摘　　要：在国内外陶瓷弹丸喷丸强化技术应用的基础上,结合某型飞机起落架的研制生产,通过不同材料的产品,用不同规格的陶瓷、铸钢弹丸喷丸进行对比试验,找出了喷丸强化对材料表面产生残余压应力的变化规律,以及强化效果与喷丸前表面状态的关系。从而优化了飞机起落架陶瓷弹丸喷丸的工艺参数,保证了过程质量受控,提高了产品寿命。The article finds out transformation rule and strengthened effect of residual compressive stress caused by shot peening strengthening on the surface of material, and the relationship with surface condition prior to peening, based on technical application of domestic and foreign ceramic shot peening strengthening, in combination with the development produc tion of aircraft landing gear, and by test compared ceramic shot of different strength with different material. Thus, optimize process parameter of ceramic shot peening of aircraft landing gear to ensure process quality control to improve the product life.
