请问 关于内阻尼
关于阻尼有很多概念，比较头疼。现在做数值仿真时，想用到一个转子的内阻尼（也许有人叫做结构阻尼？也即和位移有关的阻尼？），已知该转子的材料和尺寸，请问如何能查到或者估算下大概的内阻尼系数？
注：本仿真只考虑内阻尼，外阻尼忽略不计。
多谢各位高手！ 现摘录一段话（引自chopra的结构动力学）：
Experiments on structural metals indicate that the energy dissipated internally in cyclic straining of material is essentially independent of the cyclic frequency,Similarly,forced vibration tests on structures indicate that the equivalent viscous damping ratio is roughly the same for all natural modes and frequencies.Thus we refer to this type of damping as rate-independent linear damping.Other terms used for this mechanism of internal damping are structural damping,solid damping,and hysteretic damping.We prefer not to use these terms because the first two are not especially meaningful and the third is ambiguous because hysteresis is a characteristic of all materials or structural systems that dissipate energy
我猜想结构阻尼在一些工具书上完全可以查到得。
建筑结构振动的结构阻尼的数值在一些书上就可以找到，例如王光远《建筑结构的振动》P16
个人意见，仅供参考。 谢谢。基本原理是了解的。 对于该阻尼系数，能否给出具体的参考？到底在哪里才能找到呢？
已经花了很多力气，没找到。 结构阻尼不是一个严格概念，理论上应该废掉，如果目前对付就按粘性阻尼加。 嗯。 可是的确想考虑内阻尼。真的这么难查找吗？
