摘要
高压转子是涡扇发动机核心部件,高压转子的振动问题一直以来都比较突出。探索、构建高压转子装配过程数据和转子最终技术状态以及振动响应之间的复杂规律或关联模型是至关重要的,也是非常迫切的。针对某型航空发动机高压组合转子(包括高压压气机转子和高压涡轮转子),基于堆叠机理和动力学建模方法,使用典型几何特性和不平衡参数,以振动响应为评价目标,对比分析3种高压转子连接装配工艺方法,并研究了端面跳动和不平衡量影响。为装配工艺优化提供了一定机理支持,并希望为整机振动排故提供借鉴或启发。
The high-pressure rotor is the core component of the turbofan engine,and its vibration problem is always prominent.It is very important and urgent to research the complex relationship between the assembly process data,the final technical state,and the vibration response for the high-pressure rotor.In this paper,a certain type of aero-engine highpressure combined rotor has been selected as the analysis object,and it is composed of a high-pressure compressor rotor and a high-pressure turbine rotor.The typical geometric characteristics and unbalanced parameters are used,and taking vibration response as the evaluation target,the comparative analysis of three high-pressure rotor connection and assembly methods have been conducted based on the stacking mechanism and dynamic modeling method.The influences of flat runout and unbalance on the vibration response have also been studied.The presented work provides the theoretical support for assembly process optimization to a certain extent,and hopes to supply some reference or inspiration for vibration trouble shooting of the aero-engine.
