How Intrusive Are Accelerometers for Measuring Nonlinear Vibrations? A Case Study on a Compressor Blade Subjected to Vibro-Impact Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A characteristic feature of nonlinear vibrations is the energy transfer among different parts or modes of a mechanical system. Moreover, nonlinear vibrations are often non-periodic, even at steady state. To analyze these ...
Effect of Modal Interactions on Friction-Damped Self-Excited Vibrations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well-known that nonlinear dry friction damping has the potential to bound the otherwise unboundedly growing vibrations of self-excited structures. An important technical example are the flutter-induced friction-damped ...
