摘　　要：针对某型飞机液压系统能量转换装置PTU回油管存在踩踏,导致管路变形问题,重新进行了优化设计,并且进行了分析,结果表明:优化方案与原方案相比,避免了人为踩踏现象,避免了导管产生裂纹或泄露的可能,同时管路流体总压损失基本不变,无气蚀现象,重量减轻、噪音减弱等优点。according to a certain type of aircraft hydraulic system PTU（Power Transfer Unit）oil return pipeline are trample,resulting in pipeline deformation problems,work is carried out on the optimization design which are analyzed,the results show that the optimization scheme compared to the original scheme avoid the phenomenon of trampling,avoid that pipeline may crack or leak,and the total pressure loss of fluid pipeline is essentially the same,There are advantages including no cavitation phenomenon and lower weight and noise reduction.
