岸边集装箱起重机门架结构的有限元分析与比较

摘要

针对常见的复合型门架结构和单斜撑型门架结构,利用ANSYS软件对岸桥集装箱起重机钢结构进行有限元建模,分析比较其应力、变形和模态振动等方面情况.分析结果显示在各项性能参数相同的情况下,由复合型门架结构改变为单斜撑型门架结构,其应力、应变和固有特性的变化不是很大;提升联系横梁,采用单斜撑型门架结构可行,它可以节约钢材、降低成本、提高横梁下运行净空高度.%For the familiar doorframe structures of composite type and single oblique pole type, building a finite model of container crane steel structure by ANSYS, stress strain and mode vibration are analysed and compared. It's acquired that in the condition of the same performance parameter, changing doorframe structure of compound type into single oblique pole type, the changes of stress strain and inherent characteristic are little; heightening contact crossbeam and adopting doorframe structures in single oblique pole type is feasible, which could economize steel, reduce cost and heighten moving headroom height below the contact crossbeam.
