摘要 针对四种不同阻尼形式的主结构-动力吸振器模型,即(a)主结构滞回阻尼,吸振器滞回阻尼;(b)主结构滞回阻尼,吸振器粘滞阻尼;(c)主结构粘滞阻尼,吸振器滞回阻尼;(d)主结构粘滞阻尼,吸振器粘滞阻尼,详细推导了动力放大系数的表达式,然后采用范数优化准则得到了各个模型的最优参数。在最优参数下,比较不同阻尼形式的吸振器对于同样形式阻尼的主结构吸振性能的差异,以及这些差异在不同质量比和不同的主结构阻尼因子下的变化趋势。分析结果表明,滞回阻尼吸振器和粘滞阻尼吸振器在质量比较小或主结构阻尼因子较小的情况下差别较小,但对于共振区的抑振效果,两者还是存在一定的区别。 Dynamic amplification factors of four types of primary structure (PS) - dynamic absorber (DA) models, i.e. (a) hysteretic damping in PS -hysteretic damping in DA; (b) hysteretic damping in PS -viscous damping in DA; (c) viscous damping in PS -hysteretic damping in DA; (d) viscous damping in PS -viscous damping in DA, are given and the optimal parameters are derived by norm optimization. Given the optimal parameters, vibration absorbing performance of different absorbers and its variation to mass ratio and damping ratio of PS are compared. Analysis results have shown that there is small difference in performance for hysteretic damper and viscous damper when the mass ratio and damping ratio of PS are small, but there exits some difference in resonance suppression effectiveness.
