| 摘 要： | 提出了带冠叶盘的二维子结构循环非线性力学模型，该模型考虑了叶片振动方向与叶冠摩擦面之间的夹角，是对单自由度子结构循环模型的改进。同时给出了对应于二维子结构循环模型的运动方程并对基于这一模型的系统的响应特性进行了分析，特别研究了叶冠摩擦面角度的影响。

| Abstract: | A model of cyclic 2 DOF substructure of shrouded blisk is pressented.In this model the angle between shrouds interface and the direction of blade motion is considered.This is an improvement on the model of cyclic 1 DOF substructure.The equations of motion of the system based on the model are given at the same time.The general characters of forced vibration of the system especially the effect of the angle of shrouds interface are studied. |
