为找出轧机主传动装置不同工况所产生的动力学行为及其应力变化规律和对传动装置不同零部件的影响,以UR轧机为研究对象,确定UR轧机主传动齿轮座约束变化对其传动系统关键零部件影响的仿真分析,用SolidWorks软件对轧机整体建模,再进行ANSYS有限元分析,并结合理论分析找出主传动装置应力变化规律。结果表明:万向节叉头和轧辊处存在应力传递不均匀现象,易导致零件的破坏。主传动装置的有限元分析为轧机的改进与优化提供理论参考。
In order to find out the dynamic behavior of the main drive of the rolling mill and its stress variation and influence on different components of the transmission, the UR rolling mill is taken as the research object to determine the restraint changes of the main transmission gear seat of the UR rolling mill on its transmission System simulation analysis of the impact of key components, using SolidWorks software to build the overall mill, and then ANSYS finite element analysis, combined with theoretical analysis to identify the main actuator stress changes. The results show that there is uneven stress transfer in the joints and rollers of the universal joints, which easily lead to the destruction of parts. The finite element analysis of the main transmission provides theoretical reference for the improvement and optimization of the rolling mill.
