| 摘 要： | 为了提高微波加热沥青混合料的效率和温度分布的均匀性,设计了一种角锥喇叭辐射型加热器.运用能量守恒定律和天线辐射原理,建立了喇叭口面尺寸和天线长度设计原则.采用IE3D进行了结构建模和仿真运算,结果表明在喇叭口面尺寸一定的前提下,天线长度缩短是改善加热均匀性的主要因素;当天线长度不变而口面尺寸减小时,其驻波比减小,辐射效率提高;口面离沥青路面距离增加时,辐射效率下降.对这种结构加热器进行了实验,采用网格测温法测出了沥青试样表面温度分布并进行了Matlab模拟,实验结果与仿真具有较好的一致性.

| Abstract: | In order to improve the efficiency of heating and the uniformity of temperature distribution in recycling asphalt mixtures,a pyramidal radiation heater is designed.The principles of designing horn surface size and antenna length are established according to the law of energy conservation and microwave antenna radiation theory.Modeling and simulation are carried out using IE3D software.The simulation results demonstrate that,with a fixed horn surface size,the shortened electric antenna length is the main fac... |
