摘　　要：时效成形作为一种优异的航空制造工艺而备受青睐,但现有研究通常没有考虑大型热压罐加热速率差异性带来的成形质量问题。为此,提出了一种时效成形保温工艺优化方法。试验结果表明,保温时间调节算法能够降低升温速率波动对塑性应变的影响。The aging forming is favored as an excellent aerospace manufacturing process,but the existing research usually does not consider the forming quality problems caused by the difference in the heating rate of the large autoclave.For this reason,an optimization method of aging forming and heat preservation process was proposed.The experimental results show that the soaking time adjustment algorithm can reduce the effect of temperature rise rate fluctuation on plastic strain.
