Investigation on opening mechanism of World Expo Bridge
【摘要】 介绍了世博庆典舟桥开启过程及三种开启机构设计方案:双轴承液压缸驱动方案、双轴承螺旋桨驱动方案以及单轴承螺旋桨驱动方案;分别分析计算液压缸的功率、脉动情况及螺旋桨功率.
【Abstract】 This paper introduces the opening process of the World Expo Bridge and three design options of opening mechanism: namely hydraulic-cylinder-driven mechanism using double bearings, propeller-driven mechanism using double bearings, and propellers-driven mechanism using one bearing. Finally, the power and ripple of hydraulic cylinders, together with the power of propellers, are analyzed.
