多翼型粘弹性阻尼层叶片的动态特性数值分析
Numerical Analysis on the Dynamic Characteristics of Multi-wing Blade with Viscoelastic Damping Layers
摘要
Abstract
We adopted ANSYS to build single-wing and multi-wing blade models with composite materials for 2MW wind machine .Viscoelastic damping layer was added into multi-wing blade to make a harmonic response analysis under rated wind speed and rated load . Difference of dynamic features was explored .And effects of the number of viscoelastic damping layers and the thickness were investigated on the dynamic features of multi-wing blade .Results of the research have shown that ,with a higher frequency , displacement and strain energy of the multi-wing blade are smaller than those of single-wing blade ;viscoelastic damping layer can restrain the displacement and strain energy of multi-wing blade with a lower frequency .关键词
