中文摘要:飞机液压系统的一个重要设计指标是能够满足全飞行剖面场景下的负载流量需求。介绍了一种用于飞机液压系统负载流量需求分析的数字仿真分析方法,通过开发数学模型构建了液压能源子系统和液压用户的负载子系统模型,进而仿真分析典型飞行剖面下液压系统的负载流量需求,模拟了飞机液压系统的动态工作过程,能够反映飞机液压系统与液压用户负载之间的耦合动态特性。仿真结果表明,这套模型满足液压系统分析需求,可用于液压系统的设计支持工作。
英文摘要:An important design indicator of aircraft hydraulic system is to meet the load flow demand in full flight profile scenes. This paper introduces a digital simulation analysis method of load flow demand for aircraft hydraulic system. According to the actual structure of the hydraulic system, mathematical models are developed to build the load subsystem model of the hydraulic energy subsystem and the hydraulic users. And then the simulation analysis of the load flow requirements of hydraulic system was carried out under typical flight profiles. The dynamic process of the aircraft hydraulic system is simulated, which can reflect the coupling dynamic characteristics between the aircraft hydraulic system and the hydraulic user load.The simulation results show that the hydraulic system model meets the requirements of hydraulic system analysis and can be used for hydraulic system design support.
