方法采用基于行程可变阻尼的滑轮缓冲器替代传统滑轮缓冲器，应用AMESim软件对2种滑轮缓冲器进行建模与仿真分析。
结果结果表明：基于行程可变阻尼的滑轮缓冲器可以有效提高阻拦装置的各项拦截指标，且对舰载机冲击载荷的适应性良好。与传统滑轮缓冲器相比，其阻拦索张力峰值降低25%，舰载机最大加速度降低23%。
结论研究结果可为进一步改善舰载机阻拦装置的性能提供理论参考。

Abstract:
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.
