| 摘 要： | 对某型机组末叶片建立三维实体模型并进行网格单元划分，利用有限元分析软件ABAQUS，考虑拉伸、弯曲、扭转和连接件的接触等条件，计算叶片在工作状态下的变形，通过自编程序，从计算结果中提取变形截面数据，可更加精确地得到变形量。

| Abstract: | 3D solid model of last stage blade of steam turbine is established and divided based on grid unit.The deformation of blade during operation will be calculated by finite element analyzing software ABAQUS for consideration of tension,bend,torsion and contact of connection parts etc.;therefore,the deformation section data could be gotten from the calculation result through self-coding program,which is the latest method for learning the deformation value more precisely. |
