摘要
通过理论分析与实测,研究了梁式起重机在各种工况下的动载荷以及分布规律,得出设计时应考虑的最不利工况。同时提出适合梁式起重机特点的动载系数简化计算公式和典型工况下的操作系数,供参考使用。
Dynamic load of single girder crane under various operational conditions and its distribution are studiedby theoretical analysis and experimental measurement. The most unfavourable operational condition to be con-sidered at design stage is given. Simplified formulas for calculating dynamic factor and operation factorunder typical operational conditions, which is appropriate for special characteristics of such cranes, is alsogiven for reference.
