| Abstract: | The structure analysis for the rigidity and intensity of a crane girder whose span is 48 m in length are conducted by the finite element method.The stresses and deformation distributing of several section under four type load circumstances are obtained.The result reveals that the stress distributing of the whole girder is uneven and the girder has weight-saving potential.Based on the results the structure size is improved and the deadweight is reduced by 18.23% for the improved structure parameters. |
