摘　　要：本文采用了有限元动态理论对ＱＴＺ８０ｔ－ｍ塔机在吊重离地起升和起重臂加速回转工况下进行了动态响应分析，求得了动载响应的时间历程，并根据计算结果用图、表的直观型式描述了起重臂的位移、应力与时间的关系。In this article the dynamic response analysis of the QTZ80-t-m tower crane are achieved by the finite ele ment dynamic theory in the condition of the cargo lifted from ground and the lifting-arm accelerating rotation,from which the time course of the dynamic response are achieved. In the end,the relationship of the displacement stress of the lifting-arm and time are described by graph according the computation.
