随着国内民航业的快速发展,机场场道的除雪化冰已成为急需解决的问题之一。基于相变储能材料和功能梯度设计思想,介绍了相变储能材料的性质和应用,将场道按功能要求设计成三层,在此基础上分析了动、静载荷作用下道面结构的强度。结果表明:1)静载荷作用下,道面结构整体应力偏大,相变储能材料管的应力最大;2)由于载荷移动速度很大,道面结构各层应力相对较小,但载荷作用处出现峰值;3)在动、静载荷作用下道面结构的总体位移较小,满足机场运行要求。
With the rapid development of the civil aviation industry in China, the snow removal and ice removal of the airport arena have become urgent problems to be solved. Based on the idea of phase change energy storage materials and function gradient design, the properties and applications of phase change energy storage materials are introduced. The field is designed into three layers according to the functional requirements. On the basis of this, the pavement structure under dynamic and static loads Strength of. The results show that: 1) Under the static load, the overall stress of the pavement structure is too large, and the stress of the phase change energy storage material pipe is the largest; 2) Because of the large load moving speed, the stress of each pavement structure is relatively small, 3) Under the action of static and dynamic load, the overall displacement of pavement structure is small, which meets the requirements of airport operation.
