针对飞机液压系统的液压冲击问题,在分析液压冲击产生机理的基础上,运用AMESim仿真软件建立民用飞机液压系统动态特性仿真模型,并分析优先阀开启时间、管路长度、管径和壁厚对液压冲击的影响规律。仿真结果表明,通过增大优先阀开启时间,适当缩短管路长度和增大管径能够有效降低液压系统的液压冲击现象。所采用的研究方法和仿真模型能够为民用飞机元件和管路的参数匹配和布置安装提供理论依据。
Aiming at the hydraulic impact problem of aircraft hydraulic system, on the basis of analyzing the mechanism of hydraulic impact, the simulation model of dynamic characteristics of civil aircraft hydraulic system is established by using AMESim simulation software. The valve opening time, pipe length, pipe diameter and wall thickness Influence of hydraulic impact. The simulation results show that the hydraulic shock can be effectively reduced by increasing the priority valve opening time, shortening the pipe length and increasing the diameter. The research methods and simulation models can provide theoretical basis for matching and arranging the parameters of civil aircraft components and piping.
