In principle, every vehicle is equipped by a suspension system, which usually consists of springs and shock absorbers. The main purpose the system to eliminate vibration sprung unsprung masses. Therefore, proper operation conditions absorbers affect in fundamental way total running properties vehicles. However, during operation, are being worn out or they can even be damaged. Then, such situati...

The Acoustic Black Hole (ABH) effect refers to a special vibration damping technique adapted thin-walled structures such as beams or plates. It usually consists of local decrease the structure thickness profile, associated thin viscoelastic coating placed in area minimum thickness. has been shown that structural design acts an efficient damper high frequency range, but not at low frequencies. T...

the application of energy absorbing systems in the structures are one of the main methods in attenuation of earthquake effects. in this paper, the vibration control of structures by using of tube inversion systems is considered. in this novel system, the energy is dissipated by the inversion of a metal tube. this energy dissipater has large energy absorbing capacity along with constant stiffnes...

All aircraft operate under vibration loads and these cause vibration-induced fatigue damage to the parts. Fatigue damages are dangerous because they occur suddenly without giving a warning before, for this reason need be carefully analyzed. In analysis, especially natural frequencies dampings must determined correctly, when match with frequencies, resonance is observed reduces life of part. stu...

in this work an improved method for designing a linear vibrational absorber, excited by random vibrations is presented and analyzed. first, analytical expressions, for non-stationary white noise accelerations, are derived. the criterion is different from the conventional criteria, used for structural design under random vibration, and it is based on minimum displacement or acceleration response...

this study presents a new approach to control the nonlinear dynamics of an adaptive absorber using shape memory alloy (sma) element. shape memory alloys are classified as smart materials that can remember their original shape after deformation. stress and temperature-induced phase transformations are two typical behaviors of shape memory alloys. changing the stiffness associated with phase tran...
