从整圈自锁阻尼长叶片的有限元分析方法入手,着重对循环对称边界条件进行了讨论,将不同分析方法得到的计算结果进行了比较,发现如果计算参数设置得当,使用循环对称的边界条件可以在很大程度上节约计算资源,同时还能得到和其他分析方法精度相当的计算结果。
Starting from the finite element analysis of a full circle self-locking damped long blade, the circular symmetry boundary conditions are discussed. Comparing the calculation results obtained by different analysis methods, it is found that if the calculation parameters are properly set, Can save a large amount of computational resources, but also get the same accuracy as other analytical methods.
