Effect of vibration exposure duration on discomfort [PDF]
, 2008 The comfort of a seated person exposed to vibration is known to depend on the magnitude, frequency content, and direction of the excitation. A review of the literature showed that very little is known about the effects of the duration of exposure to ...

A Generalized Approach to Coupled Nonlinear Vibrations of Continuous Systems [PDF]
Mathematical and Computational Applications, 1997 A mathematical model covering many practical vibration problems of continuous systems has been proposed. The equations of motion consist of two nonlinearly coupled partial differential equations. The quadratic and cubic nonlinearities as well as the linear part of the equations are represented by arbitrary operators.

Journal of Marine Science and Engineering, 2023 In this paper, an analytical dynamic model is proposed for vibration suppression of a multi-span continuous bridge by tuned mass dampers (TMDs). Firstly, the partial differential equations (PDEs) that govern the motion of the multi-span continuous bridge

Mechanism of nonlinear biodynamic response of the human body exposed to whole-body vibration [PDF]
, 2008 When the human body is exposed to mechanical vibration, the resonance frequencies of the frequency response functions, such as apparent mass and transmissibility, decrease with increasing magnitude of excitation. For the past two decades, this biodynamic

Reduction of Vibrations in Long-Span Continuous Girder Bridges with Pounding Tuned Mass Dampers
Advances in Civil Engineering, 2022 Earthquakes often cause bridges to vibrate to different degrees; moreover, in the case of poor road conditions, the vibration amplitude of bridges caused by vehicles often exceeds a reasonable range, thus causing different degrees of damage to bridges ...
