摘要
分离式霍普金森杆(SHB)装置是材料高应变率动态力学性能试验中应用最广泛、适应性最强的试验装置。在本文中,对SHB测试装置的可行性进行了标准化。各种因素包括SHB分析设备的工作原理、应用范围、工作参数等方面。通过分析该装置的优点,可以了解到SHB装置标准化后使用该装置得到的材料的动态力学性能参数将成为通用的材料参数。同时,SHB装置技术的标准化可以促进采用此类标准装置的高应变率动态力学实验技术的统一,同时拓宽SHB装置应用要求范围。
The Separate Hopkinson Bar(SHB) device is the most widely used and adaptable test device in the high strain rate dynamic mechanical performance test of materials. In the paper, the feasibility of SHB test device is standardized. Various factors include the working principle, application scope, and working parameters of SHB analysis equipment. By analyzing the advantages of the device, it can be understood that after the SHB device is standardized, the dynamic mechanical performance parameters of the material obtained by using the device will become general material parameters. At the same time, the standardization of SHB device technology can promote the unification of high strain rate dynamic mechanics experimental technology using such standard devices, and at the same time broaden the scope of application requirements for SHB devices.
