Structure Analysis of Parabolic Trough Solar Concentrator Based on Fluidstructure Interaction

基于流固耦合技术对槽式太阳能聚光器进行结构分析,以ANSYS Workbench为仿真平台,采用单向流固耦合方法对聚光器结构进行仿真计算,获得聚光器在不同风速、不同角度下的结构特性。通过流固耦合分析,得到聚光器结构强度及刚度较为准确的数值,为其结构优化和运行维护提供有利的依据。

Analysis of parabolic trough solar concentrator structure based on fluid- structure interaction technique. The structural properties of the concentrator at different wind speeds and angles were obtained through the calculate simulation of the concentrator structure which was used the simulation platform of ANSYS Workbench, with one- way fluid- structure interaction method. From fluid - structure interaction analysis, we may obtain the values of the concentrator structure＇s strength and stiffness are more accurate, which provide favorable basis for its structural optimal, operation and maintenance.
