摘　　要：采用一维理想气体流动的有限元状态变量模型,运用模块化建模与仿真方法和Fortran90语言进行了某液体火箭发动机试验台贮箱增压系统工作过程的仿真,获得了细致的管网状态参数分布曲线,为分析贮箱增压系统的工作过程及各组件的作用提供了数值依据。数学模型和模块化建模与仿真方法显示出较好的有效性和通用性。Using the finite element state-variable model for one-dimensional ideal gas flow, a modularized simulation model was established, and then the working process was calculated for the tank pressurization system of LRE test-bed. Detailed distribution curves of state parameters for the pipe net were obtained, which could be used to analyze the working process of the system and the function of every component. The mathematical model and the method of modularized modeling and simulation were validated to be effective and versatile.
