高强度铝合金中存在的残余应力引起工件变形与尺寸不稳定，是长期困扰工程界的技术难题。振动时效是一种能有效地降低残余应力和提高尺寸稳定性的技术，其中，振动时效工艺的掌握至关重要。介绍了振动时效工艺的基本原则，再用悬吊简化的振动台的方法对高强度铝合金厚板进行振动时效，展示了其具体的振动时效的工艺过程，达到了理想的时效效果。铝合金厚板的振动时效工艺直接影响着时效效果。

The deformation and instability caused by residual stress of high intensity aluminum alloy material is a problem, which is always puzzled in engineering .Vibratory stress relief (VSR) technology is a method for reducing residual stress and improving the size stability of member, and the mastery of vibratory stress relief technics is vitally important. This paper introduces the basic principle of vibratory stress relief technics ,then uses high intensity aluminum alloy thick plates to do VSR experiment by suspending simplistic vibration platform, which reveals the specific technics process of VSR and reachs to ideal aging results. The vibratory stress relief technics of aluminum alloy thick plates directly influence the aging results.
