基于ANSYS的稻草/PS层合复合材料保温性能仿真分析

Simulation Analysis of Polystyrene Cystosepiment and Straw Board Lamination Compound Materials Heat Preservation Performance Based on ANSYS

采用稻草板与聚苯乙烯泡沫板复合作为复合墙体的保温材料,利用ANSYS有限元软件模拟冬季条件下热量由室内通过该保温材料向室外的传递。通过单因素试验分析当P、S分别变化时,1型、2型、3型复合材料的温度场分布、导热系数和热流密度的改变;经过4因素7水平的均匀试验,分析当P、S同时变化时,2型和3型复合材料的保温性能相似;同时对复合材料的保温性能作出预测。稻草/PS层合复合材料保温性能的实际检测结果是1型复合材料的热阻为0.20,2型和3型复合材料的热阻相同,为1.13m2·(K·W-1),这与有限元分析的结果一致,表明ANSYS有限元法对于稻草/PS层合复合材料保温性能仿真分析具有一定的实际应用价值。

This experiment uses polystyrene cystosepiment and the straw board composite as the core board of wall material. Simulated using the ANSYS finite element software the quantity of heat when it transmits from the room to outdoor through the core board material under the winter condition. Analyses through a single-factor when P, S changes respectively, the temperature distribution, thermal conductivity and heat flux of typel, type 2 and type 3 ; Through four factors seven levels of uniform experiment, when P and S change at the same time, the insulation properties of type 2 and type 3 composite material are similar; and predict the thermal insulation properties of composite materials. The actual test results of straw/PS composite is the heat resistance of type 1 is 0.20 m^2· （K· W^-1 ）, type 2 and type 3 is 1. 13 m^2· （K· W^- 1 ）, and the same as the results of finite element analysis,so ANSYS can be used in heat preservation performance simulation analysis of polystyrene cystosepiment and straw board lamination compound materials.
