摘要
研究了推进剂贮存老化寿命计算及可靠性评定问题。首先由反应论模型计算得到不同评定参数下的寿命数据;然后采用三参数威布尔分布估计方法对寿命数据进行了概率拟合;最后讨论了利用混合威布尔分布参数估计方法研究寿命数据概率分布拟合方法的问题。
The methods of prediction of solid propellant storage life and storage reliability evaluation were studied. First, the storage life of propellant with different aging characteristics was calculated using reaction theory life model. Then, the 3-parameter Weibull distribution was adopted to fit the storage life data. Finally, the mixed Weibull distribution was studied to evaluate the storage reliability of solid propellant.
