Design and Static Analysis of I Section Boom for Jib Crane Use of FEM (ANSYS)

The structural action of a rectangular cantilever beam under loading is predominantly bending, with other effects such as, warping, rotation, and lateral torsional buckling, the study includes an investigation of stress level for load carrying capacity and bending of regular I section cantilever beam of jib crane subjected to self-weight and eccentric point load at the free end. A new design is proposed in this study to tackle the bending and increase the strength of the crane. The corrugated plate is a widely used structural element in many fields of application because of its numerous favourable properties related to resistance in out of plane twisting. Standardization of jib crane design procedures enables designers to develop their own jib crane automation modules for entire jib crane design applications. Since main effort and time for implementation of the jib crane design procedures are generally spent for interpretation and explanation of the available jib crane design standards, a computer-automated access by using parametric modelling to the available standards may improve speed, reliability and quality of the design procedures. Starting from the fact that components of jib cranes are generally composed of similar mechanical and electrical sub-components independent of the crane type a general component tree of jib cranes is developed for automation purpose. Design Modules of cranes are defined from the developed component tree of the cranes based on the available design procedures. Independent Design Procedures are defined as atomic design modules of the jib crane design procedures by considering computational approaches and rules in the "F.E.M. Rules" for each jib crane component. The "F. E. M. rules" is selected for this purpose because of its widespread use and established popularity among the jib crane manufacturers. Access to the "F. E. M. Rules" from any design procedure is fully automated by using a systematic approach of parametric modelling. The parametric model can be used for various jib crane design cases as well as further for optimization. Finite element analysis is carried out to analyse the effect of geometrical parameters of various web shapes. The thickness of flanges is constant for the samples with length of 2.4 m and tested for 500Kg load lifting capacity. Structural analysis is done to examine the influence of the section dimensions due to eccentric point load at the free end on cantilever.
