摘要：

在输电线路工程领域中，碗头挂板金具的锻造工艺往往直接影响其关键力学性能。研究碗头挂板金具的锻造成形工艺，对提高碗头挂板金具的关键力学性能具有重要的现实意义。对典型碗头挂板金具的锻造成形过程仿真分析可以基于DEFORM软件来实现。通过在DEFORM软件中完成碗头挂板金具的模型构建和有限元计算分析，对35钢与35CrMo钢两种材料的WS-32110碗头挂板金具的锻造过程进行仿真计算，分析了坯料成形过程中的金属流动情况、锻件的残余应力分布以及模具的磨损情况，确定了不同材料对锻造过程的影响。研究结果有助于掌握碗头挂板金具锻造成形的具体过程，进而针对其中的问题提出改进建议，为相关技术人员提供参考和借鉴。

In the field of transmission line engineering, the forging process of bowl head hanging plate hardware often directly affects its key mechanical properties, and the research on the forging process of bowl head hanging plate hardware has important practical significance for improving its key mechanical properties. Therefore, the simulation analysis of forging process for typical bowl head hanging plate hardware was realized based on software DEFORM, and the model construction and finite element analysis of bowl head hanging plate hardware were completed by software DEFORM. Furthermore, the forging processes of WS-32110 bowl head hanging plate hardwares for 35 steel and 35CrMo steel were simulated respectively, and the metal flow condition in the blank forming process, residual stress distribution of forgings and mold wear condition were analyzed to determine the influences of different materials on the forging process. The research results show that it is helpful to master the specific forging process of bowl head hanging plate hardware, and in response to the problems, the suggestions for improvement are put forward to provide reference and reference for relevant technicians.
