摘要

针对典型航空 21~28MPa 液压系统钛合金导管组件制造过程，基于导管左/右弯数控弯曲技术、管路光学测量技术、无扩口滚压连接技术、导管组件性能测试技术等导管组件制造关键技术，提出了航空液压系统导管组件制造技术方案，并在民机典型液压系统高强钛合金（Ti–3Al–2.5V）导管组件制造过程得到了验证。结果表明，采用以上技术途径，提高了钛合金液压系统导管组件的制造精度、效率、服役的可靠性，为解决航空液压系统“跑、冒、滴”问题提供了新的技术思路。

Abstract

A manufacturing methodology is provided for typical titanium alloy tube assemblies in 21–28MPa aeronautic hydraulic pressure system

based on tube numerical control left/right bending technology

tube optical measurement technology

tube flareless internal rolling connection technology and quality test technology of titanium alloy tube assemblies. This methodology is verified by a manufacturing process of the high strength titanium alloy (Ti–3Al–2.5V) tube assemblies for a typical hydraulic pressure system in a commercial plane. It can be found that the manufacturing precision

efficiency

and reliabilities of the titanium alloy tube assemblies are enabled by using this methodology

and a new technology way can be found for solving the leakage problems in aeronautic hydraulic pressure system.
