1.计算方法及其实验验证 本文用分析法见文献[1],这里以WS9高压二级涡轮转子叶片(简称WS9叶片)为例来说明方法的特点。该转子轮盘上均匀安装110片叶片,组成具有循环对称接触结构的叶片环,有接触表面的循环对称结构。据此,可将图1所示的一片叶片取作基本段分析,但同时必须在该叶片一般有限元刚度方程中引入缘板及叶冠的循环对称接触表面(叶冠的A1侧面与A2侧面,以及缘板的B1侧面与B2侧面)处的循环对称接触 1. Calculation method and its experimental verification In this paper, see the literature [1], here to WS9 high pressure two turbine rotor blades (WS9 blades) as an example to illustrate the characteristics of the method. The rotor disc is evenly mounted with 110 blades to form a blade ring with a cyclical symmetrical contact structure and a cyclically symmetrical structure with a contact surface. Therefore, one blade shown in Fig. 1 can be taken as the basic segment analysis. At the same time, the circular symmetrical contact surfaces of the edge plate and the canopy must be introduced into the general finite element stiffness equation of the blade (the A1 side and the A2 side , And the B1 side of the edge plate and the B2 side)
