摘要

摘要: 起落架收放控制系统设计需考虑多种约束条件和影响因素,系统仿真平台的使用是辅助系统设计的重要手段.基于流体系统仿真软件Flowmaster,建立了大型飞机起落架收放控制系统液压附件仿真模型,在此基础上构建了完整收放控制系统仿真模型.基于建立的系统仿真模型,进行了正常飞行状态下起落架收上过程仿真分析,仿真结果给出了液压作动器尺寸设计对收放过程中系统入口压力需求、系统液压流量及起落架收放时间的影响.该仿真方法可用于起落架收放控制系统初步设计及多种飞行状态下设计方案的校核.

Abstract: A variety of constraints and influence factors need to be considered in landing gear retraction and extension (R/E) control system design. System simulation platform is an important auxiliary method for the system design. The hydraulic accessories simulation models of large-scale aircraft landing gear control system were established based on the fluid system simulation software Flowmaster, and the system simulation model was constructed using the established component models. Analysis of the landing gear retraction process for normal flight state was conducted based on the present system simulation model, and impacts of the actuator size on system entry pressure requirement, hydraulic fluid flowrate and the gear retraction time were also provided. The simulation method can be used for the preliminary design of the landing gear R/E control system and the verification of system design for different flight conditions.
