| Abstract: | By using Bayesian method and based on the accumulated test data,the performance reliability simulation models of solid rocket motors are established. The simulation credibility test with maximum entropy spectrum method is presented .The approximate distribution of performance reliability is determined in accordance with simulated pretest data and in-situ test data. Finally, the paper gives an example to show Bayesian approach's validity. |
