船舶内装板耐火分隔结构设计与性能研究

设计一种以气凝胶和铝蜂窝材料为主的船舶内装板结构。介绍了船舶內装板耐火分隔定义及设计方法。根据耐火分隔标准试验,设计以电加热板模拟加热炉温升的耐火分隔小尺寸样件模拟试验。根据小样模拟试验原理,建立耐火分隔有限元模型,结果表明,仿真和试验结果较为接近,仿真计算方法可以为耐火分隔结构优化提供手段。通过仿真分析计算,得到船舶内装板中气凝胶的最小厚度为5mm,內装板结构整体重量较50mm厚复合岩棉板轻25%。研究方法可以为新型耐火分隔结构的设计提供参考。

Fire-resistant insulation structure of shipboard interior panel design and its fire-resistance performance study

A kind of shipboard interior panel structure composed by aerogel was designed.fire-resistance insulation definition and its design method was introduced.based on standard testing of fire-resistance,subsize simulation testing was designed which an electrical heating panel simulating standard temperature rise curve was used.therefore,according to subsize testing Principle,fire-resistance FEA model was built.simulation and testing results show that the simulation method can generate highly precise results relative to testing results.thus the simulation method is a good way to Optimized design of fire-resistance structure.thickness of aerogel was calculated by simulation that is 5mm,and the weight of the panel lower 25% than 50mm composite rock-wool panel. Research method willSprovideSsome indicationSfor novel fire-resistance structure design.
