摘　　要：低温推进剂贮箱用于贮存运载火箭能源,其气液参数分层现象影响液体火箭发动机推进剂输送系统特性。根据模块化建模和仿真思想,应用AMES-im（advanced modeling environment for simulations of engineering systems）软件开发了低温推进剂贮箱分布参数仿真模型。结合AMESim软件固有模型,建立了一种采用气瓶贮气式增压方案的增压输送系统仿真模型,对系统整个工作过程进行了仿真,较好地反映了低温推进剂贮箱的分布参数特性。Cryogenic propellant tank stores the energy source of liquid rocket,and the gas-liquid stratification phenomena affects the characteristics of the propellant pressurization system for liquid-rocket engine.According to the methodology of modularization modeling and simulation,the distributed parameter simulation model for cryogenic propellant tank is constructed based on advanced modeling environment for simulations of engineering systems（AMESim） software.A kind of gas-pressurized system with gas cylinders is simulated and the distributed parameter dynamic characteristics of the tank are well reflected by the constructed simulation model.
