摘要： 基于动力相似理论，推导了集装箱码头岸边起重机（简称岸桥）原型结构和1∶50缩比模型的相似比例因子；利用锤击模态试验和地震振动台试验分别获取了1∶50缩比模型的动态特性和地震响应；同时，使用ANSYS软件对原型结构相应的动态行为也进行了系统地分析.研究结果表明,1∶50缩比模型能够准确地预测出其原型结构的动态特性和地震响应，并能为后续的研究提供一个可靠的试验模型.

Abstract: Based on the dynamic similitude theory, a detailed deduction process on the similarity scale factors between the prototype and 1∶50 scale model was presented. A hammering modal test and a series of seismic shaking table tests were successively carried out to obtain the dynamic characteristics and the seismic responses of this 1∶50 scale model. Meanwhile, the corresponding dynamic behaviors of the prototype were also systematically analyzed by the use of the ANSYS software. The investigation results indicate that the 1∶50 scale model can accurately predict the dynamic performances and seismic responses of the prototype with small error and can provide a reliable testing model for the following studies.  

Key words: quayside container crane, dynamic similitude theory, shaking table tests, earthquake action, finite element analysis
