摘　　要：以载荷为5000 kN的双辊摆辗机装配结构为基础,根据双辊摆辗传动件的负载规律,对双辊摆辗机的轧辊轴工况进行了研究。通过构建相关零部件的有限元模型,利用Hypermesh软件对轧辊轴进行刚度、强度分析,并根据分析结果对轧辊轴连接处进行了结构优化。对结构优化后的轧辊轴进行设备装配,并对装配后的双辊摆辗机进行生产调试。通过数次现场试验,发现双辊摆辗机运行稳定,未产生不良震动,该轧辊轴的刚度、强度符合要求,加工出的零件也达到了质量要求。验证了该轧辊轴设计的合理性、稳定性及可靠性,研究结果对于研发刚度和强度更高、安全性能更好的双辊摆辗机具有一定的指导作用。Based on the assembly structure of twin-roll rotary forging machine with load of 5000 k N,according to the load law of twin-roll rotary forging transmission parts,the working condition of roll shaft for twin-roll rotary forging machine was studied. Through the construction of finite element model for relevant components,the stiffness and strength of roll shaft were analyzed by software Hypermesh,and the structure of roll shaft connection was optimized according to the analysis results. Then,the roll shafts with optimized structure were assembled,and the twin-roll rotary forging after assembly was debugged. Furthermore,through several on-site tests,the results show that the twin-roll rotary forging machine runs stably without bad vibration,the stiffness and strength of roll shaft meet the requirements,and the processed parts also meet the quality requirements. Thus,the rationality,stability and reliability of the roll shaft design were verified.And the research results provide guidance for the development of twin-roll rotary forging machine with higher stiffness and strength and better safety performance.
