摘要: 阐述了某型航空氧气调节器肺式机构和空气进气机构的工作原理,对运动部件进行了受力分析并建立相应的数学模型.以供氧系统的性能技术指标和使用条件作为设计计算约束,根据数学模型,利用MATLAB/simulink软件建立仿真计算模型.在此基础上通过仿真计算特性曲线分析完成了系统主要结构参数的选取,并得出了系统的流量特性以及整个飞行高度上的含氧百分比特性.仿真结果表明:以上提出的设计计算方法对航空氧气调节器进行设计与改进是可行的.Abstract: The working principle of the two components(pulmonary-based institutions and air intake body of oxygen regulator) was presented, and the mathematical model was established based on the analysis of the balance of the imposed forces on the kinetic components. The numerical simulation was implemented through MATLAB/simulink with the technical performance and operating conditions of oxygen supply system as the designing and calculating constraints. The selection of the main structural parameters was achieved through the analysis of the characteristic curve attained from the simulation results, and the flow characteristics of the system together with the characteristics of the oxygen percentage on a whole altitude were drawn. The simulation results show that the method are feasible for design and performance improvement for the oxygen regulator.
