RISEffect of Surface Roughness on the Point Contact EHL
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a full numerical solution for the partial elastohydrodynamic lubrication in elliptical contacts is presented, and the procedure of computation is briefly described. The average ...
Criteria for the Prevention of Split Ends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A criterion for the prevention of split ends (alligatoring) is expressed mathematically. This criteria, t0 /R0 >1.81×(t0 /tf −1) is derived through the extension of an earlier upper bound ...
Energetics and Stability of Translating Media with an Arbitrarily Varying Length
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear dynamics of a class of translating media with an arbitrarily varying length is investigated. The tension in the media arising from their longitudinal accelerations is incorporated. ...
Modeling of Fillets in Thin-Walled Beams Using Shell/Plate and Beam Finite Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fillets are commonly found in thin-walled beams. Ignoring the presence of a fillet in a finite element (FE) model of a thin-walled beam can significantly change the natural frequencies and ...
Theoretical and Experimental Investigation of Elevator Cable Dynamics and Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibratory energy of a moving cable in an elevator increases in general during upward movement. A control method is presented to dissipate the energy associated with the lateral vibration ...
Finite Element Modeling of Structures With L-Shaped Beams and Bolted Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to bending-torsion coupled vibrations of the L-shaped beams and numerous uncertainties associated with the bolted joints, modeling structures with L-shaped beams and bolted joints is a ...
Dynamic Modeling and Optimal Control of Rotating Euler-Bernoulli Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear integro-differential equations, describing the transverse and rotational motions of a nonuniform Euler-Bernoulli beam with end mass attached to a rigid hub, are derived. The effects ...
Exact Response of a Translating String With Arbitrarily Varying Length Under General Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exact response of a translating string with constant tension and arbitrarily varying length is determined under general initial conditions and external excitation. The governing equation is ...
A Nonlinear Model of a Slack Cable With Bending Stiffness and Moving Ends With Application to Elevator Traveling and Compensation Cables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear, planar model of a slack cable with bending stiffness and arbitrarily moving ends is developed. The model uses the slope angle of the centroid line of the cable to describe the ...
Nonlinear and Time-Varying Dynamics of High-Dimensional Models of a Translating Beam With a Stationary Load Subsystem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear vibration and dynamic stability analyses of distributed structural systems have often been conducted for their low-dimensional spatially discretized models, and the results obtained from ...
