摘要
针对当前装备在极地使用过程中可能面临的极低温环境适应性问题,分析总结了南北两极温度、风、太阳辐射、盐雾等环境特征以及温度等环境因素变化规律,阐述了低温对金属、高分子材料强度、塑性、韧性等基本力学性能的影响及影响机理,概括总结了国内外极低温自然环境试验技术和实验室低温试验技术及标准发展现状,分析了现有极地低温试验方法存在的问题,并从多因素环境综合加速试验、低温-力学耦合试验、计算机仿真分析等三个方面对未来极低温环境适应性试验研究发展进行了展望.
Abstract
Aiming at the worthiness of equipment in extremely low temperature environment in the process of polar use at present,the environmental characteristics of the North and South Poles,such as temperature,wind,salt spray,solar radiation,and the change law of environmental factors such as temperature are analyzed and summarized.The effect and mechanism of low temperature on the basic mechanical properties of metals and polymer materials,such as strength,plasticity and toughness are expounded.The development status of ultra-low temperature natural environment test technology and laboratory low-tem-perature test technology and standards in China and abroad is summarized,the existing problems of the existing polar low tem-perature testing methods are analyzed,and the future research and development of extremely low temperature environment worthiness test is put forward from three aspects of multi-factor comprehensive acceleration test,low-temperature-mechanical coupling test and computer simulation analysis.
