摘要(Abstract)：

30CrMnSiNi2A钢因其良好的塑性、韧性及抗冲击性能，已作为滑靴材料应用于高超声速火箭橇试验中。获得30CrMnSiNi2A钢宽温度域、宽应变速率范围内的本构模型是基于数值方法开展火箭橇刨削问题研究的必要条件。通过准静态压缩实验和动态冲击实验研究了30CrMnSiNi2A钢在25～800℃温度区间、0.0005～10000 s~(-1)应变速率范围内的静、动态力学性能，分析了应变速率和温度对30CrMnSiNi2A钢流动行为的影响，讨论了该材料的应变速率敏感性和温度敏感性，并进一步利用准静态压缩实验数据与动态冲击实验数据，建立了能够考虑应变速率和温度效应的Johnson-Cook本构模型。结果表明：30CrMnSiNi2A钢的极限抗压强度并非单一地随应变速率的变化而变化，并且应变速率对极限抗压强度的影响不大；不管是承受准静态压缩还是动态冲击，30CrMnSiNi2A钢均表现出较强的热软化效应，温度敏感系数随着温度的升高而升高；Johnson-Cook本构模型能够有效预测出不同温度、不同应变速率条件下30CrMnSiNi2A钢的真实响应行为。
