能流密度测试仪机械结构动力学仿真分析

Energy Flow Density Tester Mechanical Structure Dynamic Simulation Analysis

由于太阳能分散性、不稳定性和利用效率低的自身缺点,增加了太阳能利用的成本。只有准确掌握聚光器聚光效率,测量实际接收到的太阳光辐射值,才能实现高效利用太阳能。这就需要设计一种精度较高的聚光器能流密度测试仪,国内外学者针对这一课题做了大量研究。该文主要是对目前使用的两种测试仪器结构进行动力学仿真计算,深入解析两种测试仪器机械结构的各自优缺点。

Because of the low efficiency of solar energy,the instability and the dispersivity of solar energy,the cost of solar energy utilization is increased.Only by grasping concentrators efficiency, measuring the actual received solar radiation values, We could achieve high efficiency of using solar energy.We need to design a high accuracy of condenser energy flow density measurement which domestic and foreign scholars have done a lot of research. In this paper,two kinds of test instruments are used to carry out dynamic simulation and calculation,and the advantages and disadvantages of the mechanical structure of the two instruments are thoroughly analyzed.
