摘　　要：[目的]针对传统滑轮缓冲器的缓冲性能不足以及阻拦索张力峰值过大的问题,[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。[Objectives]Considering the shortcomings of the traditional sheave damper in bufferperformance and the peak value of the greatest cable tension,[Methods]this paper presents a sheavedamper with variable damping according to piston displacement as a replacement for the traditional sheavedamper, and AMESim software is used for the modeling and simulation.[Results]The results show thatthe new sheave damper can significantly improve the arresting gear performance indicators, and has betteradaptability for aircraft impact load. Compared with the traditional sheave damper, the new method canreduce cable tension by 25% and reduce the maximum deceleration of aircraft by 23%.[Conclusions]Assuch, the research in this paper can provide a theoretical reference for improving the performance ofaircraft arresting gear.
