葫芦小车圆弧轨道曲梁的分析与计算探讨

Discussion on Analysis and Calculation for Hoist Crab Circular Rail Curve Girder

本文针对葫芦小车圆弧轨道曲梁的结构和受力特点进行了探讨与分析,推导提出了计算圆弧曲梁的实用公式,并讨论了曲梁支座刚度的变化和薄壁曲梁存在的约束扭转因素对曲梁强度的影响,最后推荐了解决该问题的方法。

In this paper the author approaches the structure analyese external force characteristics of the circular curve girder, have deduced the calculation formulas for circular rail curve girder, and have discussed the influences cf curve girder suppert stiffness changes and the constrained torsion factor that consisted in thin-walled curve girder on curve girder strength.Finally,recommende a solution method for this engineering problem.
