摘要

针对高速运转带来的处于高温环境、狭小空间内复杂管路不平衡振动问题,开展航空发动机系统复杂管路的结构振动特性研究。从系统直管和弯管结构振动特性分析提出复杂管路结构数值建模方法,并基于航空发动机复杂管路一般具有对称的结构特点,对系统复杂管路从总体结构和径向结构角度开展振动特性分析与结构优化。分析结果表明:作为轴对称复杂管路结构,3个对称加载的总体结构呈现刚体模态,而20°的管路径向结构在基本加载下振动变形集中于异面支管,且总管增加不同载荷对其结构变形减小无正向影响,故从运行角度为狭窄空间内管路设置结构限制条件,有助于减少系统复杂管路运行故障的发生。

Abstract

Focus on the unbalanced vibration of complex pipe caused by high-speed operation under high temperature environment and narrow space, mainly analyze structural vibration characteristics of aero-engine complex pipes. From the analysis conclusion of the straight pipe and elbow, put forward structure numerical modeling method of system complex pipes to analyze vibration characteristics and optimize pipe structure of overall structure and radial structure in high pressure system based on the symmetric structural features of aero-engine complex pipe normally. The results show that overall structure by loaded symmetrically with 3 clamps presents the rigid body mode as symmetric complex pipes, while vibration deformation of 20 degrees radial structure under basic loading mainly concentrates on interspace branch pipes and deformation reduction couldn't be positively affected by increase of different loads in different positions of system manifold. So set structural constraints for pipes in narrow space from perspective of operation and maintenance, and help to reduce operation failure occurrence for complex pipes.
