摘要:
本文依据模态分析理论并结合规范的要求对某火力发电厂 600MW汽轮发电机的框架式基础1:10模型振动性能进行了研究,采用白噪声随机激振法对该结构进行了空间整体模态分析,从实测数据中获得了动力特性数值。通过与ANSYS有限元软件数值计算结果的对比,表明理论分析模型的可行性。研究结果将为发展汽轮发电机框架式基础的设计原则和优化动力设计方法提供参考。
Abstract:
Based on the modal analysis theory and the requirements of the codes, some research work about the dynamic behavior of 600MW turbine-dynamotor frame foundation 1:10 model in a powerstation was done. More practical dynamic character values were obtained from factual data by 3D modal analysis of white noise random excitation method. The feasibility of theoretic analysis model is proved by the comparison with computational results of ANSYS. The research results will afford reference to developing the design principle and optimized dynamic design method of turbine-dynamotorframe foundation.
