Abstract

Considering the complexity of the radial forging process, the study of dynamic and thermodynamic parameters is of great importance. With the severe deformation of a workpiece in a plastic state, the effects of all parameters affecting the final geometry of the forging pipe need to be optimized. Thus, the mathematical model of the process is based on visco-plastic material, taking into account thermomechanical coupling and the surface properties during forging, including the hardness of the workpiece and friction. The results present the effects of a die angle on residual stress, total wear, and contact force, leading to ideal operating conditions and the ideal design of machine parts. In order to ensure the accuracy of the calculations and predictions made through software, a hardness test was performed experimentally, which showed the hardness curve of the microstructure and the strain of the workpiece. This indicates the consistency and accuracy of the results obtained from both methods. In order to improve the process and the tube employed, using an optimized die is recommended.

基于硬度准则的径向锻造参数分析方法的发展

考虑到径向锻造过程的复杂性，对其动力学和热力学参数的研究具有重要意义。由于工件在塑性状态下的剧烈变形，需要对影响锻造管最终几何形状的所有参数进行优化。因此，该过程的数学模型基于粘塑性材料，考虑了锻造过程中的热力耦合和表面性能，包括工件的硬度和摩擦。结果表明，模具角度对残余应力、总磨损和接触力的影响，从而得出理想的工作条件和机械零件的理想设计。为了保证软件计算和预测的准确性，进行了硬度试验，得到了工件显微组织与应变的硬度曲线。这表明了两种方法所得结果的一致性和准确性。为了改进工艺和所用的管材，建议使用优化的模具。

期刊介绍： The Journal of Mechanical Engineering & Sciences "JMES" (ISSN (Print): 2289-4659; e-ISSN: 2231-8380) is an open access peer-review journal (Indexed by Emerging Source Citation Index (ESCI), WOS; SCOPUS Index (Elsevier); EBSCOhost; Index Copernicus; Ulrichsweb, DOAJ, Google Scholar) which publishes original and review articles that advance the understanding of both the fundamentals of engineering science and its application to the solution of challenges and problems in mechanical engineering systems, machines and components. It is particularly concerned with the demonstration of engineering science solutions to specific industrial problems. Original contributions providing insight into the use of analytical, computational modeling, structural mechanics, metal forming, behavior and application of advanced materials, impact mechanics, strain localization and other effects of nonlinearity, fluid mechanics, robotics, tribology, thermodynamics, and materials processing generally from the core of the journal contents are encouraged. Only original, innovative and novel papers will be considered for publication in the JMES. The authors are required to confirm that their paper has not been submitted to any other journal in English or any other language. The JMES welcome contributions from all who wishes to report on new developments and latest findings in mechanical engineering.
