| 摘 要： | 采用DEFORM软件对U型截面铝合金锻件固溶后淬火入水方式进行了数值模拟分析,研究了4种入水姿态和自由落体、5 m/s及2 m/s的入水速度对锻件温度场和残余应力的影响规律。结果表明,锻件入水姿态和入水速度对残余应力的影响显著,该锻件以U型面旋转90°姿态和自由落体入水时,残余应力值最小且分布最均匀。

| Abstract: | Water-entering modes during quenching for a U-shape sectioned aluminum alloy forging after solution treatment were simulated and analyzed based on DEFORM software. The influence of four different water-entering modes of the forging and water-entering speeds of free-falling, 5 m/s and 2 m/s on the temperature field and residual stress was studied. The results reveal that the water-entering mode and speed of the forging dramatically influence the residual stress. When the forging is rotated 90° in U-face and free falls into water, the residual stress is the smallest and most evenly distributed. |
