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.
Keywords�� oxygen supply system   oxygen regulator   computer simulation   optimization design
