RISExperimental Study on Impeller Blade Vibration During Resonance—Part I: Blade Vibration Due to Inlet Flow Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Forming the first part of a two-part paper, the experimental approach to acquire resonant vibration data is presented here. Part II deals with the estimation of damping. During the design ...
Experimental Study on Impeller Blade Vibration During Resonance—Part II: Blade Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Forming the second part of a two-part paper, the estimation of damping is presented here. Part I discusses the experimental approach and the results on blade resonant response measurements. In ...
The Cumulative Effects of Forcing Function, Damping, and Mistuning on Blade Forced Response in a High Speed Centrifugal Compressor With Inlet Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibratory response amplitude of a blade under forced response conditions depends primarily on the aerodynamic excitation amplitude, on damping, and on the effects of mistuning. The work ...
Blade Forcing Function and Aerodynamic Work Measurements in a High Speed Centrifugal Compressor With Inlet Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Centrifugal compressors operating at varying rotational speeds, such as in helicopters or turbochargers, can experience forced response failure modes. The response of the compressors can be triggered ...
Unsteady Computational Fluid Dynamics Investigation on Inlet Distortion in a Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blade failure in turbomachinery is frequently caused by an excessive resonant response. Forced response of the blades originates from unsteady fluid structure interactions as conditioned in the ...
