摘　　要：海上作业直升机快速回收系统集辅助着舰、快速安全系留、牵引、放飞等功能于一体,是目前国内外最先进的直升机舰面辅助系统,对于提升直升机的生命力和出动回收效率意义重大。海上作业直升机降落到舰船甲板上时,快速回收系统需要对直升机进行快速捕获系留,以确保降落过程中的直升机安全。从理论计算和基于Adams的动力学仿真两方面对海上作业直升机在舰面的系留安全性进行了分析,并在仿真中提出了一种基于活塞套筒模型和用户子程序的直升机机轮减震器建模方法。理论计算表明,当直升机前轮胎与甲板之间摩擦因数大于0.1363时,直升机不会发生失稳打转;仿真结果表明,六级海况条件下,快速回收系统可以通过快速系留装置对直升机进行持续安全系留,直升机机身轴线摆动角度不超过±3°,上述理论和仿真计算为高海况条件下的直升机系留安全性提供了有力支撑。The rapid recovery system for shipborne helicopters integrates functions such as auxiliary landing,fast and safe tethering,traction,and release.It is currently the most advanced shipborne helicopter assistance system at home and abroad,and plays an significant role in enhancing the vitality and combat effectiveness of helicopters.When a shipborne helicopter lands on the deck,the rapid recovery system needs to quickly capture and secure the helicopter to ensure its safety during the landing process.The tethering safety of shipborne helicopters on the deck is analyzed from both theoretical calculations and Adams based dynamic simulations,and a modeling method for helicopter wheel shock absorbers is proposed based on piston sleeve models and user subroutines in simulations.Theoretical calculations indicate that when the friction coefficient between the front tires of a helicopter and the deck is greater than 0.1363,the helicopter will not experience instability or spinning.Simulation results show that under six level sea conditions,the rapid recovery system can continuously and safely anchor the helicopter through a rapid secured device within±3°.The above theoretical and simulation calculations provide strong support for the tethering safety calculation of helicopter under high sea conditions.
