摘要
本文针对大型汽轮发电机定子的结构复杂性,在定子端部渐开线三维模型建立的基础上,通过Pro/E建立汽轮机定子绕组模型,包括渐开线端部绕组模型、定子绕组直线段以及压板等结构的建立和装配。并且通过Pro/E与ANSYS良好连接性,把建立的模型导入ANSYS中,进行了上层线棒和定子线棒整体装配结构的模态分析,为之后进行端部绕组及定子绕组的电磁振动等研究提供依据。
For the structural complexity of large turbine generator stator, on the basis of the three-dimensional model of the stator end involute, the turbine stator winding model was established in Pro/E： including the establishment of winding model of the involute end, the line segment of the stator winding and the pressing plates, then the stator winding and pressing plates are assembled.The article carries out the modal analysis of upper winding-bar and the assembly structures of stator line rod by the good connectivity of Pro/E and ANSYS, therefore providing the basis for the studying of electromagn-etic vibration of the end winding and stator winding afterwords.
