中文摘要：
港口向离岸深水化、设备密集化的发展对港口装卸设备的防风能力提出了更高要求,文中以港口门座起重机为对象,对突发强阵风下门座起重机的风场特性、整机风载进行了研究。运用计算流体动力学理论和流固耦合分析方法,分析了强阵风作用下码头前沿流体场的压力和流速分布特征。运用ADINA的流固耦合分析功能,对起重机进行了数值风洞模拟与分析,并对不同工况下起重机各个坐标方向上的风载荷合力以及合力矩进行了量化计算,根据结果对门座起重机的防风方式进行了分析,从而为目前港口起重机的防风安全提供管理策略和理论依据。
英文摘要：
The offshore,deepwater and equipment concentration development trends of port requires better windbreak capacity of port handing equipments.The portal crane is taken as research object,and the wind field＇s characteristics and whole crane wind load of the portal crane under sudden strong winds or gusts are researched.The CFD theory and FSI analysis methods are used to analyze the distribution of pressure and velocity in the apron fluid field.According to the results,the fluid structure interaction analysis function of ADINA software are used to make numerical wind tunnel simulation and analysis,and quantify wind load＇s composite force and moment in each coordinate direction of the crane.Base on above results,the ways of port windbreak are analyzed and the results will provide management strategy and theoretical basis for windbreak safety of port crane.
