回转窑筒体应力分布研究

Study on stress distribution of rotary kiln's roll

由于回转窑筒体长、跨距大,为保证回转窑长期安全运转,要求筒体在横断面上应具有较大的刚度,在纵向则要有较好的柔性.基于此因,以筒体的应力、变形为切入点,对筒体的受力状况和应力分布进行分析研究,并运用ANSYS软件对筒体进行仿真分析,计算出筒体在实际运转过程中的应力和变形,找出筒体的危险薄弱面,从而为回转窑筒体的设计及调整提供理论指导.图5,表1,参7.

In order to guarantee rotary kiln long safe working, preferable rigidity in across section and suppleness in portrait are required because of long roll and big span. Based on this, the author take stress and deformation of roll as breakthrough point, study the press and stress distribution of roll by using finite element theory, calculate stress and deformation of roll by using ANSYS software, locate danger section of roll, it provides academic instruction for design and adjustment of rotary kiln roll.5figs.,1tab.,7refs.
