Dynamic modeling and simulation of sheave damper based on AMESim software

  Objectives  Considering the shortcomings of the traditional sheave damper in buffer performance and the peak value of the greatest cable tension,

  Methods  this paper presents a sheave damper with variable damping according to piston displacement as a replacement for the traditional sheave damper, and AMESim software is used for the modeling and simulation.

  Results  The results show that the new sheave damper can significantly improve the arresting gear performance indicators, and has better adaptability for aircraft impact load. Compared with the traditional sheave damper, the new method can reduce cable tension by 25% and reduce the maximum deceleration of aircraft by 23%.

  Conclusions  As such, the research in this paper can provide a theoretical reference for improving the performance of aircraft arresting gear.
