中文摘要:
      概述了航空发动机不同联接结构的研究情况,重点针对螺栓联接结构动力学建模(包括对方形联接件和法兰结构的动 力学建模)、刚度计算方法、接触非线性、应力应变机械特性和试验研究情况,以及螺栓联接结构在转子系统中的应用展开详细论 述,分析了螺栓联接结构对旋转状态和动力学响应的影响,并对多螺栓装配体结构装配性能研究进行论述。提出应建立完备的螺栓 联接动力学特性研究理论,开展螺栓联接结构与其相应的装配体整体结构、螺栓联接动刚度和螺栓联接装配对结构动力学特性影响的深入研究
英文摘要:
      The research situation of different jointed structures of aeroengine was summarized. The dynamic modeling of bolted jointed structures (including the dynamic modeling of square and flange structure),stiffness calculation method,contact nonlinearity,stress-strain mechanical characteristics,experimental research and the application of bolted jointed structures in rotor system were discussed in detail. The influence of bolted jointed structures on rotation state and dynamic response was analyzed,and the research on assembly characteristics of multi-bolt assembly structures was discussed. It was suggested that a complete research theory should be established on the dynamic characteristics of bolted joint,and intensive study should be carried out on the influence of bolted jointed structures and its corresponding assembly body structures,bolted jointed dynamic stiffness and bolted jointed assembly on the structural dynamic characteristics
