摘　　要：基于ANSYS Workbench软件中的结构静力分析模块建立密炼机转子端面动静密封环的有限元模型,利用仿真技术分别对动静密封环端面直接接触和介质接触进行摩擦静力学分析。结果表明:动静密封环接触端面压力最大,导致端面摩擦力最大,磨损最为剧烈;混炼物料泄漏会使动静密封环端面接触由直接接触变为介质接触,端面摩擦磨损加剧,易导致端面动静密封环损坏甚至失效。Based on the static structure module in the ANSYS Workbench software,the finite element model of the dynamic and static sealing ring of the mixer rotor end face was established,and the end face direct contact and medium contact of the dynamic and static sealing ring were analyzed based on friction statical mechanics using simulation technology. The results showed that the pressure at the contact end face of the dynamic and static sealing ring was the highest,so the friction force of the end face was the highest,and the wear was the most severe.The leakage of mixed materials would cause the end face contact of the dynamic and static sealing ring change from the direct contact to medium contact,and the friction wear of the end face became more severe,which could easily cause the dynamic and static sealing ring to be damaged or even fail.
