基于Monte-Carlo的起重机金属结构安全评价方法
|
摘要
针对当前起重机行业对结构安全评价的迫切需求,本文从可靠性设计的角度提出了一种可用于起重机结构安全性评价的设计方法—基于Monte-Carlo的起重机结构安全评价法。采用Monte-Carlo法对某起重机厂设计的某型号起重机进行了研究,结果表明,在对起重机结构进行设计的过程中,该方法可有效的对起重机结构的可靠性(安全性)进行评价和分析,并获得能够准确评价起重机结构安全性的定量化指标,对起重机结构的设计具有一定的指导意义。
In view of the urgent need of crane industry for structural safety evaluation, this paper proposes a design method for crane structural safety evaluation from the perspective of reliability design-Monte-Carlo based crane structural safety evaluation method. The Monte-Carlo method is used to study a certain type of crane designed by a crane factory. The results show that the method can effectively evaluate and analyze the reliability(safety) of the crane structure in the process of designing the crane structure and obtain quantitative indexes that can accurately evaluate the safety of the crane structure, which can serve as a guidance to the design of the crane structure on some degree.
