| 摘 要： | 基于带冠叶盘的二维子结构循环非线性力学模型,用概率统计的方法讨论了带冠叶盘系统的非谐调对其固有特性以及受迫响应特性的影响,重点研究了叶冠间非谐调耦合程度的影响。叶冠间的耦合参数以及叶片的一阶频率参数被设为服从正态分布。给出了考虑干摩擦时系统最大振幅发生的概率、均值和标准差

| Abstract: | Based on a non linear model of cyclic 2 DOF substructure of shrouded blisk , the natural frequency and forced response of a mistuned shrouded blisk have been studied by using a statistic theory. The mistuned coupling strength between shrouds has been specially studied. The mistuned coupling strength between shrouds and the mistuned natural frequency of blade are considered to distribute normally. The probability, the mean value and the standard deviation of the largest response amplitude of the system have been given. |
