【摘要】：随着中国的迅速发展,高等级高速公路在发展中占据越来越重的承载作用,根据国家公路相关规划,预计到2030年公路交通运输需求将会在现阶段基础上提高一倍。当沥青路面工作一段时间后,由于自然环境与频繁负载的原因会导致高等级高速公路出现坑槽、裂缝、龟裂、拥包与裂块等不同形式的病害现象,这就导致了其需要合理的修复与养护服务,以保证其对运输需求的承载工作。本文在研究沥青路面微波热再生技术的作用机理基础上,通过设计合理的沥青路面微波加热装置,从而对沥青路面进行合理的修复与养护工作,用以延长沥青路面的工作寿命。论文首先研究沥青路面再生技术概况,然后研究微波热再生机理,分析沥青路面微波加热的特点以及效率等关键问题,为提高沥青微波加热技术的加热区均匀度与加热区工作效率提供理论依据;本文研究喇叭了辐射器,根据微波加热原理设计合理参数并进行初步分析。论文对加热装置的工作原理、系统组成与优化参数进行相关的研究,并在此基础上进行了对应的实验。从而得出了喇叭辐射器与加热装置的加热区均匀度特性。为了进一步改善加热均匀度,本文提出了径向螺旋天线辐射器。详细介绍了径向螺旋行的设想、优化方案与优化参数,研究分析了径向螺旋天线辐射器的特点,从加热区均匀度、加热效率等角度对两种辐射器进行了相关对比研究与实验,获得了比喇叭辐射器更好的均匀加热区与更高的工作效率。本文为了对辐射器加热区的均匀度与转换效率问题进一步的优化,提出采用电磁超材料结构提高有效热转换效率。论文对EBG结构的设计进行了详细说明,给出了新型辐射器的模型结构,并研究分析了新型辐射器的工作特性。与前两种辐射器相对比,得到了更好的加热区均匀度与更高的能量转换效率。本文优化了喇叭天线设计、提出径向螺旋天线辐射器,采用电磁超材料结构等方法有效提高了微波沥青路面加热的均匀度和效率。为了进一步缩短加热时间,达到大规模工程使用化的目的,结合多种技术,需要进行下一步研究。
[Abstract]:With the rapid development of China, high-grade highways play a more and more important role in the development. According to the national highway related planning, it is expected that the demand for highway transportation will double on the basis of the present stage by 2030. When the asphalt pavement works for a period of time, due to the natural environment and frequent load, different forms of diseases, such as potholes, cracks, bags and cracks, will occur in the high-grade expressway. This led to the need for reasonable repair and maintenance services to ensure its transport needs to carry the work. Based on the study of the mechanism of microwave thermal regeneration technology of asphalt pavement, this paper designs a reasonable microwave heating device for asphalt pavement, so as to carry out reasonable repair and maintenance of asphalt pavement in order to prolong the working life of asphalt pavement. This paper first studies the general situation of asphalt pavement regeneration technology, then studies the mechanism of microwave thermal regeneration, analyzes the characteristics and efficiency of microwave heating of asphalt pavement, and so on. It provides a theoretical basis for improving the uniformity of heating zone and the working efficiency of heating zone of asphalt microwave heating technology. In this paper, the horn radiator is studied, and the reasonable parameters are designed according to the principle of microwave heating and the preliminary analysis is carried out. In this paper, the working principle, system composition and optimization parameters of the heating device are studied, and the corresponding experiments are carried out on this basis. Thus, the uniformity of heating zone between horn radiator and heating device is obtained. In order to improve the uniformity of heating, a radial spiral antenna radiator is proposed in this paper. This paper introduces in detail the assumption, optimization scheme and optimization parameters of the radial spiral antenna radiator, studies and analyzes the characteristics of the radial spiral antenna radiator, and makes a comparative study and experiment on the two kinds of radiator from the point of view of the uniformity of the heating zone and the heating efficiency. Better uniform heating zone and higher working efficiency are obtained than horn radiator. In order to further optimize the uniformity and conversion efficiency of the radiator heating zone, this paper presents an electromagnetic supermaterial structure to improve the effective heat conversion efficiency. In this paper, the design of the EBG structure is described in detail, the model structure of the new radiator is given, and the working characteristics of the new radiator are studied and analyzed. Compared with the former two radiators, better uniformity of heating zone and higher energy conversion efficiency are obtained. In this paper, the design of horn antenna is optimized, and the radial spiral antenna radiator is proposed. The uniformity and efficiency of microwave asphalt pavement heating are improved by using electromagnetic supermaterial structure and so on. In order to further shorten the heating time and achieve the purpose of large-scale engineering usage, combined with various technologies, the next step needs to be studied.
