摘　　要：研究了2024铝合金化铣试验件与化铣+激光喷丸试验件的高低周疲劳特性。结果表明:在高周疲劳时,化铣+激光喷丸试验件的疲劳寿命优于化铣件;在低周疲劳时,化铣试验件的疲劳寿命则优于化铣+激光喷丸试验件。High-cycle and low-cycle fatigue life of chemical milling aluminum alloy 2024 test species with and without LSP was investigated by experiment. The results show that the chemical milling aluminum alloy 2024 test species with LSP perform better than the ones without LSP in high-cycle fatigue while in low-cycle fatigue, the test species without LSP perform better.
