摘要: 安全避难装置的热防护性主要取决于舱体的结构设计,通过设计带有隔热支撑的舱体结构来抵抗施加于舱体上的热冲击的影响。首先建立新型类三角形舱体结构模型;而后采用室内升温曲线,分别对舱体结构的外层、隔热层及内层进行瞬态热分析,分析舱体结构与火源存在一定距离及接近火源两种情况下的热传导性能,得到两种情况下舱体各层结构的温度变化云图及温度变化曲线;最后对瞬态热分析结果进行整理综合,结果表明:设计的舱体结构的隔热性能相对较好,满足危险条件下安全避难装置的热防护能力使用要求,为新型安全避难装置的设计及研究提供了理论指导。

Abstract: The thermal protection of the safety evacuation device is mainly dependent on the structural design of the cabin, and it can resists the effect of thermal shock applied to the cabin by designing cabin structure with insulation support. In this paper, a new model of the similar triangular cabin structure is established. The thermal protection performance of the similar triangular cabin structure is analyzed, and the indoor temperature rise curve is used to analyze the outer layer, the insulation layer and the inner layer respectively. The temperature of the reservoir layer changes in the cloud and the temperature curve of the cabin can be obtained by the analysis of the fire source having a certain distance and close to the fire. At the same time, the results of the two cases are summarized and the results show that the thermal insulation performance of the insulation structure designed in this paper is relatively good, and the thermal protection ability of the triangular cabin meets the requirements of the use of dangerous conditions, and provide theoretical guidance for the design and research of new safe evacuation devices.
Key words: safe evacuation device; the similar triangular cabin; thermal protection performance transient thermal analysis
