摘要: 通过实验数据和数值模拟结果的对比，研究了泰勒杆实验在材料动态本构关系参数确认和优化方面的应用。以Johnson-Cook模型描述的oxygen-free high-conductivity（OFHC） copper材料为例进行了具体说明，并对实验中的部分不确定因素进行了分析。结果表明，利用该方法对材料本构模型参数进行确认和优化确定是合理的。

Abstract: By comparing the results of Taylor test and computational simulation, a validating and optimizing method on dynamic constitutive model material constants was proposed. This method was applied to the Johnson-Cook model for OFHC copper and some uncertainty of Taylor test was analyzed. Results show that it is reasonable for validating and optimizing material constants for dynamic constitutive model with this method.
