摘要
针对武器装备可靠性计算中概率分布参数的不确定性评估问题,通过抽样方法构造极限状态函数的响应面,在标准正态空间中计算可靠性指标的置信限,再将其转化为可靠度置信限。导弹隔框蒙皮的可靠度置信限计算问题验证了这种方法的有效性、准确性,该方法可以应用于试验样本较少的复杂大系统。
For estimating uncertainty of probability distribution parameters in reliability calculation of weapon equipment, response surface of limit state function is modeled by sampling and confidence limits of reliability index is calculated in standard normal space, which can translate into confidence limits of reliability. The method＇ s availability and veracity is proved by calculating confidence limits of reliability of missile searfskin, and it can be applied to complicated system with small sample size.
