RISThe Two-Degree-of-Freedom Tuned-Mass Damper for Suppression of Single-Mode Vibration Under Random and Harmonic Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Whenever a tuned-mass damper is attached to a primary system, motion of the absorber body in more than one degree of freedom (DOF) relative to the primary system can be used to attenuate ...
Optimization of the Individual Stiffness and Damping Parameters in Multiple-Tuned-Mass-Damper Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of multiple tuned-mass-dampers (MTMDs) attached to a single-degree-of-freedom primary system have been examined by many researchers. Several papers have included some parameter ...
The Dynamics of Lead-Screw Drives: Low-Order Modeling and Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The closed-loop performance of a lead-screw drive is usually limited by a resonance in which the carriage oscillates in the direction of motion as the screw undergoes longitudinal and torsional ...
Aerodynamic-Rotordynamic Interaction in Axial Compression Systems—Part I: Modeling and Analysis of Fluid-Induced Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a first principles-based model of the fluid-induced forces acting on the rotor of an axial compressor. These forces are primarily associated with the presence of a nonuniform ...
Aerodynamic-Rotordynamic Interaction in Axial Compression Systems—Part II: Impact of Interaction on Overall System Stability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an integrated treatment of the dynamic coupling between the flow field (aerodynamics) and rotor structural vibration (rotordynamics) in axial compression systems. This work is ...
