摘　　要：以选定的一种蜂窝夹层结构为例，对其低温力学性能即拉伸、压缩、剪切等进行了各种外界环境包括温度、粒子辐照、紫外辐照、冷热循环等影响前后的性能测试和研究。在大量试验的基础上，通过理论分析，找出了影响其低温力学性能的主要因素和变化规律，建立了用已知参数或常温参数推算蜂窝夹层结构低温力学性能的数学模型和计算公式。该模型的建立对于蜂窝夹层结构低温力学性能的设计具有较重要的指导意义。The mechanical properties of a kind of honeycomb sandwich structure under effects of low temperature,particle radiation,ultraviolet ray and hot cold cycles etc.,such as stretch,compress and shear,have been measured and researched.On the basis of a lot of experiment data,the main factors and regularity effecting the mechanical properties at low temperature have been found.The mathematic model and calculating formulas possessing general significance have been built and the mechanical properties of honeycomb sandwich structure at low temperature can be calculated by known parameters or room temperature parameters.The model and formulas are very important for guiding the design of the mechanical properties of honeycomb sandwich structure at low temperature.
