摘  要:介绍了一种新型液压缓冲拦阻器原理,制造工艺与活塞发动机一样,拦阻距离不受限。按照流体力学理论建立了拦阻力、空气阻力、飞机升力数学模型,利用SIMPACK软件建立了统一的动力学模型;根据国内文献对MK7-3型拦阻器性能的研究成果,对比分析了舰载机以不同质量、速度着舰的拦阻动力学过程。仿真结果表明:所设计的曲柄滑块拦阻器动力学性能良好,既能进行定长拦阻也能自由拦阻。The principle of a new type hydraulic arresting gear was introduced,which has the same manufacturing process as the piston engine while its arresting distance is not limited.The mathematical models for the arresting force,air resistance and aircraft lift were established according to the theory of fluid mechanics,and then a unified dynamic model was established by SIMPACK software.According to the domestic literature about the MK7-3 type arresting gear performance research results,a comparative analysis of arresting kinetic processes under different aircraft weight and landing velocity was carried out.The simulation results show that the crank slider damper has good dynamic performance,which is able to perform both the fixed-length arresting and the free arresting.
