把静态压缩本构方程拟合得到的应力-应变数据作为缓冲材料的载荷曲线，利用有限元仿真软件ANSYS LS-DYNA对DY-3重锤冲击EPP材料进行了仿真，得到了响应加速度-时间曲线，并与试验曲线进行了对比，误差在6%以内，说明了利用本构方程拟合的应力-应变载荷曲线，既能克服将缓冲材料简化为线性材料导致的缺陷，又避免了需要通过试验获取载荷曲线的弊端。

EPP drop test by DY-3 test machine was simulated by using ANSYS LS-DYNA and loading curves from stress-strain data fitted by compression constitutive equation. Response acceleration-time curves were obtained and compared with experimental result. Comparison results showed that the error of simulation result is less than 10%, which means that the fitting data derived by static compression constitutive equation can not only overcome the inaccuracy of simplifying EPP as a linear material, but also avoid using experiment to obtain the loading curve.
