摘　　要：针对现役综合系留和转运系统(Aircraft Ship Integrated Secure and Traverse,ASIST)存在的捕获冲击力大、转运时系统能耗高的问题,设计舰载直升机电驱动助降装置。通过分析助降装置的工况得出助降装置在执行捕获与转运任务时的性能要求,据此给出电驱动助降装置传动系统的设计方案。基于功率键合图理论建立传动系统的动力学模型,并与液压驱动助降装置进行对比仿真实验。仿真结果表明:电驱动助降装置的捕获速度降低约92%,捕获时最大冲击力降低约94%,能够在21 kN的外负载作用下执行直升机转运任务,在执行转运任务时能耗降低约29%,该成果对于拓宽ASIST的使用范围、降低系统能耗具有重要意义;所引入的兼顾系统动态特性与能耗特性的建模方法,为其余复杂机械系统的动力学建模提供了参考。An electric landing assist device for shipborne helicopter is designed to address the problems of significant capture impact and high energy consumption of aircraft ship integrated secure and traverse(ASIST)system.The performance requirements of landing assist device during the capture and transshipment tasks are presented by analyzing the working conditions.According to this,a transmission scheme of electric landing assist device is proposed.A dynamics model of the transmission system is established based on the theory of power bond graph;The proposed dynamics model is compared with the hydraulic landing assist device through the simulation test.The results show that the capture speed is reduced by about 92%,and the maximum impact force is reduced by about 94%.The electric landing assist device can execute the helicopter transshipment tasks with an external load of 21 kN and reduce energy consumption by about 29%.These research achievements are of great significance for broadening the application scope and reducing the energy consumption of ASIST.In addition,the introduced modeling method,which considers both the dynamic and energy consumption characteristics,also provides a reference for the dynamic modeling of other complex mechanical systems.
