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, ...

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 ...

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 ...

Abstract: Abstract. The size of the finite element (FE) models used for turbomachinery applications is rapidly growing to consider the whole engine dynamics and the complex dynamic interactions between subassemblies, which are ...

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 ...

Abstract: Abstract. Friction damping devices like tip shrouds are usually employed in low pressure turbine (LPT) blades to reduce their large vibration amplitudes. From an engineering point of view, experimental validation of the ...
