| Abstract: | This article uses Solidworks to build three-dimensional geometric model of the box girder of crane,uses the finite elment HYPERMESH preprocessing to build three-dimensional finite element model,reuses finite element method software NASTRAN model to analyze and calculate the box girder loads from the stress and deformation effectively.The simple model analysis on the dynamic characteristics offers a new approach to assess the performance and troubleshooting of the crane quickly and accurately. |
