摘　　要：探讨了基于Simulink的航天服便携式生命保障系统建模与仿真方法。采用集总参数法建立了能够计算温度、湿度、CO2浓度等参数的生保系统仿真模型。针对美国现有的舱外航天服生命保障系统建立了瞬态仿真模型,并进行仿真研究。分析仿真结果表明,建立的仿真平台能够较好地预测航天服便携式生保系统的运行状况。建立的模型,具有模块性和通用性,易于扩展,对我国航天服生保系统的研制与优化具有借鉴意义。The modeling and simulation methods of space suit portable life support system （PLSS） based on Simulink were discussed. A lumped parameter approach was used to model the life support system. The model could calculate various parameters include temperature, humidity, and CO2 concentration. Dynamic model of the current USA extravehicular activity （EVA） space suit PLSS was developed for simulation studies. Analysis results show that the test bed can evaluate the dynamic performance of EVA space suit PLSS reasonably. The model is provided with modularity and flexibility, and the method are of significance for the research and optimization of space suit PLSS in our country.
