摘要:
为了寻求沥青路面就地热再生合理的加热方式,依托卡罗泰康就地热再生机组,借助有限元软件ABAQUS对加热温度场进行了数值模拟.分析了加热方式、环境因素、加热机的操作参数及加热功率对沥青路面加热温度场的影响程度,提出了卡罗泰康就地热再生机组的理想加热方式.研究结果表明:相对于单程连续式的加热方式,间歇往复式的加热方式具有更好的加热效果; 不同的环境温度和风速对加热温度场的影响均比较显著,太阳辐射对加热温度场的影响较小; 加热机往返加热的往返距离、运行速度和往返次数共同影响着加热温度场,且存在最佳的组合; 不同加热机的加热功率也存在最佳的组合.采用有限元数值模拟方法可以方便地分析就地热再生的合理加热方式.
Abstract:
In order to investigate the appropriate heating method for hot in-place recycling, numerical simulation of the heating temperature field of asphalt pavement was carried out with the finite element software ABAQUS relying on Kalottikone hot in-place recycling train. The influence of heating mode, environmental factors, operating parameters and heating power of the preheaters were analyzed, and the ideal heating method of Kalottikone hot in-place recycling train was obtained. The results show that compared to one-way continuous heating mode, round-trip intermittent heating mode can acquire better heating effect. The influence of ambient temperature and wind speed on the heating temperature field are more significant while the influence of solar radiation is moderate. The round-trip distance, the running speed and the round-trip number of the preheater all influence the heating temperature field, and there exists an optimum combination of these parameters. There also exists an optimum combination of the heating power of different preheaters. Numerical simulation with finite element method can conveniently analyze the appropriate heating method for hot in-place recycling.
