摘要
运用AD INA有限元软件对高阻尼多层U形波纹管的轴向等效刚度进行了分析。考虑几何非线性、材料非线性、层间接触非线性以及夹层阻尼材料特性对波纹管轴向等效刚度的影响,其分析结果对含夹层阻尼波纹管的设计与研究有一定的参考意义。
The ADINA finite element software was used to analysis the high - damped multilayer U - shaped bellows' axial equivalent stiffness. Considering the geometric nonlinearity, material nonlinearity, nonlinear contact condition between layers, and interlayer damped material behavior impact on bellows' axial equivalent stiffness, a certain extent reference the analysis results for the significance. interlayer damped bellows' design and research have
