Linearization Technique for Probabilistic Riser Frequency Domain Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a rigorous derivation of equations for the minimization of the mean-squared error and defines the describing function for different input components. The technique has a ...
Experimental Evidence of Quasiperiodicity and Its Breakdown in the Column-Pendulum Oscillator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new vibration absorbing device is introduced for large flexible structures. The phase-space of the experimental system is reconstructed via delay-coordinate embedding technique. Experimental ...
Pendulum as Vibration Absorber for Flexible Structures: Experiments and Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic response of a beam-tip mass-pendulum system subjected to a sinusoidal excitation is investigated. A simple pendulum mounted to a tip mass of a beam is used as a vibration absorber. ...
Response of Two-Degree-of-Freedom Rotating Machinery System With Quadratic Nonlinearity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-degree-of-freedom model of a rotating machine with nonlinear springs of quadratic type is studied. The multiple scales method is used to investigate the nonlinear oscillations of the forced ...
Stochastic Response of Tension Leg Platform to Wave and Current Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear analysis in the frequency domain is presented for the surge motion of a tension leg platform (TLP) in the case of random waves only and random waves with constant current. A ...
Fatigue Loads on the Foundation due to Turbine Rotor Eccentricity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with the effect of rotor eccentricity on the turbine behavior and the shaft deflection which affect the load on the foundation and on the turbine bearings. An analytical ...
Numerical Solution Techniques for Dynamic Analysis of Marine Riser
Publisher: The American Society of Mechanical Engineers (ASME)
A Review of Current Approaches to Riser Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to review the progress made during the past two decades towards the structural modeling and the numerical approaches of a more realistic riser analysis. Two or ...
A Comparison of Fracture Mechanics and S–N Curve Approaches in Designing Drill Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that the upper ball joint in a marine riser, in deep drilling, can cause fatigue damage in the drill pipe passing through it. A study of fracture mechanics and S–N curve ...
Feasibility Study of Ammonia-Water Vapor Absorption Heat Transformer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many industrial sectors reject heat to the atmosphere in the form of hot water with a temperature between 40° and 70°C. This low grade heat can be upgraded by using a vapor absorption ...
