摘要/Abstract

摘要： 先进航空发动机中，往往采用带中介轴承的双转子支承方案以减少承力框架数目、降低整机重量。但是，中介轴承-支承结构系统具有典型非连续特征，工作时会受到双转子复杂运动状态影响，导致中介轴承-支承结构系统工作载荷环境恶劣多变，极易引发结构损伤。这里以中介轴承-支承结构系统为研究对象，分析了转子运动状态变化对轴承-支承结构系统载荷环境的影响，提出了面向结构完整性的轴承-支承结构设计要求。研究表明，不同转子运动状态下，轴承构件运动交互影响，使结构系统受到冲击激励、转子倍频激励、双转子转速组合频率激励、转子-保持架转速调制频率激励等复杂载荷激励作用，使支承结构约束特性偏离设计值直至发生失效，因此需要在结构设计中考虑不同转子运动状态影响，基于此对结构力学特性进行校核和优化设计。

Abstract: In advanced aero-engines, a dual-rotor support scheme with an intermediate bearing is often employed to reduce the number of load-bearing frames and decrease the overall weight of the engine. However, the intermediate bearing-support structure system exhibits typical discontinuous characteristics and is influenced by the complex motion states of the dual rotors during operation, resulting in a harsh and variable load environment for the intermediate bearing-support structure system, which can easily lead to structural damage. This study focuses on the intermediate bearing-support structure system, analyzing the impact of changes in rotor motion states on the load environment of the bearing-support structure system, and proposes de-sign requirements for the bearing-support structure aimed at ensuring structural integrity. Research indicates that under dif-ferent rotor motion states, the interactive effects of bearing component motions subject the structural system to complex load excitations such as impact excitation, rotor harmonic excitation, combined frequency excitation of dual-rotor speeds, and rotor-cage speed modulation frequency excitation. These excitations cause the constraint characteristics of the support struc-ture to deviate from the design values until failure occurs. Therefore, it is necessary to consider the influence of different rotor motion states in the structural design and to verify and optimize the mechanical characteristics of the structure based on these considerations.
