格栅增强沥青混凝土电热性能数值模拟
Nu merical simulation on electrothermal properties of geogrid reinforced asphalt concrete
摘要
Abstract
Carbon/glass fiber geogrid reinforced asphalt concrete is a new type of composite,which not only has good mechanical properties,but also shows excellent electrical conductivity.In this paper,the good electrother-mal properties of carbon/glass fiber geogrid reinforced asphalt concrete were used to heat the asphalt concrete slab,then melt snow and deice the ice.The environment temperature,the wind speed,the heating power and the thickness of ice are four main factors of the asphalt concrete slab deicing efficiency.In this paper,the deicing process of carbon/glass fiber geogrid reinforced asphalt concrete were simulated by ANSYS finite element software to predict deicing effect.The experimental values were used to verify the correctness of the numerical simulation. The results show that under various operating conditions,the numerical values are very close to the experimental values in the deicing process of carbon/glass fiber geogrid reinforced asphalt concrete.关键词
