Hydrodynamic Impact-Induced Vibration Characteristics of a Uniform Euler-Bernoulli Beam, subject to typical impact loads and time scales. Assuming small deflections of the Euler-Bernoulli beam, normal mode summation is used to calculate the dynamic deflections in space and time. The modal governing differential equation is non-dimensionalized in space and time, and the dynamic load fac

Random Vibrations with Inelastic Impacts,oblem due to discontinuities in the state space paths of displacement and velocity response. It is shown that by introducing a suitable transformation of the state space variables, PI can be much simplified, and very accurate numerical results can be obtained. This is verified by comparison with ext

Performance of a Bi-unit Damper Using Digital Image Processing,ution of this work is to experimentally analyze the performance of a bi-unit impact vibration absorber using digital image processing. With the use of this technique, two or three bodies will be tracked simultaneously, namely, the primary system, and either the response of one or two impacting steel

Periodic Motion Stability of a Dual-Disk Rotor System with Rub-Impact at Fixed Limiter,amical model of the system is proposed with ordinary differential equations with two dimensional freedoms of transverse vibrations of the two rigid disks along the shaft. With the first order approximation of the piece-wisely rub-impact force, the solutions of periodic motions are deduced with harmo

A Theory of Cavitation Erosion in Metals Based on the Concept of Impact Fatigue,ollapse of bubbles at or near the metal surface, is of two kinds: (a) surface craters, and (b) surface pits involving cracking..(ii) After an incubation period, the erosion rate increases, goes through a maximum and them settles down to a constant value..(iii) As the erosion rate increases, the surf

,Sloshing-Slamming Dynamics – ,, – Analogy for Tuned Liquid Dampers,h installations in structures range from skyscrapers, chimneys, masts, airport control towers, bridges and offshore structures. Unlike other passive inertial systems such as tuned mass dampers (TMDs), which are linear by design, TLDs are inherently non-linear. The non-linear behavior of TLDs is char
