基于Soltrace的聚光碟面反射目标靶设计方法

SOLTRACE BASED ALIGNMENT TARGET DESIGN METHOD FOR CONCENTRATIVE DISH

以Soltrace为基础,利用该软件的三坐标系统对碟式聚光单元进行建模,结合其光线追踪技术,给出可用于指导镜面精确安装调节以实现太阳光高效均匀汇聚的调光目标靶的设计方法。理论分析表明该方法能够有效地结合碟式聚光系统及其接收器的机械结构,在保证汇聚光完全通过热接收器入口的前提下,在发动机热头处获得能量集中且均匀分布的光斑。以此目标靶为基础的碟式聚光系统的安装调节结果表明该方法的正确性和有效性。

By utilizing the Global-Stage-Element coordinate systems provided by Sohrace, facets that form parabola shape can be modeled and adjusted. Combining the integrated dishes composed of mirror light tracing method of the software, this paper provides a way to design target positions of reflected light from mirror facets, which is used to guide dish alignment in order to get required heat source. Theoretical analysis shows that the presented method can easily integrate dish structure and give highly concentrated evenly distributed heat source on the receiver plane without any lose of energy at the entrance of the receiver. Practical dish alignment done with the target positions validates our method.
