褶皱结构是二十世纪九十年代中期最先在国外出现的一种纵向和横向均呈之字形曲折的异形芯材结构,这种结构是一种新的、具有广泛应用前景的飞机结构材料。它的特点是具有较高的抗弯刚度质量比,较好的吸音、隔音、隔热和耐疲劳等性能。本文介绍了褶皱结构的基本热力学研究模型,根据褶皱结构的几何特征参数变化研究了各个参数对整个结构热传导系数的影响关系,用以满足不同的需要。
Fold structure is the first in the mid-nineties of the 20th century appeared in a variety of vertical and horizontal cross-shaped zigzag shaped core structure, this structure is a new, with a wide range of application prospects of aircraft structural materials. It is characterized by a higher bending stiffness than the quality ratio, good sound-absorbing, noise, heat insulation and fatigue resistance and other properties. In this paper, the fundamental thermodynamic model of the corrugated structure is introduced. According to the change of geometric characteristic parameters of the corrugated structure, the influence of each parameter on the thermal conductivity of the whole structure is studied to meet different needs.
