摘要
本文对一个结构阻尼力模型进行概括,将其表述为一个固体阻尼理论:频率相关粘性阻尼理论,并由此出发合理地建立了复阻尼理论;此外给出了它们和常用粘性阻尼理论的参数之间的关系式。文中提出了频率相关粘性阻尼振子在任意扰力作用下的响应分析方法,还研究了相应的多自由度系统问题,最后对有关的滞变阻尼问题进行了必要的讨论。
In this paper, a structural damping force model is generalized and represented as a solid damping theory——the frequency dependant viscous damping theory, and from this the complex damping theory is established rationally; in addition, the relationships among the parameters of them and the viscous damping theory commonly used are given. In the related studies, some methods of response analysis for an oscillator with a frequency dependant viscous damper are presented, which is subjected to an arbitrary disturbing force, and also the solution of the corresponding problem of multidegree of freedom is introduced. Finally, the necessary discussion of a problem about a hysteretic damping theory is made.
