Stability Analysis of Gantry Crane's Flexible Legs
以某工厂300t-43m门式起重机柔性支腿为研究对象,运用理论分析计算和有限元仿真分析2种方法对柔性支腿稳定性进行分析,校核了柔性支腿稳定性满足要求.对影响柔性支腿稳定性的3个因素(截面特性、长细比、壁厚)进行了积极探讨,找出影响柔性支腿稳定性因素的规律,为门式起重机安全评估研究提供依据.
This paper takes the flexible legs of a 300 t-43 m gantry crane as the object of study and analyzes the stability of the flexible legs by theoretical calculation and finite element simulation analysis.Its stability meets the requirement.The three factors of affecting the stability of the flexible legs (section properties,slenderness ratio and wall thickness) are actively explored and the law of affecting the stability of flexible legs is found.These provide …查看全部>>
