摘　　要：针对转子法兰-螺栓连接结构及其所处的载荷环境,考虑了其定位端面和定心柱面变形交互影响的力学过程,并提出了滑移损伤定量评估方法,基于此分析了复杂载荷作用下界面滑移损伤力学过程及其关键影响因素。研究表明:由于转子螺栓连接结构的界面非连续性,其定位端面和定心柱面间不同方向上的变形会交互影响,并且会受到工艺和装配特征参数的影响,实际发动机中由于上述参数随机特性,会导致连接结构界面滑移损伤具有显著的非确定性,引起连接结构发生附加变形并影响转子不平衡状态。The mechanical process of the interaction between the deformation of the positioning end face and the centering cylinder was considered for the rotor flange-bolted connection structure and its load environment,and a quantitative evaluation method for slip damage was proposed.Based on this,the mechanical process of interface slip damage under complex load and its key influential factors were analyzed.The results showed that due to the interface discontinuity of the rotor bolted connection structure,the deformation in different directions between the positioning end face and the centering cylinder could interact with each other,and could be affected by the process and assembly characteristic parameters.
