Dynamics and Vibration Damping Behavior of Advanced Meso/Nanoparticle-Reinforced Composites

摘要

Nanoparticles and carbon nanotubes have wide potential applications and some of them are vibration damping and noise adsorbing composite materials. The focus in this paper is directed toward the development of the next generation of vibration damping composites, providing a manufacturing route and design concepts. The research work concentrates on an investigation related to nanoparticle-reinforced materials dynamic characterization and modelling of relationships between structure and mechanical properties of the materials across the length scales. The scope is to understand the damping mechanisms in the materials due to nanoparticles/tubes. In this paper the equilibrium equation of damping structure is described with FEM-based models and is solved with the help of a numerical code integrated in computer-based virtual-reality environment. Computational simulation and modelling tools could help to understand many physical effects and predict the behavior of materials and engineering components by computer-generated models.
