摘要
文中通过CFD仿真获得全船流场信息,将玻璃幕墙结构的风压荷载作为输入,采用有限元仿真分析中型邮轮在不同速度及角度行驶过程中玻璃幕墙区域的流场特性和振动特性.数值计算结果表明:在全船流场影响下,玻璃幕墙的迎风面与结构角隅处压力较大;随着速度增大,玻璃幕墙结构的振动位移逐渐增大;当风速恒定时,30°风向角与60°风向角的振动位移较大;当风向角与速度恒定时,顶层与底层玻璃幕墙结构的振动位移较大.
The flow field information of the whole ship was obtained by CFD simulation,and the wind pressure load of the glass curtain wall structure was taken as input.The flow field characteristics and vibration characteristics of the glass curtain wall area of a medium-sized cruise ship were analyzed by finite element simulation during different speeds and angles.The numerical results show that under the influence of the whole ship flow field,the pressure on the windward surface of the glass curtain wall and the corner of the structure is greater.With the increase of speed,the vibration displacement of glass curtain wall structure increases gradually.When the wind speed is constant,the vibration displacement of 30 wind direction angle and 60 wind direction angle is large.When the wind direction angle and speed are constant,the vibration displacement of the top and bottom glass curtain wall structures is large.
