Especially in the complex industry environment, interference such as high humidity, high vibration, variable temperature, and multi-frequency noise always exists.
Studies conducted on such occupations should also, we believe, quantify body exposures to long duration activities, such as long working hours and exposure to whole body vibrations, variables which are certainly present in marines.
The time-averaged vibration power variables and kinetic energies of the system and the force transmissibility are formulated and obtained analytically and numerically.
Energy-based robust control strategy was proposed in [12] to improve the control performance of the traditional joint PD control by introducing additional control efforts through the evaluation of vibration related variables.
This paper aims at presenting a family of exact solutions for the longitudinal vibration of variable area rods.
Based on the classical plate theory, free and forced vibration of variable stiffness composite annular thin plates with elastically restrained edges is studied.
A differential quadrature (DQ) methodology recently developed by the authors is used to obtain a general and a computationally efficient and accurate DQ solution for free vibration of variable cross-section circular thin arches.
The free vibration of variable stiffness laminated composite rectangular plates is studied for the first time on the basis of three-dimensional elasticity theory combined with the p-version of the finite element method.
In this paper, the authors study periodic vibrations of variable stiffness composite laminates excited by a harmonic force.
The equations governing free, in-plane vibrations of variable curvature arches are derived and solved numerically to obtain frequencies and mode shapes for parabolic, sinusoidal and elliptic geometries.
