RISEquilibrium Solutions and Existence for Traveling, Arbitrarily Sagged Elastic Cables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exact, closed-form, three-dimensional solutions for the steady motion of traveling, sagged, elastic cables under arbitrarily distributed and concentrated loading are developed in this paper. ...
Nonlinear Stochastic Drill-String Vibrations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lateral vibrations of drill-strings used in oil well operations are considered. A finite elements based discretization procedure leads to a nonlinear dynamic system which is used to represent ...
Nonlinear Vibration of Rotating Thin Disks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response and natural frequencies for the linear and nonlinear vibrations of rotating disks are given analytically through the new plate theory proposed by Luo in 1999. The results for the ...
In-Plane Vibrations of a Thin Rotating Disk
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model for the in-plane oscillations of a thin rotating disk has been derived using a nonlinear strain measure to calculate the disk energy. This accounts for the stiffening of the disk due ...
Optimization of Proximity Recording Air Bearing Sliders in Magnetic Hard Disk Drives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The object of this paper will be to optimize the contact stiffness (CS) of an existing proximity recording air bearing surface (ABS). The CS is a measure of the slider’s increase in contact ...
Geometric Parameters Influencing Flow in an Axisymmetric IC Engine Inlet Port Assembly: Part I—Valve Flow Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Discharge characteristics in an IC engine inlet port and the dependency on geometrical parameters are examined for two valves having seat angles of 40 and 45 deg. The characteristics were ...
RANS Model for Spilling Breaking Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A RANS model for spilling breaking waves is developed, which can be implemented with ship hydrodynamics RANS CFD codes. The model is based on the Cointe & Tulin theory of steady breakers. ...
On the Anisotropy of Axisymmetric Strained Turbulence in the Dissipation Range
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Partition of the stress dissipation has been studied in an axisymmetric strained flow field to assess the possible existence of local isotropy for turbulence at small scales. This is a simple ...
A Simplified 4-DOF Suspension Model for Dynamic Load/Unload Simulation and Its Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mathematical models are critical for accurate simulation of the dynamic load/unload (L/UL) process in disk drives. The air bearing slider and the suspension are the most important parts in ...
Geometric Parameters Influencing Flow in an Axisymmetric IC Engine Inlet Port Assembly: Part II—Parametric Variation of Valve Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of inlet valve geometry on IC engine port flow characteristics was investigated systematically by varying the key valve geometric parameters of fillet radius, cone angle, and seat ...
