本文分析了桥式起重机垂直振动衰减时间的现行标准,指出了作为此标准的基础的某些假设是毫无根据的;提出了每提升载荷一次,起重机桥架加载循环次数的确定方法。
This paper analyzes the current standards for the vertical vibration decay time of overhead traveling cranes and points out that some of the assumptions used as the basis of this standard are groundless. The method for determining the number of loading cycles for crane bridges is proposed for each hoisting load.
