摘要
用ＳＡＰ８４程序对ＴＱＺ１００塔机结构进行了有限元分析，建立了塔机计算模型，对作用在塔机上的几种载荷进行了恰当处理，找出了最危险工况，确定了塔机最大起重能力，并得出一些有益的结论。
By using the programme SAP84, the structure if tower crane TQZ100with the method of finite element is analysed, and the m,athematical modelS are establishedto several loads exerted on the towercrane. Finally, the'most dangerous site 'is found out,and the greatest hoisting ability is determined. Meanwhile, many beneficial concluSions areobtained.
