摘要
对液压能驱动的飞控系统功率进行全飞行过程的仿真分析,可为液压能源管理方案以及液压能源系统的设计提供定量参考。为此,文中设计一种基于分布式仿真的飞控系统功率分析方法,首先结合典型飞机飞控系统舵面参数,利用AMEsim软件建立飞控系统7类典型舵面的功率仿真模型;然后在基于DDS软总线的分布式仿真平台上,通过典型飞机真实飞行状态参数激励整个飞控系统仿真模型,得到飞控系统在工况下全飞行过程的舵面作动器关键参数;再对7类飞控系统舵面的功率分别进行计算。通过分布式仿真平台实现了整个飞控系统7类舵面模型的协同仿真及全工况下的飞控系统综合功率分析。仿真实验结果表明:在不同飞行阶段,飞控系统功率消耗差异较大;飞控系统功率消耗呈现为脉冲式,起飞阶段平均功率消耗最高,巡航阶段飞控系统平均功率消耗最低。
As the simulation analysis of the power of the flight control system driven by hydraulic energy can provide quantitative reference for the hydraulic energy management scheme and the design of hydraulic energy system,a flight control system power analysis method based on distributed simulation is designed.Combining with the control surface parameters of typical aircraft flight control system,the power simulation model of seven types of typical control surface in the aircraft flight control system is established by means of the AMEsim software.On the distributed simulation platform based on the DDS soft bus,the whole flight control system simulation model is excited by the real flight state parameters of typical aircraft,and the key parameters of rudder actuator in the whole flight process of the flight control system under the operating conditions are obtained.The power of rudder surface of seven types of flight control system is calculated respectively.The collaborative simulation of seven types of rudder surface models of the whole flight control system is realized on the distributed simulation platform,and the comprehensive power analysis of the flight control system under all working conditions is realized.The simulation experiment results show that the power consumption of the flight control system varies greatly in different flight stages.The average power consumption of flight control system is the highest in takeoff stage and the lowest in cruise stage.
