nonstructural mass的阻尼问题

skipperyhf

这种单元对于阻尼是如何考虑的
比如集中质量单元
有damping这一项，但是nonstructural mass没有啊
用过么?

nonstructural mass的阻尼是和nonstructural mass所附着的单元的材料阻尼一致的。不过只有质量阻尼。

documentation中有：Any mass proportional damping specified as part of the material definition (see “Material damping,” Section 23.1.1) will also apply to the nonstructural mass contribution assigned to the element or element set using that material definition.
