摘要
文章选用MATLAB作为系统的开发平台,编制了1套分离式Hopkinson压杆(SHPB)实验的数据处理软件。软件可以快速、高精度完成冲击压缩和动态劈裂实验的数据处理过程。软件采用交互式界面进行数据和参数的输入输出,实现入射波、反射波和透射波及数据处理过程的可视化。通过本软件最终可获得冲击压缩试验和动态劈裂试验的多种有效数据及曲线。包括冲击压缩试验中用三波法和两波法得到的应力——应变曲线和应变率、应变、应力、实验过程中各种能量时程曲线。动态巴西试验中试样拉应力、各种能量时程曲线和劈裂强度等。
In this paper, the data processing software for a set of separate Hopkinson pressure bar （SHPB） tests is developed by using MATLAB as the developed platform of this system. The software can accomplish the data processing of the shock compression and dynamic split tests quickly and with high precision. The data and parameters of the system are input and output by using the interactive interface, and the visualization of the process of the incident wave, reflected wave and transmission wave is realized. A variety of effective data and curves of impact compression test and dynamic splitting test could be obtained through this software. Including the stress--strain curves obtained by the three wave method and the two wave method in the shock compression test, and the time history curves of strain rate, strain, stress and various energy during the tests process. Morever the time history curves of various energy, tensile stress and splitting strength in dynamic Brazilian tests.
