摘 要
采用霍普金森压杆试验研究了C72900铜合金与15-5PH不锈钢在不同应变速率下的动态力学性能；基于Johnson-Cook本构方程对应变-应力曲线进行拟合以确定材料参数，应用ABAQUS软件对压缩试验进行模拟以验证本构方程的准确性。结果表明：试验测得随着应变速率的增大，C72900铜合金和15-5PH不锈钢的流变应力显著增大，二者的流变应力行为相近；模拟得到C72900铜合金与15-5PH不锈钢在塑性变形阶段的真应力-真应变曲线与试验结果相吻合，相对误差小于3%，表明所建立的Johnson-Cook本构方程较好地描述了C72900铜合金和15-5PH不锈钢的流变应力特征；C72900铜合金替代15-5PH不锈钢应用于C919大飞机保险销垫片是可行并可靠的。

Abstract
Dynamic mechanical properties of C72900 copper alloy and 15-5PH stainless steel at different strain rates were studied by Hopkinson pressure bar test. The strain-stress curve was fitted on the basis of Johnson-Cook constitutive equation to determine material parameters. The compression test was simulated by ABAQUS software to verify the accuracy of the constitutive equation. The results show that the flow stresses of C72900 copper alloy and 15-5PH stainless steel increased significantly with increasing strain rate by tests, and both the materials had the similar flow stress behavior. The simulated true stress-true strain curves of C72900 copper alloy and 15-5PH stainless steel in the plastic deformation stage were consistent with the test results, and the relative errors were less than 3%, indicating that the established Johnson-Cook constitutive equations could describe the flow stress characteristics of C72900 copper alloy and 15-5PH stainless steel well. The application of C72900 copper alloy instead of 15-5PH stainless steel on the gasket of C919 aircraft safety pin was feasible and reliable.
