摘　　要：振动辅助塑性成形技术是近年来振动利用工程在塑性成形领域发展起来的一门新兴边缘交叉学科,振动场与塑性力场的耦合能产生诸如材料流动应力下降的体积效应和接触面摩擦力降低的表面效应。综述了振动辅助拉拔、拉深、挤压、轧制等成形工艺原理,分析了4种典型塑性成形工艺在振动场下的宏观表现、工艺特点和研究进展。在此基础上,围绕应力叠加效应、振动软化效应、振动残余效应,对振动辅助塑性成形机理方面的研究进行了总结;基于振动减摩和振动场下摩擦模型,对振动辅助塑性成形在界面摩擦行为方面的研究进行了分析;最后,对振动辅助塑性成形技术的发展前景进行了展望。In recent years, vibration-assisted plastic forming technology has become an emerging interdisciplinary subject due to the development of vibration utilization engineering in the field of plastic forming, and the coupling of vibration field and plastic force field can produce volume effect of reducing flow stress of material and surface effect of reducing friction at the interface. Therefore, the forming process principles of vibration-assisted drawing, deep drawing, extrusion and rolling, etc. were summarized, and the macroscopic performance, process characteristics and research progress of four typical plastic forming processes were analyzed under the vibration field. On this basis, the research on the mechanism of vibration-assisted plastic forming was summarized around stress superposition effect, vibration softening effect and vibration residual effect, and the interface friction behavior of vibration-assisted plastic forming was also analyzed based on antifriction by vibration and friction model under the vibration field. Finally, the development of vibration-assisted plastic forming technology was prospected.
