Offshore Deep-water Port Machinery Group Of Wind Load Calculation Method Research

In decades of reforming and opening up, China's GDP kept high-speed growth, the trade between China and international developed rapidly. today.China's GDP could become the second economies exceed Japan, import and export trade is more and more bigger, International shipping company is currently large-scale using six generations ship container ship and its draft depth is at least 14 meters,If you want to enter the port mooring,of course requirements channel depth and terminal quay in depth of water are 15 meters below.A port, with no deep-channel and deep-water berths,cannot accept large container ships,can only be regional port and feeding port, only for large deepwater supporting services. So the deep-water port in China have great demand, and in the future deepwater port is building larger overall trends towards.Hence,this paper joint international and domestic shipping line,can get deep analysis of importance and necessity of construction of shoreline. And in the meanwhile, establishing deep water port in order to match the big shipping companies increasingly large capacity, loading and unloading port container ship large equipment group of structure design also appears especially important.In port, machinery group show biger, finer, longer, higher flexible characteristics at the same time, more and more toward large-scale, professional direction. These characteristics can make crane wind load, more sensitive to wind vibration phenomenon and more apparent, easily lead to massive storm accident, then port machinery group of wind load calculation method research importance is reflected in these places.The paper's research content basically is the following:1) single fixed component of port crane was part of the wind load research;2) fluid movement theory's analysis;3) the quayside container crane and crane group's model establishment;4) quayside container crane model simulated;5) quayside container crane's numerical simulation of model;6) The concrete measures and analysis of single large equipment for windbreak. On the basis of the theory of fluid motion, mainly doing some numerical wind tunnel tests about the shore cranes and crane group, compared with the formula, first it has proved the feasibility and certainty of ansys software, then respectively found that the land bridge crane, before the typhoon comes, could be more resistance to flat beam in the wind. when the distance is right, the wind load (namely wind capacity) of the first quayside container crane in the crane group is especially important.
