Reliability analysis of arm structures for radial gate based on detection data

锈蚀导致钢闸门的静力和动力特性发生变化的同时,改变了闸门体系的可靠度.为研究锈蚀对钢闸门可靠度的影响,本文基于现场检测数据分析了闸门锈蚀特性,采用三维有限元方法分析弧形钢闸门支臂应力,并计算了支臂的可靠度.结果表明,本文提出的方法可准确地计算钢闸门支臂的可靠度,以判定闸门的安全性.

Rust causes the static and dynamic characteristics of the steel gate to change,but also changes the reliability of the gate system.In order to study the effect of rust on the reliability of steel gate,this paper analyzes the characteristics of rust based on field detection data,analyzes the stress of arc steel gate support arm by using three-dimensional finite factor method,and calculates the reliability of the support arm.The results show that the method proposed in this paper can accurately calculate the reliability of the steel gate support arm to determine the safety of the gate.
