摘要
针对储氢材料深冷温区冲击试验技术瓶颈,介绍了国内外深冷温区冲击试验方法研究现状,重点通过制冷技术发展现状、温区系统的控制、冲击测试技术3个方面阐述了深冷温区冲击试验方法研究进展.说明了通过采用试样的绝热保温进而控制试样的回温特性对试验过程进行过冷温度补偿的方式,能够有效解决深冷环境低温冲击试验的准确度问题.最后,分析了制约该项技术发展的瓶颈和研究相对缓慢的原因,为深冷环境冲击试验的标准制定和下一步研究工作提供参考.
Abstract
In view of the technical bottleneck of impact test in deep cold temperature zone for hydrogen storage materials,the research status of impact test methods in deep cold temperature zone at home and abroad was introduced.The research progress for impact test methods in deep cold temperature zone were described through the following three aspects:the de-velopment status of refrigeration technology,the control of temperature zone system,and the impact test technology.It showed that the control of return temperature characteristics of sample by insulation to compensate for the subcooling tem-perature in the experimental process could effectively solve the accuracy issue in low-temperature impact test in deep cold environments.Finally,the bottlenecks of restricting the development of this technology and the reasons for relatively slow development were analyzed.This study provided references for the standard establishment of impact test in the deep cold environment and the following work in future.
