Abstract This article presents a method to achieve the vibration response of wheel–rail beam system on the container crane and to reduce the vibration and improve the trolley speed. To investigate the coupled vibration of a trolley–beam dynamic system, the governing equation is excited to obtain the interaction during the trolley travel on the beam at high speed. We studied the wheel–rail beam system in the container crane and as the structure of the container crane is huge, its beam span is more than 80 m long, the trolley runs on the large elastic beam, the beam deformation will have a significant impact on the structure. The dynamic load produced by the trolley acts on the elastic rail of the beam, which makes major deformation and vibration of the beam. To achieve the procedure of large steel structure on coupling vibration response on the container crane, the model of trolley–beam coupling of large-span elasticity beam with finite element methods and using multi-body dynamic simulation is built. Analysis of trolley–beam coupling is made based on the crawl impact of trolley. We found that the trolley with the elastic wire rope has a real-time dynamic loading effect and it changes the coupled vibration features in the operation. Via analysis on crane vibration of different trolley speed and simulation, the actual artificial frame wave is obtained. The excitation response amplitude by horizontal load has been obtained and it has great effect on the transmissibility performance of the container crane. This study shows that the vibration of the wheel–rail beam system cannot be neglected when increasing the trolley speed on the crane. The vibration response features of partial impact on ground point are done when trolley is running. The measures had been found to reduce the vibration of the container crane operating at high speed.

高速岸边集装箱起重机轮轨梁系统耦合振动研究

摘要 本文提出了一种实现集装箱起重机轮轨梁系统振动响应、减小振动、提高小车速度的方法。为了研究小车-梁动态系统的耦合振动，激发控制方程以获得小车在梁上高速行驶期间的相互作用。我们研究了集装箱起重机中的轮轨梁系统，由于集装箱起重机结构庞大，梁跨度超过80 m，小车运行在大弹性梁上，梁变形会产生显着影响结构上。小车产生的动载荷作用在横梁的弹性导轨上，使横梁发生较大的变形和振动。为实现大型钢结构在集装箱起重机上耦合振动响应的过程，采用有限元方法建立了大跨度弹性梁小车-梁耦合模型，并采用多体动力学仿真。小车-梁耦合分析是根据小车的爬行影响进行的。我们发现带有弹性钢丝绳的小车具有实时动态加载效果，它改变了运行中的耦合振动特征。通过对不同小车速度下起重机振动的分析和仿真，得到了实际的人工框架波。得到了水平载荷的激振响应幅值，对集装箱起重机的传递性能有很大影响。本研究表明，在起重机上提高小车速度时，不能忽略轮轨梁系统的振动。小车运行时对地面点局部冲击的振动响应特征。已发现这些措施可以减少高速运行的集装箱起重机的振动。
