回转窑结构分析

Structure Analysis for Rotary Kilns

以某大型回转窑为研究对象,对其进行静力学分析和热-结构耦合分析。通过对回转窑的局部模型分析,确定侧壁的薄弱位置,同时对局部模型中侧壁壁厚进行优化,得到应力随壁厚变化的分布规律。通过对回转窑整体模型进行分析得到整体挠度及出料口附近的应力分布情况,分析结果可为回转窑的设计优化提供参考。

Statics analysis and thermal-structure coupling analysis carries out on a large rotary kiln.The analysis with the local rotary kiln model determines the weak position on the side wall and optimizes the side wall thickness to obtain the stress distribution changing with the wall thickness.The analysis with the entire rotary kiln model finds out the overall deflection and the stress distribution near the discharge port.The analysis result can be considered as reference for the design and optimization of rotary kilns.
