power transmission/ A4340 Structural acoustics and vibration A4630M Vibrations, aeroelasticity, hydroelasticity, mechanical waves, and shocksThe present letter is devoted to the low frequency pattern of acoustic radiation generated by the vibration of a circular elastic plate in unbounded space. The ...
Undesirable vibrations are controlled in a mechanical structure by confining the vibrations to one or more specified areas of the structure and then dissipating the confined energy by damping. Vibration confinement is achieved using a co... D Allaei - US 被引量: 61发表: 0年 Control of bridges...
has now discovered that ‘synchronic’ fluctuations of the objects’ surfaces, caused by random vibrations of surface atoms, give rise to friction. Such vibrations exist at any non-zero temperature and their intensity decrease with decreasing temperature. This means that by ...
Energy-dissipation elastomers relying on their viscoelastic behavior of chain segments in the glass transition region can effectively suppress vibrations and noises in various fields, yet the operating frequency of those elastomers is difficult to control precisely and its range is narrow. Here, we repo...
It can be proved fromEq. (11.1)that under the condition of a given initial velocity and colliding distance, the deceleration process in whichHCIis minimized is a uniform deceleration process with constanta. In other words, to minimize the injury and damage caused by the collision, the resistance...
Vibration energy harvesters scavenge energy from mechanical vibrations to energise low power electronic devices. In this work, we report on vibration energy harvesting scheme based on the charging phenomenon occurring naturally between two bodies with di
In response to the vibration problem of helicopter fuselage caused by continuous rotor periodic excitation force, a nonlinear energy sink is considered to ... Z Dai,Z Feng,F Qian,... - IOP Publishing Ltd 被引量: 0发表: 2024年 Nonlinear energy sink vibration suppression and parameter optimizati...

The short response time of the collector is also relevant in situations of variable radiation (e.g., caused by frequent cloud passage). Sign in to download full-size image Figure 4.83. Plate temperature for a stalled, dry collector as a function of time. The incident flux is constant Ecsw...
1a), and thirdly the orientational fluctuations caused by bend-libration mixing (Fig. 1d), which all result in a decay of the excitation anisotropy. In isotopically diluted water, the contribution due to intermolecular bend-to-bend energy transfer is suppressed, because of the frequency mismatch ...
