摘　　要：基于ANSYS软件采用"板梁结合"建模法建立大型秸秆锅炉的有限模型,计算和分析在自重、吊挂件重量、锅筒热膨胀位移等载荷作用下整体结构的变形。研究表明:吊挂件的重量、锅桶热膨胀位移是引起锅炉挠度超出设计规范的最重要原因,并且最大变形都出现在顶部,为进一步结构改进提供了参考。Establish a finite model of large straw boilers by the method of ＂plate-beam combination＂,calculate and analyze the deformation of the whole structure under the load of gravity,hanging weight,heat expansion displacement of pot bucket. Research shows：weight of hanging piece,thermal expansion displacement of drum is the important factor that causes the deflection of boiler to exceed the design standard,and the maximum deformation occurs at the top which providing a reference for further structural improvement.
