bladed Disks in the Presence of Contact Mistuning at Blade Root Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of differences in nominally equal sectors of a bladed disk (mistuning) is a well-known problem for designers since the forced response may show localized amplification of the blade response with respect to a ...
Hybrid Numerical-Experimental Model Update Based on Correlation Approach for Turbine Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bladed-disks in turbomachines experience high cycle fatigue failures due to high vibration amplitudes. Therefore, it is important to accurately predict their dynamic characteristics including the mechanical joints at ...
Inverse Design of Compressor/Fan Blade Profiles Based on Conditional Invertible Neural Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compressors/fans are crucial in modern aircraft engines, providing power, thrust, and combustion efficiency. Blade profile design is a crucial aspect of the overall process, often involving multiple constraints. Current ...
