| 摘 要： | 本文用特征值法研究了不可压流中叶片频率失调阶次及离心力效应对叶橱弯、扭耦合非失速颤振边界的影响。计算结果表明:叶片失调可延迟颤振边界,在一定范围内,随着失调幅度的增大,颤振边界愈向后移;不同的失调阶次对颤振边界的影响不同,影响的大小取决于叶片颇振时的振动阶次:计及离心力效应后,叶栅颤振边界后移。

| Abstract: | The eigenvalue method is presented for determining the effects of blade mistiming (mistiming amplitude, mistuning order) and centrifugal effects on cascades flutter boundaries in incompressible flow. Result presented illustrate that mistuning has a beneficial effect on the cascade flutter; With the mistuning amplitude increasing, the flutter boundaries more move backward; Different mistuning orders have different effects on flutter boundaries, depending on in which order modal cascade flutter. |
