燃气发生器点火器的性能可靠性评定

Performance reliability assessment of the ignition device for a gas generator

应用蒙特卡罗数值模拟与二项分布累积概率评定方程相结合的方法 ,对某燃气源点火器的性能可靠性进行评定。计算结果表明 ,该方法能充分利用试验信息 ,减少试验的样本量 ,提高可靠度评定的精度和置信度 ,节减经费 ,缩短研制周期。

The paper uses Monte Carlo digital simulation and reliability assessment equation of binomial distribution to assess the performance reliability of the ignition device for a gas generator. This methood of reliability assessment can not only adequately use test information, reduce the quantity of specimens, but also improve precision and confidence level of assessment. So the method may evidently save spending and shorten research period.
