基于最大熵有序加权平均法的门座起重机结构可靠度优化分配

摘要

The paper introduces the application of the maximum entropy ordered weighted average allocation in the portal crane which effectively solves the shortcomings of traditional methods and leaves out the pre-estimate of reliability. The results show that the method is not only accurate and effective, but also can get the best distribution result of the failure rate, thus to achieve the optimal reliability allocation of portal crane structure, and provide an important basis for the rational design of the portal crane.%介绍了最大熵有序加权平均分配方法在门座起重机结构中的应用,有效地解决了传统方法的缺点,无需事先的可靠度预计.结果表明,该方法既准确有效,且能得到最佳的失效率分配结果,从而实现门座起重机结构的可靠度最优分配,为其合理设计提供重要依据.
