Natural Frequencies and Modes of Inclined Cables
Publisher: American Society of Civil Engineers
Abstract: Asymptotic equations are derived for the natural frequencies and mode shapes of an elastic, taut, inclined cable. The equations are derived from more general asymptotic results by assuming quasi‐static stretching. It is ...
Riser Response Analysis by Modal Phase Reconstruction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A methodology is presented to identify the vortex-induced vibrational modes of a riser, based on data from computational fluid dynamics coupled to a long beam under tension and placed in cross ...
The Nonlinear Dynamics of Long, Slender Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear dynamics of long, slender cylinders for moderately large deformations are studied by projecting the solution along the set of eigenmodes of the linear problem. The resulting set ...
Shock Waves in Curved Synthetic Cables
Publisher: American Society of Civil Engineers
Abstract: The formation, propagation, and reflection of shock waves is studied for synthetic curved cables. First, analytical solutions are derived for weightless cables with nonlinear stress-strain relation, which are then compared ...
Force and Power Estimation in Fish-Like Locomotion Using a Vortex-Lattice Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The forces and power needed for propelling at constant speed an actively swimming flexible fish-like body are calculated. A vortex-lattice method based on a linearized theory is employed and ...
Drag Forces and Flow-Induced Vibrations of a Long Vertical Tow Cable—Part II: Unsteady Towing Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Full-scale experimental data on the dynamics and flow-induced vibrations of a long vertical tow cable are analyzed. The data were measured while the surface ship was going through a series of ...
Drag Forces and Flow-Induced Vibrations of a Long Vertical Tow Cable—Part I: Steady-State Towing Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analysis of data from a unique experiment on the quasistatics and vortex-induced dynamics of a long vertical tow cable is presented. The experiment consisted of measuring simultaneously the ...
Review of Hydrodynamic Scaling Laws in Aquatic Locomotion and Fishlike Swimming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We consider observations and data from live fish and cetaceans, as well as data from engineered flapping foils and fishlike robots, and compare them against fluid mechanics based scaling laws. ...
