Abstract:
Based on analysis of the work conditions and structural characteristics of the exterior pipeline of the aero-engine, a kind of cantilever-structure wire-rope isolator fitted to the exterior pipeline of the aero-engine is designed for supporting and damping purposes.By static experiments, the static hysteresis loop, the relationship of stiffness and amplitude, and the relationship between the energy dissipation coefficient and the amplitude are obtained.Analyses show that the wire-rope isolator presents obvious hysteresis characteristics, and the characteristics of the isolator, such as stiffness and damping, behave obviously nonlinearly when the amplitude value of deformation changes.At the same time, by changing the structure parameters of the wire-rope, the wire-rope isolators can be made with different functions to satisfy different work conditions.The research results have important reference values for the application of the wire-rope isolator on the exterior pipeline of an aero-engine.
在分析航空发动机外部管路的工况和结构特点的基础上, 设计了适合在发动机外部管路支承中使用的类似于悬臂梁结构的钢丝绳隔振器, 并对其进行了静态实验研究.静态实验中得到不同结构参数钢丝绳隔振器的滞迟回线、刚度-变形幅值关系曲线和能耗系数-变形幅值关系曲线.通过分析表明:钢丝绳隔振器呈现明显的滞迟特性, 隔振器的刚度、阻尼等性能随变形幅值变化表现出明显的非线性特性, 同时, 通过改变钢丝绳的结构参数, 可以获得具有不同性能的钢丝绳隔振器, 以满足不同工况的需求.研究结果对钢丝绳隔振器在航空发动机外部管路中的应用具有重要参考价值.
