摘要/Abstract

摘要： 航空涡轴/涡桨发动机动力涡轮转子是典型多支点支承、具有连接界面、质量/刚度分布不均匀的高速柔性转子系统，其连接结构力学特性和支承刚度的分散性可导致转子系统动力特性恶化。针对典型动力涡轮转子结构系统，指出不可恢复滑移、疲劳、摩擦等连接界面接触损伤是连接结构力学特性产生分散性的内在原因，提出了接触状态系数、接触应力、不可恢复变形能和接触摩擦功等工程适用的定量评估参数。通过对多支点柔性转子-支承系统临界转速分布及其对各支点支承刚度敏感度的影响规律分析，提出了基于支承刚度低敏感区择优的动力特性稳健设计方法，所提方法提高了转子结构系统的稳健性。

Abstract: The power turbine rotor of aero turbojet engine and turboprop engine is a typical high-speed flexible rotor structural system with multi-support, connecting interface and uneven mass/stiffness distribution. The dispersity of mechanical characteristics of joint structure and bearing stiffness can cause the dynamic cha-racteristics of the rotor structural system to deteriorate. According to the typical power turbine rotor structural system, it is pointed out that the interface contact damage, such as non-recoverable slip, fatigue and friction, is the intrinsic reason for the dispersity of the mechanical properties of the connecting structure, and the quantitative evaluation parameters including contact state coefficient, contact stress, non-recoverable deformation energy and contact friction work are put forward. Based on the analysis of the critical speed distribution of multi-support flexible rotor-bearing system and its influence on the stiffness sensitivity of each support, a robust design method of dynamic characteristics based on the selection of the low-sensitivity region of support stiffness is proposed, which improves the robustness of the rotor structure system.

Key words: robust design, connecting interface, contact damage, bearing stiffness, rotor system
