摘要:
以含相变的多层板热传递理论为依据,采用有限单元法对金属蜂窝夹芯板进行了热分析,研究其在高温栽荷作用下的相变问题,计算结果表明,蜂窝夹芯板具有良好的隔热性能,内外表面间最大温差超过450℃；蜂窝芯温度场分布与其余四层不完全相同；各层板受内部设备的影响不同；外蒙皮在加栽18 s后开始产生固液相变,外胶层11s后开始产生固液相变,到14 s时已产生大面积气液相变,损伤面积和损伤程度不断增加,有限单元法较好地模拟了复杂结构在高温载荷作用下的温度场分布、相变失效过程及其演化规律.
Abstract:
Based on heat transfer theory with phase change of multilayer board，thermal analysis was imple-mented for metal honeycomb sandwich plate with finite element method ( FEM).The research of phase changeproblem undexr high temperafure load was carried out.The computing results show that honeycomb sandwichplate has good heat insulation performance， the maximum tcmperature difference was more than 450 ℃ bc-tween the inside and outside surface;temperature field distribution in the honeyeomb core layer is not com-pletely identical to the other four layers ; it is different that each layer is influenced by the internal devices ; theouter skin begins to form the solid-liquid phase change after loaded 18s，the outer glue starts to produce solidliquid phase change aiter loaded 11s , and has already large area of gas-liquid phase transition to 14s , damagearea and damage degree are increased continuously. It has been better simulated with FEM that temperatureficld distribution laws，phasc transition failure process and its cvolution of thc complcx strucetures under hightemperature load.
