大圆形轨双桥架式起重机桥架的稳定性和抗振性能

Stability and anti-vibration of double-bridge crane along large round track

介绍一种特种起重机桥架的力学结构设计方法,针对该起重机旋转半径大,桥架尺寸大且置于高空,室外作业等特点,通过力学分析和反复试验,解决了实践中碰到的桥架振动大,稳定性差等问题。

This paper introduces a way of how to design special crane bridge frame with structural mechanics. In view of large radius of track, large size of bridge frame＇ high suspension and outdoor operation, it solves some problems about its stability, anti - vibration and etc by mechanics analysis and test.
