| Abstract: | A mechanical model of finite element method of the interference joint between the kiln roller and its axle was founded based on the structure characteristics of the kiln roller and its axle and their operation in situ. A numerical simulation of contact finite element method was made using ANSYS 6.1 for three different interference joints (H8/s7,H8/t7,H8/r7)of the kiln roller and its axle, the stress distribution law and deformation of the kiln roller and its axle under the condition of three different interference joints were derived, the major crack cause of the roller axle was found out, the optimum interference joint form of the kiln roller and its axle was determined, and the optimum design was provided for the kiln roller and its axle. |
