摘　　要：随着当代科学技术的快速发展,使用工程计算软件对工程设计的可靠性进行校核已经成为一种十分有效的方式和手段.本文基于现代有限元分析专业软件ANSYS,对灯泡贯流式发电机机组贴壁式定子间隙进行研究,在结构及热两个领域对定子机座和定子铁芯进行耦合分析研究以确定间隙设计的可靠性,分析结果表明此种灯泡贯流式发电机贴壁式定子间隙设计合理.With the rapid development of modern technology, verifying the reliability of engineering designs by engineering calculation software has been an effective manner and measure. In this article, based on analyzing and investigating a stator clearance of bulb turbine by finite element analysis software ANSYS, the authors study the stator base and the iron core of the stator both from the view of structure and from the view of thermal field in order to confirm the reliability of the stator clearance design .At last, the result shows that the stator clearance design of bulb turbine is reasonable.
