摘要
对某固体火箭发动机系统，用三种可靠性仿真方法：直接仿真方法、期望估计技巧以及拟仿真方法，分别进行了系统可靠性仿真运算。给出了相对应的算法，运行按算法编写的Ｃ 语言程序，得出各种仿真方法的仿真结果并进行了分析。然后对仿真结果的误差进行分析，从误差、时间及算法复杂性几个方面进行了比较，从而挑选出符合该发动机系统可靠性仿真要求的仿真方法。
The paper uses three simulation methods: Straight simulation, Expectation estimating technique, and imitative simulation to simulate certain type of solid engine system. Reliability calculation and corresponding algorithms are given. The program is compiled, the results are listed and compared. After the error analysis of the results, the difference of error, time and the complexion of algorithms are compared. Thus the most adaptable simulation method for the solid engine is fixed.
