|
摘要
为提高救生舱的隔热和安全性,设计一种泡沫铝填充结构救生舱。采用Workbench仿真分析的方法研究原型救生舱和泡沫铝填充结构救生舱的隔热和抗热-压力耦合冲击性能。通过对比分析可知在相同的热-压力耦合冲击作用下,泡沫铝填充结构救生舱的温度和应力及变形分别减小51.88%,30.19%和20.72%。证明:泡沫铝填充结构救生舱具有更好的隔热和安全性,为新型结构的救生舱设计与制造提供新思路和新途径。
In order to improve the thermal insulation and safety of the rescue cabin,a new type of rescue cabin filled with aluminum foam was designed. Through a workbench simulation analysis method,the heat insulation and resistance-pressure coupling property of both prototype rescue cabin and rescue cabin filled with aluminum foam were studied. By comparative analysis,the temperature,stress and deformation of the rescue cabin filled with aluminum foam were reduced by 51. 88%,30. 19%,and 20. 72%,respectively,under the same thermal and pressure impact. It proves that the rescue cabin filled with aluminum foam has better thermal insulation and safety. It thus provides a new idea and new way for the design and manufacture of rescue cabin.
