用极限分析法评估门式堆取料机活动梁变形后的安全性

摘要

用塑性力学理论计算出门式堆取料机活动梁的最大允许塑性变形,从而为判断出现了塑性变形的活动梁结构是否还处于安全状态提供了依据,对紧急情况下设备的有条件使用有一定参考价值.%The plastic mechanics theory is applied to calculate the maximum allowable plastic deformation of moving beam of gantry stacker/reclaimer, in order to provide basis for judging whether the plastically deformed moving beam structure is under the safety state or not, which can provide certain reference for conditional operation of the equipment in emergency.
