| 摘 要： | 根据集装箱门式起重机小车轨距大的特点，建立了小车架为弹性结构时门式起重机的3个质量3个自由度串联弹性动力学系统振动模型，用模态分析法获得系统动态特性的数值精确解，并以实例计算结果与传统的双质量系统进行了比较，得到了小车架、桥梁结构和绳滑轮系统3者不同的动载系数值。

| Abstract: | Unlike conventional dynamic calculation in which rigid models are used, a serial elastic model of three masses and three degree of freedoms for the trolley frame of container gantry cranes is proposed by taking the large span of the trolley beam into consideration. The precise solutions to the vibrating equations are obtained by using modal analysis. The results show that the dynamic coefficients of the trolley frame, the gantry structures and the wirerope-pulley system are different |
