中文摘要：
采用自制单曲率蠕变成形模具和振动试验平台，在淬火态7055铝合金板材蠕变时效成形过程中引入振动作用。研究了成形曲率、温度与振动方式对试样回弹量、力学性能和微观组织的影响。结果表明：在一定时间范围内，振动蠕变成形加速应力松弛，降低回弹量；促进铝合金的强化相析出且分布更加弥散；提高强度。在本文的试验条件下（120℃／24h），引入振动使峰值时效试样的强度提高7％，回弹量降低12．3％。
英文摘要：
The Vibratory field was applied to the process of creep aging forming of water-quenched 7055 aluminum alloy sheets, which were operated on the self-made single curvature die and vibratory platform. The effects of temperature and vibration mode on the spring- back value,mechanical properties and mierostructures were investigated. The results show that within a certain range of time, the spri- ngback value is reduced and the rate of stress relief is accelerated. Meanwhile, the precipitation is promoted and the distribution of pre- cipitates is more dispersion, as a consequence, the strength of the alloy is improved on a considerable extent. On the experimental con- ditions of this paper, the strength of the VCAF specimens is increased with 7% , and the springback value is decreased with 12.3%
