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.
