| Abstract: | There are many brace structures on the bridge type ship unloader, and their slenderness are larger and easier to produce wind-induced vibration effects under the gale or hurricane. Based on the hydromechanics knowledge, the static displacement method and the finite element software of ANSYS, the wind-induced vibration of braces is analyzed with examples, and then some measures are put forward to prevent wind-induced vibration. |
