| 摘 要： | 针对叶片动频率陀螺特征值问题，首先将其转化为等价的广义实对称矩阵特征值问题，然后用拟波前子窨迭代法进行求解。在经转轴算例验证之后，用此方法某型压缩机工作叶片的动力特性，发现其有发生内共振的可能，而陀螺阻尼则起一定的致稳作用。

| Abstract: | The gyroscopic eigenproblem concerning the dynamic frequencies of compressor blades is shown to be equivalent to the generalized eigenproblem of two symmetric real matrices. A subspace iteration algorithm is applied to solve the problem using a quasi front method. Applications are made to a spinning shaft and the compressor blades. Possibile inner resonances could be damped to the gyros copic motion. |
