青藏客车用氧气面罩的选型与仿真

Lectotype and Simulation of Oxygen Mask Used in Oxygen Supply System of Passenger Cars on Qingzang Railway

对比不同的供氧方法,选择BLB氧气面罩用于青藏客车供氧。建立了普通氧气面罩、BLB氧气面罩以及人体呼吸系统数学模型并进行仿真计算,结果表明BLB面罩能够有效节氧,适合青藏客车使用,并得到面罩的输入输出特性,为制氧系统的设计提供了依据。

Compared different oxygen supply methods, BLB mask was chosen for oxygen supply system of passenger cars on Qingzang railway. Mathematical models of BLB mask and respiratory system were established. The simulation result demonstrates that BLB mask is efficacious for economizing oxygen and acceptable for oxygen supply, system of passenger cars. Input-output characteristic of BLB mask is obtained and can be used for designing the oxygen supply system.
