摘　　要：分析了采用0Cr18Ni9超高强度钢制作飞机起落架胀管的材料特性,使用ELITE Plus 8/51M数控车床、YX32-250T四柱液压机和热处理炉对产品进行试制,并通过CMT6503微机控制电子万能试验机进行拉伸试验,来寻求飞机起落架胀管的最优制造工艺。根据试验结果,对产品设计缺陷进行改进,确定固溶处理工艺,对产品制作工艺流程进行优化,制定了采用0Cr18Ni9超高强度钢制作飞机起落架胀管的最优制作工艺。试验结果证明,该工艺措施有效,胀管试制后拉伸验证合格率达100%。Analyzed the material properties of 0Crl8Ni9 expanding of aircraft landing gear, use ELITE Plus 8/51M CNC lathes, YX32-250T hydraulic machine, heat treatment furnace for try making products, and tensile test was conducted by CMT6503 com- puter-controlled electronic universal testing machine ,to seek optimal manufacturing process of expanding of aircraft landing gear. According to the test results, improved product design defects, determined the solution treatment, formulated the optimal produc- tion process of 0Crl8Ni9 expanding. The experimental results show that the process measures effective, and the passing rate of 100 % after the trial expander stretching verification.
