摘要
针对现有的裂纹转子模型的一些缺陷，提出了较为合理的新的有限元模型，然后提出了采用谐波平衡法求解裂纹转子动力学方程的新方法．从而使裂纹转子动力特性的精确的定量分析成为可能．
A new and more resonable model is presented for a cracked rotor by means of improving the old one withfinite element analysis. In addition. the harmonic balance method is applied first to the solution for dynamic equation setof a cracked rotor to enable its dynamic behaviour to be more accurate with effective monitoring and detection availableto cracks.
