The study shows the proposed model can analyze vibration of continuous cover blades effectively, and visualizes nodal diameter vibration and nodal circle vibration very well. The proposed model and program can provide guidance for vibration design and vibration measurement of continuous cover blades. 算例表明,该模型可以有效计算成圈长叶片结构的振动特性,很好地反映成圈叶片结构的节径振动和节圆振动,为成圈叶片的振动设计和振动测量提供指导。
