摘要:
聚光器是聚光型太阳能热发电系统的核心部件，其结构对风载荷的影响是十分敏感的。风载荷使聚光器结构产生位移，偏离理论的位置，从而对聚光效率产生影响；同时聚光器结构的设计直接影响生产成本。聚光效率、生产成本正是太阳能热电站建设的决定性因素。因此本文提出了风载荷下基于ABAQUS有限元软件优化聚光器结构的实现方法，通过此方法可以因地制宜的对不同形式的聚光器结构进行优化设计，从而达到减小聚光器对风载荷的位移，并实现结构材料的最优使用，降低生产成本。文章首先通过流体仿真计算出聚光器的风载荷值，然后将此值施加到聚光器上，计算出聚光器的位移以及关键部位的受力情况，调整结构设计与布置，从而达到优化目的。本文的方法为工程设计及验证提供了仿真计算优化模型，缩短设计周期，降低前期设计成本。
Solar concentrator is the key component of Concentrating Solar Power (CSP), which has great impact of the wind load and production cost. The wind load can make the condenser move thus deviating from the theoretical position and affecting its efficiency. The efficiency and cost are the most important factors to be considered in the process of building a Solar Thermal Power Plant (STPP). The main research of this paper is to optimize the concentrator structure with ABAQUS Finite Element analysis software on given wind load with different places and structure in order to reduce the displacement of concentrator, make full use of the material and reduce the cost. This article is to calculate the wind load value of the concentrator by simulating the system with the liquid software then obtains the displacement of the concentrator and analyzes the force of key parts. Therefore, we can adjust its arrangement and design to achieve the optimization purpose.
