Mechanism of the Dynamic Response Amplification of Cable Transport Lines: Design Applications Based on Cable Tension Signal Analysis
Publisher: American Society of Civil Engineers
Abstract: Cables are used for engineering applications such as transport systems that involve mobile cables suspended between supports for carrying attached vehicles. Because of the inherent cable’s flexibility and the modification ...
Validation of Fault Rupture-Response Spectrum Analysis Method for Curved Bridges Crossing Strike-Slip Fault Rupture Zones
Publisher: American Society of Civil Engineers
Abstract: In response to the bridge damages observed in past earthquakes and the absence of practical analysis methods, a simplified analysis procedure named the fault rupture-response spectrum analysis (FR-RSA) method was developed ...
Efficient Targeted Energy Transfer With Parallel Nonlinear Energy Sinks: Theory and Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the targeted energy transfer (TET) phenomenon between a linear multi-DOF master structure and several slave parallel nonlinear energy sink (NES) devices during a 1:1 resonance ...
Targeted Energy Transfer From One Acoustical Mode to an Helmholtz Resonator With Nonlinear Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Targeted energy transfer from one acoustical mode to a Helmholtz resonator (HR) with nonlinear behaviors is studied. For the HR, nonlinear restoring forces and nonlinear damping are taken into account. A time multiple scale ...
Nonlinear Vibratory Energy Exchanges between a Two-Degree-of-Freedom Pendulum and a Nonlinear Absorber
Publisher: American Society of Civil Engineers
Abstract: The multi-time-scale responses of a two-degree-of-freedom pendulum coupled with a nonlinear absorber were studied. The absorber was positioned in an arbitrary direction with respect to those of the pendulum oscillations. ...
Reduced-Order Model for the Nonlinear Dynamics of Cables
Publisher: ASCE
Abstract: Formulation of governing equations for an elastic cable have a long and dated history. A unified framework to detect the dynamics of such systems is detailed, justified, and assessed numerically. Modal analyses are performed ...
