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］提出了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。本文分析了用曲线拟合的方法确定这五个常数的原理，导出了曲线拟合的相应公式，文中给出了算例。
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[1].There are five unknown constants in the formula.In this paper,we have analyzed the principle calculating the five constants by virtue of the curve fitting,founded corresponding formula.We have presented one calculated example.
