摘要

活塞连杆是汽车内部结构中不可或缺的部件。作为内燃机系统中的重要部件之一，活塞连杆需要满足高抗疲劳和抗冲击载荷的要求。锻造活塞连杆可获得较高的强度和抗疲劳性能。本研究在设计锻造模具时考虑了分模线、牵伸角、锻造公差、模具圆角半径、收缩率和废料等因素。通过有限元分析模拟了铝合金活塞杆锻造过程的工艺参数和模具尺寸。然后根据有限元模拟结果锻造出尺寸精度较高的铝合金活塞杆。

Die Design and Forging Analysis of Piston Connecting Rod of Aluminum Alloy

The piston connecting rod is an indispensable in the internal structure of the automobile. As one of the important components in the internal combustion engine system, the piston connecting rod needs to meet the requirements of high fatigue and impact load resistance. Forged piston connecting rod can obtain high strength and fatigue resistance. In this study, the parting line, draft angle, forging tolerance, die fillet radius, shrinkage and scrap are considered in the design of forging die. The process parameters and die dimensions of the forging process of aluminum alloy piston rod are simulated by finite element analysis. The aluminum alloy piston rod with high dimensional accuracy is then forged according to the finite element simulation results.

期刊介绍： Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
