| Abstract: | This paper describes a wind tunnel test for a full portal crane aeroelasticmodel in laminar flow and turbulent flow with wind profile.The test wasconducted in 8 wind directions,i.e.,4 angles of rotation,and 3 pitch angles.The wind speed of the test can often be seen in ports.Some conclusions,inclu-ding the charateristics of excitation and vibration,as well as dangerous workingconditions of the crane,are obtained.A phenomenon of comparatively intense-vortex-induced along-wind vibration is observed.Based on the test results,in addition,two principles of wind resistance design are proposed. |
