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:
This article uses the characteristic value method to study the effects of non -pressure -flowing and medium -leaf frequency disorders and centrifugal effects on the boundary between the leaf closet bending, twisted coupling and non -stall tremor. The calculation results show that the leaves of the blade can delay the border of tremor vibration. Within a certain range, as the disorder increases, the border of the tremor has shifted backwards; the impact of different disorders on the tremor boundary is different.
