摘要
提出一种通过代数和计算可靠度保守估计的方法,导出了损伤服从不同分布时可靠度保守估计的条件.结合应用实例,对比本文计算结果和Monte-Carlo模拟结果,验证了本文所提方法的可行性与合理性.
A method in estimating the conservative reliability by calculating algebraic sum of damage is proposed. The conditions that this method could be used to get the conservative estimation is calculated for several distributions. Combined with application examples, the feasibility and rationality of this method are validated by comparing the results of this method and Monte-Carlo simulation.
