| 中文摘要: |
| 介绍了振动时效法消除残余应力的机理以及在薄壁铸件上的应用。通过对振动时效工艺参数，包括激振点、支撑点、激振频率、激振力和激振时间等的分析，优化出了薄壁铸件的振动时效工艺。振动时效后薄壁铸件残余应力降低35%以上，应力分布得到了均化，同时与热时效相比，节约工艺成本70%以上，大大地缩短了处理时间。 |
| 英文摘要: |
| The mechanism of vibration stress relief (VSR) and its application in the thin-walled casting were introduced. VSR process parameters including vibration excitation point, support point, excitation frequency, excitation force, excitation time and so on, were analyzed to optimize the process of vibration-aging. After VSR the residual stress reduced above 35%.The stress distribution became more homogeneous. Compared with the heat aging, VSR saved the process cost above 70% and reduced the process time. |
