3-D Modeling And Finite Element Analysis Of EOT Crane

The design of an overhead crane with a double box girder has been investigated and a study of a crane with 10 ton capacity and 12 m span length has been conducted.It is not possible for the real experimental studies to take into consideration the influence of the connections between the main beams and the rest parts of the construction, the influence of the longitudinal and transverse ribbings as well as the influence of the supports on the overall stressed state of the construction. Moreover, the researches that use for the majority of the test cases different strain measurement sturn out to be quite hard and expensive. All these problems could be solved successfully by the use of computer modelling procedures. It is possible to perform 2D or 3D computer studies. The 2D computer studies give idea of the planar behaviour of the construction and lack the opportunity of showing the influence of supports or the connections of the construction. It is only the 3D models that could satisfy all the requirements for examining the general stressed state of the carrying metal construction. With regard to this, the creation of 3-D models for researching and analysing the behaviour of an overhead crane, becomes the main goal of the present workIn the initial phase of the study, conventional design calculations proposed by Indian Standard Rules were performed. The crane design was modelled with solids Loads and boundary conditions were applied to solid model. Assign material to the solid model. Finite Element meshes were generated from the solid model. After a comparison of the finite element analyses, and the conventional calculations, the analysis was found to give the most realistic results. As a result of this study, a design optimization method for an overhead crane is proposed.
