| 超声振动辅助成形技术是一项能场与物理场交叉的新兴绿色成形技术，因其可显著提高材料成形质量、减少材料成形缺陷，被广泛应用于材料加工领域。目前研究普遍认为，致使材料流动应力下降的体积效应与降低界面摩擦的表面效应是声塑性效应的主要作用机制。概述了超声振动辅助拉拔、拉深、渐进成形等先进成形工艺的原理，总结了3种典型超声塑性成形工艺的特点和研究进展。在此基础上，综述了超声振动辅助塑性机理下的应力叠加效应、声软化效应、残余效应以及动态冲击效应等体积塑性机制以及矢量效应与局部热效应的表面塑性机制，并分别对超声振动辅助体积塑性机制与表面塑性机制的研究进展进行了总结。其次，重点从体积效应和表面效应2个方面综述了超声振动辅助塑性成形本构模型，并从唯象模型和物理模型两方面总结了体积效应下本构模型的研究现状，同时总结了表面效应下摩擦模型的研究进展。最后归纳了超声振动辅助成形机理应用中存在的问题并对发展方向进行了展望。 |
| 英文摘要: |
| Ultrasonic vibration-assisted molding technology is an emerging green molding technology at the crossroads of the energy field and the physical field, which is widely used in material processing because it can significantly improve the quality of material molding and reduce the material molding defects. It is generally recognized that the volume effect, which leads to a decrease in the flow stress of the material, and the surface effect, which reduces interfacial friction, are the main mechanisms of the acoustic plasticity effect. The principles of advanced forming processes such as ultrasonic vibration-assisted drawing, deep drawing and progressive forming were outlined, and the process characteristics and research progress of three typical ultrasonic plastic forming processes were summarized. On this basis, the bulk plasticity mechanisms such as stress superposition effect, acoustic softening effect, residual effect, and dynamic impact effect, and the surface plasticity mechanisms such as vector effect and localized thermal effect under the ultrasonic vibration-assisted plasticity mechanism were reviewed, and the research progresses of the ultrasonic vibration-assisted bulk plasticity mechanism and the surface plasticity mechanism were summarized, respectively. Secondly, the current research status of the intrinsic model in ultrasonic vibration-assisted plastic forming was reviewed with focuses on both volume effects and surface effects, and the current research status of the intrinsic model under volume effects was summarized in terms of the image-only model and the physical model, while the research progress of the friction model under surface effects was summarized. Finally, the problems in the application of the ultrasonic vibration-assisted forming mechanism were summarized and the development direction was prospected. |
