摘要
采用有限元法对叶片的动力特性进行分析时,利用叶片结构的循环对称特性能减小计算规模并且以较少高质量的网格获得理想的计算结果。根据循环对称算法对515 mm整圈叶片进行频率计算,其计算结果与实测结果吻合较好。
Using the finite element method to analyze the dynamic characteristics of the blade,the cyclic symmetry feature of the blade structure can reduce the calculation scale and obtain ideal calculation results with less high-quality grids.Analyzing the frequency of the 515mm ring blade with cyclic symmetry method,the calculation results coincides the measured results well.
