The Hamel Representation: A Diagonalized Poincaré Form
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Poincaré equations, also known as Lagrange’s equations in quasicoordinates, are revisited with special attention focused on a diagonal form. The diagonal form stems from a special choice ...
Forced Nonlinear Oscillations of a Semi-Infinite Beam Resting on a Unilateral Elastic Soil: Analytical and Numerical Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamics of a semi-infinite Euler–Bernoulli beam on unilateral elastic springs is investigated. The mechanical model is governed by a moving-boundary hyperbolic problem, which cannot be solved ...
Mechanism Dynamics Sequence-Solution Method and Its Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to eliminate the interference of reverse-driving and the positive or negative value of normal pressure on the direction of frictional force, in solving mechanism dynamics equations, a ...
Interaction Between Coexisting Orbits in Impact Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impact oscillators exhibit an abrupt onset of chaos close to grazing due to the square-root singularity in their discrete time maps. In practical applications, this large-amplitude chaotic vibration needs to be avoided. ...
A Preliminary Experimental Study About Two-Sided Impacting SDOF Oscillator Under Harmonic Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shaking table tests have been carried out to investigate the pounding phenomenon between a mass and two-sided shock absorbers, subject to sinusoidal excitations. In an effort to investigate the effectiveness of such an ...

Directions of the Tangential Creep Forces in Railroad Vehicle Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In some of the wheel/rail creep theories used in railroad vehicle simulations, the direction of the tangential creep forces is assumed to be the wheel rolling direction (RD). When the Hertz ...
Numerical Study of Forward and Backward Whirling of Drill-String
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a numerical investigation of the undesired lateral vibrations (whirling) occurring in drill-strings, which is one of the main sources of losses in drilling applications. The numerical studies are conducted ...
Efficient Simulation of a Dynamic System with LuGre Friction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Friction is a difficult phenomenon to model and simulate. One promising friction model is the LuGre model, which captures key frictional behavior from experiments and from other friction models. ...
Sources of Error in a Simulation of Rigid Parts on a Vibrating Rigid Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a simulation study of an important rigid-body contact problem. The system in question is composed of a rigid plate and a single rigid body (or particle). The plate follows a ...
