摘　　要：在车载可折叠线性菲涅尔聚光镜场的研究中,为提高聚光集热器的性能,首先采用矢量分解的方法推导了镜场参数之间的数学关系。通过光学原理以及几何分析的方法,得出相邻镜元不发生阴影与遮挡的边界条件。结合车载镜场的具体尺寸,分析了镜场中各个参数对镜场聚光性能的影响,并通过编写C语言数值优化程序,得到镜场有效聚光面积最大时,镜场各个参数的尺寸值。最后利用光学仿真软件Tracepro建模仿真,得到集热器上平均光照强度最大时镜场参数的大小。研究结果为车载可折叠线性菲涅尔聚光集热系统设计提供了理论基础。The paper mainly study the vehicular foldable linear Fresnel lens. Firstly, we derived the mathematical relationship between the mirror field parameters, and then using the vector decomposition method, drew the boundary conditions between mirror elements without shadow and shelter. With the specific dimensions, we analyzed the influ- ence on the performance of the condenser with each parameter of the mirror field. We obtained the optimization parameters of the mirror when it gained the largest effective concentrating area through the program written in C language. Then we carried out some optical simulations to get the mirror field parameter when it cam to the maximum av- erage light intensity using software Traeepro. The optimization results from the linear Fresnel collector system provide a theoretical basis for the practical application.
