摘　　要：通过研究槽式聚光器结构的模态,进而分析其动力特性。首先,对槽式聚光器结构进行现场原型实测,测试聚光器竖向角为0°、30°、45°、60°和90°等5种工况,得到相关实测数据,并通过优泰软件分析得到其模态参数。然后,将实测结果与有限元软件Midas Gen得到的模态分析结果进行频率、振型等方面的对比,发现两者的结果吻合得较好。By studying the modal of trough concentrator structure, the dynamic characteristics are analyzed. First of all, carry out the prototype test of trough concentrator structure, and test the condenser vertical angle of five working conditions, which were 0° , 30°, 45° , 60° and 90° , obtain the experimental data, and get the modal parameters by Utekl analysis software. Then, the measured results and the modal analysis results of finite element software Midas Gen are compared between frequency and vibration mode, and find the results better.
