| 摘 要： | 提出一种确定性仿真结果(不考虑随机因素影响的仿真结果)检验方法, 能够对仿真结果与试验结果之间的误差进行分析, 确定该误差是由于仿真不正确引起的系统误差, 还是由于试验结果的分散性引起的偶然误差, 进而判断仿真结果正确与否.同时建立一种确定性仿真结果多因子分析方法, 能够对仿真结果的各个影响因素(因子)进行分析, 确定哪些因素已被正确仿真, 哪些因素尚未被正确模拟, 从而指导仿真软件的编制. |

| Abstract: | A test method for determinate simulation results,in which random factors are not taken into account,is presented.It can analyze the error between simulation and experiment results,distinguish between system error caused by simulation incorrectness and accident error caused by the scatter of experiment results,and determine whether simulation results are right or not.A method for multiple factors analysis of determinate simulation results is also presented,which can analyze every influencing factor of simulation results and determine which factors have been simulated correctly and which have not.In this way,the method can guide the programming of simulation software. |
| Keywords: | aerospace propulsion system simulation test factor analysis small sample model verfication |
