回转窑筒体有限元分析

Finite Element Analysis of Rotary Kiln Body

利用有限元软件ANSYS计算回转窑筒体的结构应力和热应力分布状况,把筒壳、窑衬及物料作为一个系统,对筒体和窑衬进行分层、分段建模,研究筒体的轴向厚度、窑衬轴向的材质和物料对筒体结构应力的影响。分析不同厚度筒体的应力分布,得到筒体厚度对结构应力的影响规律。热应力分析结果表明:在筒体的支撑位置热应力较大。分析结果为回转窑筒体的设计和优化提供理论指导。

Taking the kiln shell,kiln liner,and the materials of rotary kiln as a whole system,ANSYS is adopted to analyze structural stress and thermal stress distribution of the kiln body.Regarding to lamination and partition of kiln shell and kiln liner,the various factors to stress of the kiln shell are researched,such as the thickness of shell,the different type of liner and the materials.The stress distribution of kiln shell influenced by thickness is analyzed.Then the influence of different thickness on the kiln body is obtained.In addition,the analysis result of thermal stress indicates that the thermal stress is very big at kiln body's support position.
