扇形铅粘弹性阻尼器性能的有限元分析研究
|
摘要
设计了18组不同构造和参数的扇形铅粘弹性阻尼器(SLVD),采用ABAQUS软件对其进行有限元数值模拟分析,研究了铅芯个数、铅芯直径、铅芯布置形式、橡胶剪切模量、薄钢板与橡胶层厚度比及加载应变幅值对其耗能性能和阻尼特性的影响。分析结果表明:SLVD的耗能系数和等效阻尼比随着铅芯个数的增多、直径的增大而增大,随着橡胶剪切模量、应变幅值的增大而减小;铅芯布置形式应以双铅芯形式为宜,薄钢板和橡胶层的厚度之比应控制在0.4~0.5。
Eighteen different configured sector lead viscoelastic dampers(SLVD) were designed and analyzed through finite element software ABAQUS.The influence of configurations,such as the amount & diameter of lead cores,the arrangement form of lead cores,the shear modulus of rubber,the thickness ratio of thin steel & rubber layer and strain amplitudes of loading,on performance of energy dissipation and the damping characteristics was studied.The analysis results show that the energy dissipation coefficient and the equivalent damping ratio of SLVD increase with the growth of the amount & diameter of lead cores,but reduce with the increase of the shear modulus of rubber and the strain amplitudes of loading.The form of double lead cores is the best arrangement mode.The thickness ratio of thin steel & rubber layer should be controlled in the range of 0.4～0.5.
