| 摘 要： | 为了研制一种较为通用的液体火箭发动机工作过程的仿真软件，依据模块化建模思想，建立发动机各组件的Simulink仿真模块。根据发动机系统中各组件之间的参数信号传递关系，连接各模块的相应输入输出端口即形成整个发动机系统的仿真模型。对某型发动机的起动过程进行仿真计算，结果表明这种模块化的建模仿真方法易操作，较通用。

| Abstract: | According to module modeling requirements, the components and the parts in a liquid propellant rocket engine (LRE) were classified firstly. Then, the simulation blocks of LRE components and parts based on MATLAB Simulink were constructed, which can be used to develop a universal simulation software for LRE dynamic characteristics study. Based on the parameter signal transfer relations between LRE components and parts, the LRE simulation model can be set up by connecting the corresponding LRE component input and output ports. The startup process of a certain LRE was simulated. The results show that this simulation method is effective, easier to operate, and more general. |
