摘要
为了便于在动力分析中计算粘弹性阻尼器的非线性反力 ,文献[1] 引用了一个描述粘弹性材料应力应变关系的公式 ,公式中有五个待定材料常数 ,目前一般的作法只是根据单一的工作频率确定这5个常数。本文导出了多种频率下工作的 5个材料常数的近似计算公式。和只考虑一种工作频率的情况相比 ,更加接近工程实际。
For describing nonlinear force of viscoelastic dampers in dynamical analysis,the formula describing relation between stress and strain of viscoelastic material has been founded in literature .There are five unknown constants in the formula.Commonly these five unknown constants are calculated by one working frequency.In this paper,we have analyzed the approximate formula calculating these five constants by multi-frequency.This method is more close to engineering practice.
