Numerical Study of Forward and Backward Whirling of Drill-String
(The American Society of Mechanical Engineers (ASME), 2017)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 ... -
Interplay Between Dissipation and Modal Truncation in Ball-Beam Impact
(The American Society of Mechanical Engineers (ASME), 2017)We study a ball-beam impact in detail; and in particular, we study the interplay between dissipation and modal truncation. With Hertzian contact between a solid ball and an Euler–Bernoulli beam model, we find using detailed ... -
Global Behavior of a Vibro-Impact System With Multiple Nonsmooth Mechanical Factors
(The American Society of Mechanical Engineers (ASME), 2017)A nonlinear mechanical model of a vibro-impact system influenced by double nonsmooth mechanical factors that combine elastic and rigid impact is described. The theoretical solutions to judge the periodic motion stability ... -
Numerical Location of Painlevé Paradox-Associated Jam and Lift-Off in a Double-Pendulum Mechanism

A Comprehensive Set of Impact Data for Common Aerospace Metals
(The American Society of Mechanical Engineers (ASME), 2017)The results of two sets of impact experiments are reported within. To assist with model development using the impact data reported, the materials are mechanically characterized using a series of standard experiments. The ... -
Soft Impact in a Biomechanical System With Shape Memory Element
(The American Society of Mechanical Engineers (ASME), 2017)The analysis of the shape memory prosthesis (SMP) of the middle ear is presented in this paper. The shape memory prosthesis permits the adjustment of its length to individual patient needs, but sometimes the prosthesis ... -
Interaction Between Coexisting Orbits in Impact Oscillators
(The American Society of Mechanical Engineers (ASME), 2017)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
(The American Society of Mechanical Engineers (ASME), 2017)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 ... -
